From the developer:
PLECS facilitates the modeling and simulation of complete systems, including power sources, power converters, and loads. Included with PLECS is a comprehensive component library, which covers the electrical, as well as the magnetic, thermal, and mechanical aspects of power conversion systems and their controls. Power electronics circuits are captured with a schematic editor in a way that is familiar and intuitive for electrical engineers.
