Abstract
Optimal techniques for power supply with transient current circuit are introduced in this paper. The circuit reduces switching loss of buck converter´s main switch effectively. However, in our previous researches, it could be operated with high efficiency only at heavy loading. The techniques to get rid of this disadvantage are proposed and the validity of it is verified through experiments.
