High-Speed Verification of Power Electronics Circuits! ROHM PLECS Simulator Released

ROHM Co., Ltd. (Headquarters: Kyoto) has released the "ROHM PLECS Simulator" on its official website, allowing power electronics circuit designers and system designers to perform high-speed web-based simulations of ROHM power device operations. This tool is based on the simulation software PLECS®*. The "ROHM PLECS Simulator" enables simulation of losses and temperature rises in a matter of seconds to minutes by selecting power electronics circuit topologies and various ROHM power devices from a list on the website. This significantly reduces the man-hours required for optimal device selection in the early stages of circuit design. Currently, 20 types of topologies have been released, and ROHM plans to expand device models and topologies, including SiC devices, IGBTs, and power modules. This simulator is available for free simply by registering on ROHM's official website. Additionally, a special page provides access to the simulator and necessary information for users (user manual, application notes explaining circuit operation). Features of ROHM PLECS Simulator and how to use it with ROHM Solution Simulator During circuit design, especially for power electronics circuits, simulations are utilized instead of costly and time-consuming hardware prototyping. In 2020, ROHM released the "ROHM Solution Simulator," which allows for batch verification of power device products and IC products, and has been expanding its topologies and device models. It has been highly evaluated for its ability to confirm waveforms close to actual devices with high reproducibility through the provision of high-precision SPICE models. On the other hand, there was a demand in the early stages of development to quickly select optimal power devices based on loss and thermal verification. In response to this demand, ROHM has started offering the "ROHM PLECS Simulator," which specializes in loss and thermal calculations. By using the "ROHM PLECS Simulator" for speedy initial investigations with PLECS® and the "ROHM Solution Simulator" for detailed and high-precision verification, depending on the development phase, a consistent simulation from design loss/thermal verification to waveform checking becomes possible. *) PLECS® A simulator for power electronics circuits and systems developed to model and simulate complex electrical/power systems with control in a virtual space. It excels at high-speed calculations of losses and can quickly verify the response of the entire system in the upstream process of development. PLECS® is a registered trademark of Plexim, Inc.
