Abstract
A motor controller includes a rectifier module, an inverter circuit, an energy storage capacitor C, a DC inductor L, a microprocessor, and a lightning protection and surge protection circuit. The rectifier module includes an output end connected to the energy storage capacitor Cto charge the energy storage capacitor C; two ends of the energy storage capacitor Care connected to the inverter circuit to supply power to the energy storage capacitor C. The DC inductor Lis in series connection between a positive output end A of the rectifier module and a positive end B of the energy storage capacitor C. The lightning protection and surge protection circuit is disposed between the rectifier module and the energy storage capacitor C. The lightning protection and surge protection circuit includes a differential mode protection circuit and a primary common mode protection circuit.
