摘要:
电压源三相四天关逆变器作为一种故障容错拓扑结构,其负载一相端点接至直流母线中点,利用2个桥臂完成对三相负载线电压的调制。然而在这种拓扑结构下,连接直流母线中点的相电流势必流经上下2只电容,造成电容电压波动。为了尽可能消除由于电容电压波动对调制输出电压造成的影响。文章从输出电压频谱入手分析了造成影响的原因,并且提出了一种新的调制策略来抵消这种波动造成影响。调制方案物理概念清晰,计算简单、方便、可靠,仿真和实验结果验证了分析的正确性和方案的可行性。
Abstract:
As one kind of fault tolerance topology, with one load-phase connecting to the middle point of dc-link, voltage source fourswitch three-phase inverter can generate balanced three-phase voltage by modulating the two bridge-legs. With this topology, the fluctuation will inevitably appear in the DC-link two-capacitor voltages as a result of circulation of one-phase current through the split DC-link voltage sources. To eliminate the fluctuation effect , the reasons were analyzed first from the view of the output voltage spectrum, and an analytical modulation method was then proposed, which not only shows a clear physical conception , but also easy, convenient and reliable computation. The simulation and experiment results validate the correction of analysis and feasibility of the method.
