三通道交错并联双向Buck-Boost变换器：高效能量双向流动与精准控制,三通道交错并联双向Buck-Boost变换器：高效能量双向流动与减小电感电流纹波的研究,三通道交错并联双向buck-boost变器。通过simulink搭建的三通道交错并联双向buck-boost变器，采用电压外环，三电流内环，载波移相120°的控制方式。在buck模式与boost模式互相切之间，不会产生过压与过流，实现了能量双向流动。且交错并联的拓补结构，可以减少电感电流的纹波，减小每相电感的体积，提高电路的响应速度。该拓补可以用于储能系统中。整个仿真全部离散化，采用离散解析器，主电路与控制部分以不同的步长运行，更加贴合实际,控制与采样环节全部自己手工搭建，没有采用Matlab自带的模块。,核心关键词：三通道交错并联;
