Abstract

PURPOSE:To maintain an ideal resonance condition in a wide range by a method wherein a resonance capacitor is connected to the A.C. side and also to the D.C. side. CONSTITUTION:An invertor 3 is composed of switching elements Q1, Q2 which repeat switching in a certain period and a transformer T. A rectifier D, and wave filters CL, LL are connected to the output side of the invertor to constitute a DC-DC converter. In addition, a capacitor Ci is connected to an input power source side in parallel with the inverter. Then a capacitor Co that reaches an oscillating state with the leakage inductance of the transformer T, etc. is connected to the output side of the invertor between the rectifier D and the wave filters CL, LL. An ideal resonance condition can be maintained in a wide range, while the occurrence of an output ripple and noise can be prevented.
