Abstract

PURPOSE:To improve the conversion efficiency of a conversion transistor by providing a feedback transistor and an exciting transformer, thereby uniformly exciting conversion transistors and preventing the storage time in the conversion transistor from becoming long. CONSTITUTION:A feedback transformer T4 which generates an output voltage in response to a current supplied to main transistors Q1-Q4 is provided. Then, exciting transformers T2, T3 which supply driving currents to transistors Q1-Q4 so that transistors Q1, Q4 and Q2, Q3 forming the sides of the bridge become the same phase and the transistors Q1, Q4 and Q2, Q3 forming the different sides become reverse phase upon supplying of the output voltage of the transformer T4, are provided. With this arrangement, the conversion transistors Q1-Q4 are uniformly excited with the current feedback.
