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 () of a transformer () and a switching circuit () to obtain first and second output direct voltages from a secondary winding () of the transformer () via first and second rectifying circuits, wherein a switching signal of the switching circuit () 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 () is inserted into the second rectifying circuit. Thus, loss of power can be reduced in a simplified configuration.
