ABSTRACT:
A DC-DC convertor includes a transformer having a primary winding adapted to be connected in series with a DC power source and a secondary winding, a rectifier and smoothing circuit, a main switching device, adapted to be connected in series with the DC power source, for connecting the rectifier and smoothing circuit to the secondary winding of the transformer when the main switching device is in an on-state, an auxiliary switching circuit connected in parallel with the main switching device, and a signal generating circuit for providing a first control signal to the main switching device and a second control signal to the auxiliary switching circuit. The auxiliary switching circuit includes a first capacitor connected in parallel with a second capacitor that is connected in series with an auxiliary switching device. The signal generating circuit controls on/off operation of the main switching device and the auxiliary switching device such that both the main switching device and the auxiliary switching device are in an off state simultaneously in a manner wherein the main switching device turns on after a first rest period has elapsed after the auxiliary switching device turns off and the auxiliary switching device turns on after a second rest period has elapsed after the main switching device turns off.
