Abstract:According to the requirement of grid-connected inverter whose tendency is light weight and isolation,this paper proposes a novel high frequency link inverter using combination tow rectifiers. The control scheme and main waveforms of the proposed inverter are given and the working mode is analyzed. According to the results of the Fourier decomposition of the input voltage of transformer and output voltage of the inverter,it can be shown that the transformer works in high frequency and sinusoidal voltage can be easily obtained through LC filter. The advantage and disadvantage of proposed inverter are obtained after comparing with uni-polarity inverter with conventional high frequency pulse AC link. The experimental results verify that the performance of proposed inverter is excellent and it can be used as grid-connected inverter.
