摘要(Abstract)：

占空比加双重移相控制下的交错并联Buck-Boost和双有源全桥集成的三端口变换器功率密度高、工作方式灵活、应用广泛，但是由于控制方式较为复杂，回流功率高也成为其发展的瓶颈。针对该集成型三端口变换器工作过程中存在的功率回流问题，分析了回流功率产生原理，建立了此变换器传输功率与回流功率数学模型，得到了回流功率与占空比和移相占空比的关系方程；基于此方程，采用模拟退火粒子群算法对占空比与移相角进行优化。通过运行工况为输入电压100 V、输出电压48 V、开关频率20 kHz的仿真与实验结果表明：所提方法可以实现减小回流功率的目标回流功率减少近13%，与模拟退火算法相比，该方法使集成型三端口变换器的回流功率明显降低。
