    2 Min Read

    Infineon Technologies AG introduced the 600 V CoolMOS™ 8 high voltage superjunction (SJ) MOSFET product family. The devices combine the best features of the 600 V CoolMOS 7 MOSFET series and are the successors to the P7, PFD7, C7, CFD7, G7 and S7 product families. The new superjunction MOSFETs enable cost-effective Si-based solutions that enhance Infineon’s wide-bandgap offering. They are equipped with an integrated fast body diode, making them suitable for a wide range of applications such as server and industrial switched-mode power supply units (SMPS), EV chargers, and micro-solar.

    The components come in SMD QDPAK, TOLL and ThinTOLL 8 x 8 packages, which simplifies designs and reduces assembly costs. At 10 V, the 600 V CoolMOS 8 SJ MOSFETs offer 18 percent lower gate charge (Q g) than the CFD7 and 33 percent lower than the P7. At 400 V, the product family offers a 50 percent lower output capacitance C OSS than the CFD7 and the P7.

    In addition, the turn-off losses (E oss) have been reduced by 12 percent compared to the CFD7 and the P7 and the reverse recovery charge (Q rr) is 3 percent lower compared to the CFD7. Furthermore, the devices offer the lowest reverse recovery time (t rr) on the market and the thermal performance has been improved by 14 to 42 percent compared to the previous generation.

    With these features, the devices offer high efficiency and reliability in soft-switching topologies such as LLC and ZVS phase-shift full-bridge. They also provide excellent performance levels in PFC, TTF and other hard-switching topologies. Due to their optimized R DS(on), the devices offer higher power density, allowing products in a Si-based super junction (SJ) technology to be reduced to a single-digit value of 7 mΩ.

    Infineon will showcase the 600 V CoolMOS 8 SJ MOSFETs at the Infineon booth (Hall 7 / Booth 470) at PCIM 2024 in Nuremberg. Samples of the 600 V CoolMOS 8 SJ MOSFETs are now available. More information is at www.infineon.com/coolmos8.

    Navitas Semiconductor announced their new portfolio of Gen-3 ‘Fast’ (G3F) 650 V and 1,200 V SiC MOSFETs optimized for fastest switching speed, highest efficiency, and increased power density for applications such as AI data center power supplies, on-board chargers (OBCs), fast EV roadside super-chargers, and solar / energy-storage systems (ESS). The broad portfolio range covers industry-standard packages from D2PAK-7 to TO-247-4, designed for demanding, high-power, high-reliability applications.

    The G3F family is optimized for high-speed switching performance, resulting in 40% improvement to hard-switching figures-of-merits (FOMs) compared to competition in CCM TPPFC systems. This will enable increasing the wattage of next-generation AI power supply units (PSUs) up to 10 kW, and power per rack increase from 30 kW to 100-120 kW.

    The G3F GeneSiC MOSFETs  are developed using a proprietary ‘trench-assisted planar’ technology.  and offer better-than-trench MOSFET performance, while also providing superior robustness, manufacturability and cost than competition. G3F MOSFETs deliver high-efficiency with high-speed performance, enabling up to 25°C lower case temperature, and up to 3x longer life than SiC products from other vendors.

    The ‘trench-assisted planar’ technology enables an extremely low RDS(ON) increase versus temperature, which results in the lowest power losses across the complete operating range and offers up to 20% lower RDS(ON) under real-life operation  at high temperatures compared to competition.

    Additionally, all GeneSiC MOSFETs have the highest-published 100%-tested avalanche capability, 30% longer short-circuit withstand time, and tight threshold voltage distributions for easy paralleling, GeneSiC MOSFETs are ideal for high-power, fast-time-to-market applications.

    Navitas’ latest 4.5 kW high-power density AI Server PSU reference design in CRPS185 form-factor, showcases the 650 V-rated, 40mOhms G3F FETs for an Interleaved CCM TP PFC topology. Alongside the GaNSafe™ Power ICs in the LLC stage, a power density of 138 W/inch3 and peak efficiency above 97% is realized, which comfortably achieves ‘Titanium Plus’ efficiency standards, now mandatory in Europe.

    For the EV market, 1,200 V/34 mOhm (G3F34MT12K) G3F FETs enable Navitas’ new 22 kW, 800V Bi-Directional OBC and 3KW DC-DC converter to achieve a superior power density of 3,5 kW/L and a peak efficiency of 95.5%.

    “G3F sets a new standard for efficient, cool-running SiC performance, coupled with high reliability and robustness for high-power, high-stress systems,” noted Dr. Sid Sundaresan, Senior Vice President of SiC Technology and Operations. “We’re pushing the boundaries of SiC, with up to 600 kHz switching speeds, and hard-switching figures-of-merit up to 40% better than competition.”

  • Cambridge GaN Devices and Qorvo® Partner to Develop a Reference Design and Evaluation Kit for Motor Control

    Cambridge GaN Devices and Qorvo® Partner to Develop a Reference Design and Evaluation Kit for Motor Control

    3 Min Read

    Cambridge GaN Devices is partnering with Qorvo® to develop a reference design and evaluation kit (EVK) that showcases GaN for motor control applications. CGD aims to speed the use of GaN power ICs in BLDC and PMSM applications, resulting in higher power, highly efficient, compact and reliable systems. Qorvo is building an EVK for its PAC5556A motor/control IC that is powered by CGD’s ICeGaN™ (IC-enhanced GaN) technology.

    GIORGIA LONGOBARDI | CEO, CGD
    “Because ICeGaN – unlike other GaN implementations from other companies – integrates the interface circuitry but not the controller together with the GaN HEMT, it is simple to combine with highly integrated motor controller and drive ICs such as Qorvo’s PAC5556A 600 V High Performance BLDC / PMSM Motor Controller and Driver. We are delighted to partner with Qorvo to enable motor controller and driver applications to enjoy the benefits of GaN power.”

    JEFF STRANG | GENERAL MANAGER, POWER MANAGEMENT BUSINESS UNIT, QORVO
    “Wide bandgap semiconductors such as GaN and SiC are being actively considered in various motor control applications for the power density and efficiency benefits they bring. CGD’s ICeGaN technology offers ease of use and reliability, two crucial factors for motor control and drive designers. We are excited to see the reaction of design engineers when they experience the power of GaN combined with our highly integrated PAC5556A 600V BLDC motor control solution.”

    GaN brings a variety of benefits, primarily lower losses, which results in higher efficiency, leading to increased power availability and less heat. This reduces the need for complex, bulky, and costly thermal management solutions, resulting in smaller, more powerful systems that have a longer life. GaN also delivers higher torque at low speeds and, therefore, more accurate control. Also, GaN allows high-speed switching, which can reduce audible noise, which is especially valued for domestic items such as ceiling fans, heat pumps, and refrigerators.

    In addition to being easy to use, ICeGaN offers several other significant benefits over other GaN devices. The gate drive voltage of ICeGaN is compatible with IGBTs. Because ICeGaN integrates the Miller clamp within the GaN IC, a negative Turn-Off voltage is not required, and low-cost current drivers can be used. Finally, ICeGaN includes a useful current sense function, simplifying circuit design and reducing BOM.

    The reference design is available today, and EVK RD5556GaN will be available for purchase in Q324. It will also be shown on CGD’s booth Hall 7 643 at the PCIM exhibition in Nuremberg, Germany, 11-13 June. Qorvo will also exhibit at PCIM, on booth Hall 7 406.

Applicable to many critical applications such as xEV charging, solar inverters, and industrial power supplies, the new package selections give designers the added flexibility of multiple system optimization options to further maximize system efficiency while streamlining their manufacturing process.

    AOS will showcase its expanded surface mount and module package options at PCIM Europe 2024 in Nuremberg, Germany, June 11-13.

    The first new surface mount package is available for the AOBB040V120X2Q, AOS’ new 1200V/40mOhm αSiC MOSFET in a standard D2PAK-7L surface mount package. This AEC-Q101 qualified product is designed to replace traditional through-hole packages. It is ideal for applications such as on-board chargers (OBCs) where efficient cooling can be provided by vias and backside PCB heatsinks, simplifying the assembly flow and maximizing the power density. In addition, the low inductance package combined with the fast driver sourcesense connection positions these AOS αSiC MOSFETs as one of the most efficient power-switching solutions in the market.

    For additional design flexibility, AOS is releasing its GTPAK™ surface mount package with topside cooling features. In designs where a topside-mounted heatsink is viable, the direct heat path from the GTPAK minimizes the thermal resistance. It enables higher power dissipation for more effective PCB routing. The first AOS product in GTPAK is the AOGT020V120X2. This 1200V/20mOhm αSiC MOSFET is an ideal solution to meet the requirements of high-efficiency solar inverter and industrial power supply applications.

    Finally, AOS announced the AOH010V120AM2 as the first product in its new AlphaModule™ high power baseplate-less module family. This 1200V/10mOhm half-bridge αSiC module features press-fit pins and an integrated thermistor. It is in a standard footprint module that enables the replacement of multiple discrete devices into a single compact form factor while simplifying both the mechanical and electrical design by providing a clear separation of electrical and cooling paths. Single modules are suitable for residential solar inverters, or several modules in parallel will allow scaling to power levels necessary to drive the needs of fast DC charging stations.

    “With the continued growth in EVs, energy infrastructure, and renewable energy, we continue to see increased interest in our αSiC MOSFETs. The expansion of our product portfolio to include these new advanced package options gives our customers the design flexibility they need to take advantage of our superior αSiC performance and continue the trend of pushing power systems to higher density and efficiency,” said David Sheridan, Vice President of SiC products at AOS.
