摘要: A neutral-point-clamped (NPC) three-level inverter is used more and in the grid-connected power generation system. In order to achieve lower current harmonic, an LCL filter widely utilized due its superior filtering performance. Passive active damping control are studied solve resonant problem appearing filter, overcomes weakness of loss existing passive method, thus it gradually becomes one research focus. According feature NPC method based on feedback capacitor current, design thoroughly discussed this paper, simulation experimental results show that right.
