摘要
简要介绍两种隔离式DC/DC变换器次级整流电路的电路特点。以半桥拓扑作为初级电路,从输出电流纹波、滤波电感损耗以及变压器损耗等方面对中心抽头电路和倍流整流电路进行详细比较,总结各自的优缺点。得出中心抽头电路适用于输出电流较低的场合,倍流整流电路适用于低压大电流的场合。
The circuit characters of two isolated DC/DC converter secondary rectifiers are introduced in this paper. When the half bridge topology is selected, comparison of the center tapped rectifier and the current doubler rectifier is proposed in five different specifications such as output current ripple, loss of filter inductions and transformers. The advantages and disadvantages of each topology are presented. The center tapped rectifier is more adapt to low output current application, and the current doubler rectifier is more adapt to low -voltage high-current application.
