摘　　要：提出了一种新型静止无功补偿器,即并联型半桥-磁能恢复开关(HALF-MERS)。给出了HALF-MERS的拓扑结构和基本控制方法,并建立了其数学模型,基于此模型,进一步对HALF-MERS性能进行了分析,讨论确定了HALF-MERS中电感和电容参数的最佳比值。并对HALF-MERS的数学模型及分析结果进行了实验验证。研究结果表明,HALF-MERS以较小的内置电容实现了较大的容性无功补偿,所补偿的无功功率在很大的工作范围内连续可调。同时具有结构简单、能耗少、控制易于实现的特点。This paper improves s new static var compensator—paralleled half bridge configuration of magnetic energy recovery switch（HALF-MERS）.The topological structure and control principle of HALF-MERS is proposed.And the mathematic model of HALF-MERS is also built.Then the performance of HALF-MERS is analysed based on the mathematic model.An optimal value of the parameter of the inductance and capacitance in HALF-MERS is discussed.The mathematic model and and the performance analysis of HALF-MERS is verified by the experiment.Continuously adjustable capacitive reactive power can be obtained from HALF-MERS.And HALF-MERS has the advantages of simple structure,low energy loss and easy control method compared to the MERS of full bridge.
