An Integrated Boost-Inverter with No leakage Current

Traditional inverter is a buck type converter, and the two-stage inverter with a boost converter is too complex. For suiting for a wide input voltage rang, this paper proposes a integrated boost-inverter. The proposed boost-inverter integrates a boost conveter without adding extra power switches. It can realize the boost function and buck function. Moreover, its negative pole of DC input source and AC output voltage is connected directly, which eliminates the high-frequency leakage current of both DC side and AC side. The theory of the proposed boost-inverter is explained, and the experiment is buildup to verified that the the proposed inverter is correctly and available.
