摘要
详细介绍了移相全桥型零电压软开关的工作原理。然后,采用移相全桥技术设计了一台单相交流输入220V,输出20A、5V^48V的电源样机,并给出试验结果,该电源效率达到90%。
The paper introduces the principle of phase-shift full-bridge zero-voltage-switching PWM converter.A power supply that input sp(single phase)220V/50Hz AC and output 20A/(5V~48V) DC is designed by use of phase-shift full-bridge.The efficiency of the power supply can even reach 90%.
