ABSTRACT:
A DC-DC converter for supplying DC power to a load comprises a transformer, a switch, a current detector, a bias voltage adjusting circuit, and a control element for the OFF control of the switch. The transformer has primary and secondary windings for supplying power to the load and also a tertiary winding for driving the switch. The control element is controlled by sum of the variable bias voltage obtained from the bias voltage adjusting circuit and the current detection voltage obtained from the current detector. The switch is converted from the ON state into the OFF state when the control element is turned on.
