PURPOSE:To prevent a power conversion transformer from irregularly magnetizing due to irregular conducting time of a transistor by independently composing two rectifying and smoothing circuits at the secondary side. CONSTITUTION:A full-bridge type DC/DC converter has DC input terminals 1, 2, a capacitor C1 connected between the terminals 1 and 2, transistors Q1-Q4 forming a bridge, a capacitor C2, and a transformer T1. DC power applied between the input terminals 1 and 1 alternately conduct and interrupt the transistors Q1, Q4 and Q2, Q3, is converted to AC power, which is outputted from the secondary coil of a transformer T1, rectified by diodes D1-D4, smoothed by choke coils L1, L2 and capacitor C3, and outputted from terminals 3, 4. |
