【Abstract】 The limited double-pole soft-switching control scheme is presented in this paper.this scheme overcomes the disadvantages theoretically that the range of soft switching is limited when the load current is less than a special value in the convenient full-bridge soft-switching schemes,and realizes the soft switching function with all of the loads so as to reduce the energy loss and improve the power density.更多还原
