摘要

介绍了一种磁耦合Buck-Boost双向(MCB3) DC-DC变换器。MCB3变换器是非隔离的DC-DC拓扑结构，具有非反相输出电压和降压升压操作。MCB3变换器中无源元件的配置支持使用三相移(TPS)调制，最初用于众所周知的双有源桥(DAB)变换器。TPS调制使MCB3变换器在任何负载和电压要求下都能使总损耗最小化，就像DAB变换器一样。在整个论文中，给出了所提出的变换器的推导及其在升压模式下的工作原理。从使用TPS调制的三个控制变量得到的操作可能性被确定并用于任何输入要求的功率损失最小化。通过460 W样机的仿真和实验结果，验证了MCB3变换器的可行性，最大效率高于95%。

Non-inverting Magnetically Coupled Buck-Boost Bidirectional DC-DC Converter

The Magnetically Coupled Buck-Boost Bidirectional (MCB3) DC-DC converter is described in this paper. The MCB3 converter is a non-isolated DC-DC topology with non-inverting output voltage and buck-boost operation. The disposition of the passive components in the MCB3 converter supports the use of Triple Phase Shift (TPS) modulation, initially intended for the well-known Dual Active Bridge (DAB) converter. TPS modulation allows the MCB3 converter to overall losses minimization for any load and voltage requirement, as in the cases of the DAB converter. Throughout the paper, the derivation of the proposed converter and its operation is shown for the boost mode. The operation possibilities derived from the use of the three control variables of TPS modulation are identified and used to power losses minimization for any input requirement. MCB3 converter feasibility is demonstrated by showing simulation and experimental results for a 460 W prototype, obtaining a maximum efficiency higher than 95%.
