However, thereexists aproblem of thiskindofconverter, thatthe output rectifier diodessuffer theparasitic
4、 oscillation and voltage spike resulted by the reverse recovery of the rectifier diodes. In this paper, a novel ZVSconverter is proposed which adopts two clamping diodes in the first side of transformer, thus the parasitic oscillation andvoltagespike are eliminated. The operation principle of thenov
