ABSTRACT:
The present invention provides a multi-output DC-DC converter which supplies an input direct voltage to a series circuit consisting of a primary winding (3a) of a transformer (3) and a switching circuit (2) to obtain first and second output direct voltages from a secondary winding (3b) of the transformer (3) via first and second rectifying circuits, wherein a switching signal of the switching circuit (2) is controlled corresponding to the first output direct voltage so that the first output direct voltage is caused to be constant, and a variable reactor (10) is inserted into the second rectifying circuit. Thus, loss of power can be reduced in a simplified configuration.
