摘要：
In this paper, a high frequency link, single stage, three phase DC-AC converter topology is proposed. The converter is suitable for applications like grid integration of photovoltaic, fuel cell where power flow is mainly unidirectional. The DC side of the converter is fully soft-switched (zero voltage switched). The AC side of the converter is line frequency switched. The use of high frequency transformer (HFT) helps to achieve high power density by reducing the size of the magnetics. A small shunt compensator is used at the grid end to ensure the unity power factor operation of the converter. A detail analysis of the converter operation is discussed in this paper. Important simulation results verifying the converter operation are also presented.
