Abstract

PURPOSE:To reduce the switching loss by providing two parallel resonance type invertor having constant frequency and switching frequency and controlling the phase angle based on a output voltage. CONSTITUTION:A DC/DC converter is constituted of a reference parallel resonance type invertor 17 and a transformer 4 connected thereto, a parallel resonance type inverter 18 for controlling and a transformer 14 connected thereto, a rectifier output filter 19, a voltage detection circuit 21 and a reference voltage circuit 22 and an error lamp 23 in an error detection section 20, and a phase control section 24. The control section 24 is constituted of a pulse generator 25, a saw tooth wave generator 26, a comparator 27 and flip flops 28-29, and a driving signal is outputted. The outputs of two synthesized parallel resonance type invertors can be controlled selectively by each phase difference, and the stable DC voltage can be supplied to a load 11 by rectifying it.
