一种中小功率的高频开关式通信电源的设计

Moderate and Small Communications Power Based on High Frequency and Switch Mode

针对通信电源中DC/DC变换器的移相全桥主电路进行了分析和研究,在此基础上提出了采用改进型倍流整流移相全桥电路,来克服传统ZVS PWM全桥变换器存在的一些问题。

This paper analyses and studies PSFB circuit, which is the main circuit of DC/DC converter of communications power supply.According to the characteristic of PSFB circuit.The paper proposes the ZVS PWM Current Doubler Rectifier topology to overcome the shortage of full wave rectifier.
