摘要
Abstract
A single-phase transformerless inverter for photovoltaic power generation is proposed,which has a com-mon ground between its input and output and thus eliminates the common-mode current in the photovoltaic system.Meanwhile,its voltage gain is higher than that of the traditional single-phase quasi-Z-source inverter.In addition,the use of thin film capacitor makes the inverter more reliable and prolongs its service life.The working principle of this inverter is also analyzed in detail.Finally,a 140 W prototype was built,and results verified the correctness of the proposed in-verter topology and the effectiveness of the control strategy in islanding and grid-connected operation modes.关键词
