PROBLEM TO BE SOLVED: To provide a DC/DC converter capable of lowering a voltage related to a switching means.SOLUTION: In a primary circuit of an input-side transformer, switching means Q1 to Q4 are arranged in a bridge formation, of which opposed two sides are provided with capacitors C1 and C2 arranged in series to the switching means Q3 and Q4, respectively. The capacitors C1 and C2 clamp a transformer inter-terminal voltage when the switching means Q1 and Q2 are off, and limits a duty (= on time Ton/(on time Ton+off time Toff)) when the switching means Q1 and Q2 are switched on and off. |
