Title: Resonance-type dc-dc converter
Inventor: MORITA KOICHI
IPC: H02M3/28
Filed: 1994-03-11
Abstract: PURPOSE:To simplify the circuit constitution of a half bridge type of DC-DC converter being constituted so as to reduce the power loss, using resonance. CONSTITUTION:The series circuit composed of first and second capacitors C1 and C2 and the series circuit composed of first and second switches Q1 and Q2 are connected, respectively, between one end and the other end of a DC power source 1. The primary winding N1 of a transformer T is connected through a first inductance L4 between the mutual junction 3 of the first and second capacitors C1 and C2 and the mutual junction 2 of the first and second switches Q1 and Q2. A second inductance Lp larger in value than the first inductance Lr is connected in parallel with the primary winding N1. Series resonance is caused by the equivalent capacitor consisting of the parallel circuit of the first and second capacitors C1 and C2 and the first inductance Lr. The ON period of the first and second switches Q1 and Q2 is set longer than the half wave of the series resonance. The output voltage is adjusted by changing the ON period of the first and second switches Q1 and Q2.
