移相全桥ZVZCS变换器潜电路的研究及分析

Research on Sneak Circuits in the ZVZCS Phase-shifted Full-bridge Converter

针对零电压零电流移相全桥ZVZCS变换器中出现的潜在电路,使用图论分析法,去除无效冗余和正常工作的电路模态,进而得到变换器中所有潜电路模态,并且利用Matlab/simulink搭建电路进行仿真验证分析的正确性。

Aiming at the sneak circuits in zero-voltage and zero-current phase-shifted full-bridge converter ZVZCS, this paper, by using graph theory analysis method to remove the invalid redundancy and the normal work circuit mode, gets the sneak circuit mode of the converter. Then the circuit simulation is carried out by Matlab/simulink to verify the correctness of the analysis.
