ROHM Launches PLECS Simulator for Faster Power Electronics Design
Event summary
- ROHM Semiconductor released the ROHM PLECS Simulator on May 28, 2026, enabling rapid power electronics circuit verification.
- The tool specializes in loss and thermal calculations, reducing device selection time from hours to seconds.
- Twenty topologies are available, with plans to expand to SiC devices, IGBTs, and power modules.
- The simulator is free to use after user registration on ROHM’s website.
The big picture
ROHM’s PLECS Simulator addresses a critical pain point in power electronics design: the need for rapid, cost-effective prototyping. As the industry shifts toward higher efficiency and faster development cycles, tools that reduce time-to-market for power devices will gain traction. This move positions ROHM as a leader in design enablement, potentially attracting more customers to its power semiconductor portfolio.
