Leakage current reduction of Z-source four-leg inverter for transformerless pvsystem

Abstract

The leakage current reduction is one of the most important issues for transformerless PV systems. The conventional Z-source three-phase PV inverter failed to suppress the leakage current in an effective way. In order to solve the problem, a new modulation strategy for the Z-Source four-leg transformerless PV inverter is proposed in this paper. The common… (More)
