Parameters Design and Optimum of an Improved ZVS PWM Full-bridge Converter Using a Current Doubler Rectifier

分析了改进型倍流整流电路ZVS PWM全桥变换器的原理,给出了参数选择原则和优化方法,使变换器的主开关管在较宽的负载范围内实现ZVS,副边无占空比丢失,副边整流二极管实现自然换流,无尖峰电压。

An improved ZVS PWM full-bridge converter using a current doubler rectifier is analyzed in this paper. By parameters design and optimum, the converter can achieve ZVS in a wide load range in addition to no lost duty cycle, no voltage spikes.
