onsemi's new online system level simulator allows power electronic engineers to virtually test and validate onsemi's complete Silicon-Carbide (SiC) lineup through an expansive library of customizable circuit topologies. Ultimate power is given to the user when the simulator is deployed in conjunction with advanced PLECS models where the user can control system parasitics. The simulator and PLECS models provide meaningful insights at an early stage of the power application development cycle through simulation instead of hardware fabrication and testing.
