摘要

双向DC-DC变换器在混合动力汽车、太阳能逆变器、微处理器电源等方面有着广泛的应用。双向dc-dc变换器可以在能量流的一个方向上交替工作为降压变换器，在能量流的反方向上交替工作为升压变换器，即从源到负载和负载到源。使用单个变换器的高电源不可取，因为它会导致输出电压和电流的高纹波，从而需要大值的电感和滤波电容。为了克服这些限制，在双向DC-DC变换器中使用多相交错技术，即将变换器并联并均匀分布在它们之间的开关瞬间。本文介绍了两相双向dc-dc变换器的仿真与实现。

Design, simulation and implementation of two phase interleaved bi-directional DC-DC converter

The bi-directional DC-DC converter has many applications, such as in hybrid vehicles, solar inverters, in power supplies for microprocessors etc. A bi-directional dc-dc converter can be alternately operated as a step down converter in one direction of energy flow and as step up converter in reverse direction of energy flow, which is from source to load and load to source. A high power supply using a single converter is not preferred as it leads to high ripple in output voltage and current, thus requiring large value of inductor and filter capacitor. To overcome these limitations multiphase interleaving technique is used in bi-directional DC-DC converters i.e. connecting the converters in parallel with the switching instants equally distributed among them. This paper presents the simulation and implementation of two phase bi-directional dc-dc converter.
