Abstract :
A small size and high efficiency base drive scheme using a high frequency partial resonant converter with zero voltage switching (ZVS) is proposed. By using this base drive, the performance of switching power transistors is enhanced to some extent because the transistor can be lightly saturated in accordance with the load condition owing to easy control capability of transistor base current
