摘要
介绍了一种采用新型移相控制零电压开关PWM全桥变换器的拓扑结构,研制成75 V/50 A的直流稳压型开关电源。给出了主电路参数的设计方法。这种开关电源与传统开关电源相比,效率高、体积小、重量轻。可靠性好。
This paper introduces a new phase-shifting control of a zero-voltage switching PWM lull-bridge converter topology. The regulators type switching power supply which is with output of 75V/50A DC is developed. The design and calculation methods of parameters in the main circuit have been presented. Compared with traditional has the advantages of high efficiency,small volume, low weight and high reliability.
