  • Toshiba Develops 6500 V Second-Generation IEGT Chip and Commercializes New Press-Pack Device for High-Voltage Power Systems

    Toshiba Develops 6500 V Second-Generation IEGT Chip and Commercializes New Press-Pack Device for High-Voltage Power Systems

    3 Min Read

    Toshiba Electronic Devices & Storage Corporation has developed a 6500 V-rated trench-type second-generation Injection Enhanced Gate Transistor (IEGT) chip featuring enhanced turn-off capability and short-circuit robustness. The company has also commercialized a new 6500 V press-pack IEGT (PPI) incorporating the technology for use in high-voltage applications, including HVDC transmission systems, STATCOM installations, and industrial motor drives.

    The new device increases the voltage rating from the conventional 4500 V class to 6500 V, enabling a reduction in the number of power semiconductor devices connected in series for a given output voltage. According to Toshiba, this contributes to simpler system architectures and more compact power conversion equipment.

    The development comes as the deployment of renewable energy continues to expand worldwide, increasing the need for efficient long-distance power transmission and advanced grid stabilization technologies. Since power generation sites and energy consumption centers are often geographically separated, high-voltage direct current (HVDC) transmission systems are becoming increasingly important. At the same time, the adoption of static synchronous compensators (STATCOMs) is growing to support grid stability.

    In these high-voltage power conversion systems, multiple semiconductor devices are typically connected in series. Increasing the voltage rating of individual devices reduces the number of required components, helping lower system complexity and equipment size.

    Toshiba has previously mass-produced 4500 V-class press-pack IEGTs. However, achieving reliable operation at 6500 V requires maintaining sufficient turn-off capability and short-circuit performance under significantly higher voltage conditions. This challenge is closely linked to the precise control of carrier transport within the semiconductor structure. In addition, variations in breakdown voltage observed during bias testing represented another technical hurdle.

    To address these challenges, Toshiba developed a new 6500 V IEGT chip featuring a shorted dummy cell structure in the cell region, eliminating floating regions that can cause unstable potential distribution. The company also optimized the mesa width within the current conduction region and introduced an N-barrier layer beneath the P-base layer responsible for carrier transport control.

    These structural enhancements improve carrier distribution and current flow throughout the device, resulting in more uniform current distribution during turn-off operation. Toshiba stated that this enables stable operation with sufficient turn-off capability and short-circuit performance under high-voltage conditions. The company also confirmed an improved trade-off between conduction losses and switching losses.

    In the termination region, Toshiba adopted a structure incorporating guard rings and a semi-insulating layer to distribute the electric field more effectively. This design enables breakdown voltages exceeding 6500 V. Additionally, optimization of the interface process between the semi-insulating layer and silicon suppresses breakdown voltage variations observed under bias stress conditions, contributing to more stable device characteristics.

    The newly developed chip has undergone turn-off and short-circuit testing at a voltage of 4500 V, confirming its suitability for high-voltage power applications.

    Based on this technology, Toshiba has commercialized the ST2000JXH35A, a 6500 V / 2000 A press-pack IEGT. In HVDC transmission systems, the use of 6500 V devices can reduce the number of series-connected semiconductor devices by approximately 33% compared with 4500 V solutions, contributing to lower system size and weight.

    Toshiba stated that it will continue developing press-pack IEGT technologies for high-voltage power conversion applications while expanding its product portfolio to support the advancement of power transmission and energy infrastructure systems.

    The technology was presented at PCIM Europe 2026, held in Nuremberg, Germany, from June 9 to 11, 2026.

    Infineon Introduces 18 kW PSU and 30 kW PFC Reference Designs for Next-Generation AI Data Centers

    4 Min Read

    Infineon Technologies AG has introduced two new system-level power solutions designed to address the evolving requirements of artificial intelligence (AI) data centers. The company unveiled an 18 kW three-phase power supply unit (PSU) reference design optimized for 50 V rack architectures and a 30 kW three-phase interleaved T-Type power factor correction (PFC) evaluation board developed for 800 VDC or ±400 VDC rack architectures with power sidecar configurations.

    The two solutions are part of Infineon’s broader AI server power delivery portfolio and are intended to help server ODMs and OEMs accelerate development while achieving higher rack power, improved efficiency, and enhanced thermal performance.

    As AI workloads continue to increase GPU power consumption and drive higher rack densities, data center power infrastructures are facing growing challenges. Infineon’s new designs are aimed at addressing these demands through advanced power conversion technologies and system-level integration.

    The 18 kW PSU reference design incorporates a new integrated energy buffer concept that smooths power demand from the electrical grid during AI-related peak loads, eliminating the need for a separate capacitor bank unit. According to Infineon, this approach enables more efficient use of stored energy and reduces the required capacitor volume by up to 50%, lowering both component costs and system footprint.

    The 30 kW PFC evaluation board utilizes Infineon’s CoolGaN™ semiconductor technology to achieve higher power density while reducing overall system cost, targeting data center operators expanding infrastructure to support increasing AI computing requirements.

    The 18 kW PSU reference design achieves a peak efficiency of 97.5% through a combination of 650 V CoolSiC™ MOSFETs, 80 V CoolGaN™ switches, EiceDRIVER™ gate drivers, and a PSOC™ microcontroller. At the core of the system is a five-level active neutral-point clamped (ANPC) PFC topology, designed to deliver high efficiency across the full load range, particularly under low-to-medium load conditions, while reducing the size of magnetic components.

    Infineon states that the ANPC topology provides a 0.2% higher peak efficiency at 50% load compared to a T-Type PFC design and a 0.4% improvement over a Vienna Rectifier topology.

    The design also incorporates a novel integrated planar magnetic structure that enables a compact, modular, and scalable high-frequency transformer configuration. The integrated energy buffer provides a 20-millisecond hold-up time and supports GPU electrical data peak processing (EDPP) loads of up to 180%, meeting demanding AI load transient requirements.

    The PSU accepts a wide three-phase input voltage range of 311 VAC to 528 VAC, allowing compatibility with global power grid standards. Thermal management has been engineered to support operation in ambient temperatures ranging from -5°C to 45°C.

    Measuring 104 mm × 710 mm × 40 mm, the PSU is designed to fit standard 19-inch rack enclosures while delivering a power density of 100 W/in³.

    The 30 kW T-Type PFC evaluation board combines 650 V CoolGaN™ bidirectional switches in the back-to-back switching path with 1200 V CoolSiC™ MOSFETs in the high-voltage power stage. The system achieves a peak efficiency exceeding 99%.

    Power control is managed through the programmable power control accelerator (PPCA) integrated into the PSOC™ C3 microcontroller, enabling precise current and voltage regulation with fast dynamic response. The design maintains input current total harmonic distortion (iTHD) below 5% for loads above 30% and achieves a power factor greater than 0.99 across most operating conditions.

    Current measurement is performed using the XENSIV™ TLE4978 isolated magnetic Hall plus Coil current sensor, which offers a bandwidth of 9 MHz, strong common-mode transient immunity (CMTI), and high measurement accuracy. These characteristics make the solution suitable for next-generation silicon carbide and gallium nitride-based power supply systems.

    The modular platform is designed for integration into a 1U full-size PSU form factor and targets high-voltage DC data center applications requiring accurate voltage regulation and effective thermal management under the dynamic operating conditions associated with AI workloads.

    Both designs are optimized for use with Infineon’s AI server power delivery portfolio, which spans the complete power chain from grid connection to processor core. The portfolio includes solid-state transformers, circuit breakers, power supply units, battery backup units, intermediate bus converters, and second-stage DC conversion power modules.

    Infineon Unveils 24 kW High-Voltage Battery Backup Unit Reference Design for AI Data Centers

    4 Min Read

    Infineon Technologies AG has introduced a 24 kW battery backup unit (BBU) DC-DC reference design for high-voltage (HV) DC bus architectures in artificial intelligence (AI) data centers. The solution is the first reference design of its kind to operate directly from a battery stack to an 800 V DC bus using both 650 V and 1200 V silicon carbide (SiC) technologies. It delivers a power density of 450 W/in³ and efficiency exceeding 99%, while maintaining the same physical form factor as current low-voltage BBU implementations.

    The reference design addresses a key infrastructure challenge as data centers increasingly transition toward higher-voltage DC power distribution architectures.

    “Powering AI at scale demands a systemic approach that optimizes every stage of the power delivery chain, from grid connection to the processor core,” said Magdalene Boebel, Senior Vice President and Business Line Head Power System ICs at Infineon. “Our 24 kW high-voltage BBU reference design, operating directly on an 800 V DC bus, sets a new benchmark in power density and efficiency, giving data center architects a fully integrated solution to meet the most demanding AI infrastructure requirements.”

    The design is based on a multi-level, multiphase non-isolated architecture that combines stacked, interleaved, and coupled boost and buck stages. This architecture reduces magnetic component volume without relying on flying capacitors. A shared switching-leg topology creates a common current path between charge and discharge stages, enabling zero-voltage switching (ZVS) across the operating range.

    According to Infineon, this approach reduces current ripple, supports fully integrated magnetics, and delivers fast transient response capabilities that are increasingly important as AI server power consumption becomes more dynamic and less predictable.

    The compact module measures 112 mm × 88 mm × 118 mm and integrates a 24 kW main power stage together with a 2.4 kW auxiliary power supply. Charger and discharger sections share key components, including the EMI filter, capacitors, and protection MOSFETs, helping to reduce the overall component count. The design also incorporates silicon carbide junction gate field-effect transistors (JFETs) for ORing and hot-swap functionality, while a planar transformer combined with CoolSET™ technology implements the auxiliary switched-mode power supply in a compact footprint.

    At the core of the DC-DC conversion stage is the CoolSiC™ MOSFET IMT65R033M2H, a 650 V device qualified for bidirectional buck-boost DC-DC operation in high-voltage BBU applications. The device’s low conduction and switching losses support conversion-stage efficiencies above 99%, reducing thermal load at rack level.

    During grid disturbances, generator transitions, or power outages, the device enables rapid energy transfer between the HV DC bus and the battery with minimal losses. The IMT65R033M2H features a 650 V breakdown voltage rating, robust body diode, 175°C junction temperature capability, and Infineon’s .XT packaging technology to support operation under voltage spikes, high dv/dt transients, and continuous thermal cycling. Consistent gate-threshold voltage characteristics across devices also simplify multi-phase system design and support redundant rack configurations.

    The architecture is documented in Infineon’s REF_12KW_HFHD_PSU reference design, which demonstrates the use of the IMT65R033M2H in high-power DC-DC stages for rack-level HV BBU applications.

    The complete bill of materials includes CoolSiC 650 V Generation 2 MOSFETs, including the IMT65R033M2H, EiceDRIVER™ gate drivers, TLE497x current sensors, PSOC™ Performance line microcontrollers, CoolSET™ ICs for the auxiliary power supply, and a 1.7 kV SiC MOSFET.

    Additional design features include reduced common-mode noise with negligible AC components and fully integrated magnetics. The design utilizes three power cards that provide mechanical connections for the positive DC, negative DC, and midpoint rails, while also serving as structural elements within the assembly, contributing to the solution’s compact footprint.

    As data center operators move toward higher-voltage DC bus architectures to improve efficiency and reduce power distribution losses, battery backup units are becoming increasingly important for maintaining uninterrupted power delivery to AI servers during grid events. Infineon stated that the 24 kW HV BBU reference design demonstrates how silicon carbide-based DC-DC conversion can address the power density, efficiency, and reliability requirements of next-generation AI infrastructure.

    The company’s broader power portfolio spans silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) technologies, covering power conversion requirements across the entire power delivery chain from the electrical grid to the processor core.
