Research and Design of Auxiliary Power Supply for Motor Controller in Electric Vehicles

Abstract:

For the electric vehicle motor controller driver section requirements of the multiple isolated power supply problems, analyzed the common DC/DC converter, the single-ended flyback converter was selected as the motor controller auxiliary power supply. Taking into account the parasitic parameters of the high frequency transformer and switch transistor effects on the circuit, the loss model was showed. Its feasibility is verified by experiments. Experimental results showed that the designed RCD clamp circuit switch could effectively reduce stress and meet the requirements of the motor controller.
