<p>A multiple output DC-DC converter which supplies an input dc voltage to the primary winding (3a) of a transformer (3) and the series circuit of a switching circuit (2), and obtains first and second output dc voltages from the secondary winding (3b) of the transformer (3) via first and second rectifying circuits, wherein the switching signal of the switching circuit (2) is controlled according to the first output dc voltage to keep constant the first output dc voltage, and a variable reactor (10) is inserted into the second rectifying circuit to reduce a power loss with a comparatively simple configuration.</p> |
