Using LLC Resonant Converter for Designing Electric Vehicle DC/DC Converter

Article Preview

Abstract:

A design of 100 kHz-1350 W electric vehicle DC/DC converter using LLC resonant converter with integrated transformer is presented. The loss analysis based on theoretical derivation is performed to reveal the loss distribution. Integrated magnetic structure is adopted in the design to further increase the efficiency and power density. A 280 V-360 V input, 13.5 V/100 A output prototype is built to verify its advantage, and the efficiency at 320 V input, 13.5 V/100 A output is 91.5% at the switching frequency of 100 kHz.
