The induced model was stable and the mortality rate was acceptable. In the 60 mg/kg, day cyelophosphamide group, the T level and T/LH ratio had no significant change (P ＞ 0.05 ), and the concentration of MDA ,number of Leydig' s cell and layers of spermatogenetic epithelia recovered at 30th day after induction.

A novel zero-voltage and zero-current resonant pole soft-switching inverter was proposed to achieve zero- voltage and zero-current switching simultaneously when main power devices turn-on and turn-off. Therefore, turn-on capacitive losses could be reduced for devices which the intrinsic capacitor value cannot be neglected. Additionally losses caused by the tail current can also be reduced, when IGBTs are used as main switches.
