一种具有恒定关断时间的改进型全桥Boost LCL型DC/DC变换器：分析、设计与实验结果

This article presents a full-bridge boost LCL-type dc/ac/dc converter with an isolation transformer. In the proposed converter, the output voltage is regulated by controlling frequency with a constant turn-off time of the switches. Traditional capacitor works under resonant function so that the dc-bus capacitor is eliminated. Under this design, the converter works under zero voltage switching cond...
