Abstract

In this paper, the LCLC resonant converter with zero current switching (ZCS) and zero voltage switching (ZVS) is investigated for two-stage high-voltage (several kilovolts) high-frequency (several hundred kilohertzes) applications. The working principles of the LCLC resonant converter with ZCS and ZVS are explained and the equivalent circuit of each mode is established. In addition, based on the working principles, design equations are deduced. Simulations in PSIM and MATLAB support the analysis. An LCLC resonant converter with 40-V input, 4800-V output, 500-kHz switching frequency, 295-W output power, and 96.8% efficiency is presented and the experimental results validate the analysis.
