電源装置
Document Type and Number:
Japanese Patent JP5652969
Kind Code:
B2
Abstract:
An electric power supply apparatus, which enables a driving frequency of a switching circuit connected to a primary side of a transformer constant and output of a secondary side variable, comprises a transformer (5), a series circuit of two first switching elements (Q1, Q2) connected between terminals of a direct current power supply (2), an LC resonant circuit connected between both ends of one of the first switch element (Q2) and a primary winding (Np) of the transformer (5), bidirectional switch elements (Q3, Q4) connected to secondary windings (Ns1, Ns2) of the transformer (5) and having a rectification function and a phase control function, and a control circuit for inputting gate driving signals having a phase difference into the first switch elements (Q1, Q2) and the second switch elements (Q3, Q4).
