摘要
移相式双向DC-DC变换器(Bi-directionalDC-DCConverter,BDC)是BDC的基本拓扑之一。文章研究了移相式BDC的调压工作原理和输入输出电压变比、移相角对其环流能量的影响,并进行了仿真验证,指出移相式BDC方案不适于宽调压范围应用。结合移相式BDC的工作原理,把推挽正激电路应用在移相式BDC场合,并进行了试验验证。
The phase-shifted Bi-directional DC-DC Converter(BDC)is one of the elementary topologies BDC. The freewheeling energy from output to input is very large, which is the main drawback in the phase-shifted BDC. The phase shifted angle and the voltage ratio of input and output is the main effected facts. The effected facts of the freewheeling energy are proposed in the paper, and the simulation verified the analysis. The push-pull forward topology is applied in the phase-shifted situation. A prototype is proposed.
