Comparing with the counterparts, the novel inverter has larger current transfer gain with smooth waveforms. The simulation process is manipulated on the basis of the state-space averaging approach. The power transfer efficiency is studied in detail. Finally. the theoretical analysis is verified with the simulative and testing results.展开更多
