The trend towards renewable energy sources drives the need for efficient power electronics converters. Applications range from connecting distributed energy sources to the grid to electric propulsion and motion control. The development and testing of controllers for such applications can be time-consuming, expensive, and hazardous when using physical prototypes.
With the real-time simulation of power electronics, you can test power converter controllers faster and more safely, all while ensuring all functional, safety, and certification requirements. Set up such power electronics HIL simulation with Simulink® and Speedgoat, as follows:
