onsemi announced a breakthrough in simulation tools for onsemi’s EliteSiC Silicon Carbide (SiC) product family and its applications. The company launched the online Elite Power Simulator and Self-Service PLECS Model Generator, which provide meaningful insights for complex power electronic applications through system-level simulations at an early stage of the development cycle. The tools save power electronic engineers time by providing state-of-the-art accurate simulation data enabling EliteSiC product selection tailored to customer applications, instead of costly and time-consuming hardware fabrication and testing.
Users have ultimate power and flexibility to create high-fidelity system-level PLECS models when the Elite Power Simulator is deployed in conjunction with the Self-Service PLECS Model Generator. Whether uploaded to onsemi’s Elite Power Simulator or downloaded for direct use, the self-service PLECS models deliver the optimization and accuracy required for demanding power electronic simulations. The models are generated based on typical or worst-case conditions to let the customer design within the technology boundaries. The capability to define application-specific parasitics ensures that the generated PLECS models provide highly accurate results for the customer’s system-level simulations.
“Our PLECS simulator has proven very popular with power designers due to speed and ease of use,” said Jost Allmelling, managing director and co-founder, Plexim. “It is particularly exciting to see the truly novel aspects here, including the ability to simulate soft switching accurately, the customized models via the onsemi Self-Service PLECS Model Generator and the ready-made models for corner cases.”
To date, system-level simulators and their associated PLECS models have only been valid for hard switching topologies, with simulation results for soft switching applications such as LLC (inductor-inductor-capacitor) or CLLC (capacitor-inductor-inductor-capacitor) being highly inaccurate. onsemi’s industry-first PLECS models break this trend and solve this problem for customers.
“This is a significant step for the industry, increasing its ability to get both hard and soft switching designs to market quickly,” said Asif Jakwani, senior vice president and general manager of the Advanced Power Division, which is part of the Power Solutions Group at onsemi. “Our tools enable our customers to understand how our devices perform in their application environment and fully optimize the performance within the boundaries of the technology.”

While the adoption of GaN devices has expanded in recent years due to their superior high-speed switching characteristics, the speed of Control ICs, which are responsible for directing the driving of these devices, has become challenging.
In response, ROHM has further evolved its ultra-high-speed pulse control technology Nano Pulse Control™. It is cultivated for power supply ICs, succeeding in significantly improving the control pulse width from the conventional 9ns to an industry-best 2ns. Leveraging this technology allowed ROHM to establish its ultra-high-speed Control IC technology that maximizes the performance of GaN devices.
When pursuing miniaturization of the power supply circuit, it is necessary to reduce the size of the peripheral components through high-speed switching. Achieving this requires a Control IC that can take advantage of the drive performance of high-speed switching devices such as GaN devices.
To propose solutions that include peripheral components, ROHM established ultra-high-speed Control IC technology optimized for GaN devices utilizing proprietary analog power supply technology Nano Pulse Control™.
ROHM is currently working to commercialize Control ICs utilizing this technology, with plans to start sample shipment of 100V 1ch DC-DC Control IC in the second half of 2023. Using in conjunction with ROHM GaN devices (EcoGaN™ series) is expected to result in significant energy savings and miniaturization in a variety of applications, including base stations, data centers, FA (Factory Automation) equipment, and drones.
Going forward, ROHM will continue to develop products that solve social issues by pursuing greater ease-of-use in applications centered on its strengths in analog technology.
