摘要
作为一种节能高效的直流配电形式,双极性直流母线配电在低压直流配电系统中具有较大的应用优势,电压平衡器在其中扮演着重要的角色。电压平衡器一方面实现了单极性配电向双极性配电的转化,另一方面也解决了正负极性母线间的功率不平衡问题。该文首先分析了现有的电压平衡器拓扑结构研究成果;然后归纳出了电压平衡器的形成方法,提出了Cuk型电压平衡器、Super-Sepic/Zeta型电压平衡器和交错并联Buck/Boost型电压平衡器;最后通过仿真验证了所提出拓扑结构的正确性,通过两相交错并联Buck/Boost型电压平衡器实验平台验证了所提出的交错采样交错平均电流控制策略良好的均流效果和动态响应速度以及平衡器优异的双极性母线配电效果。
As an energy-saving efficient DC distribution form, bipolar DC bus has a great advantage in the low voltage DC power system, in which the voltage balancer plays an important role. A voltage balancer, on the one hand, achieves a conversion from unipolar bus to bipolar bus, and it also solves the problem of power imbalance between positive and negative polarity bus. This paper analyzed the existing research results of voltage balancer topologies in detail, and summed up the method of forming voltage balancers. Furthermore, new topologies were proposed, such as Cuk, Super-Sepic/Zeta and interleaved Buck/Boost type voltage balancers. Finally, the correctness of the proposed topologies were verified by simulations, and two phase interleaved Buck/Boost type voltage balancer experimental platform was used to verify its good bipolar bus distribution effect and the fine current sharing and dynamic characteristic of interleaved average current control strategy.
