Three-phase inverter overvoltage standard

Three-phase inverter reference design for 200-480VAC

This reference design is a three-phase inverter drive for controlling AC and Servo motors. It comprises of two boards: a power stage module and a control module.

Inverter Ground Fault Overvoltage Testing

The GFO tests were completed on three commercial inverters: a single-stage, three-phase string inverter; a dual-stage, three-phase string inverter, and a three-phase assembly of single-phase
