Abstract

A novel high frequency auxiliary converter was developed, which consisted of BuckTL converter, LLC DC/DC converter, three phase inverter and half-bridge DC/DC converter. The main circuit structure of each component was described, as well as its working principle and modes, and the key parameters design method. The results of simulation and test showed that the auxiliary converter had a good performance, which increased the power density greatly.
