ABSTRACT:
An asymmetrical duty cycle flyback converter comprising a main transformer for transforming an input voltage at a desired ratio, the main transformer including a primary winding connected to an input stage and a secondary winding connected to an output stage, a switching circuit for switching the input voltage to the main transformer, the switching circuit including first and second switches, a rectifying/smoothing circuit for rectifying and smoothing an output voltage from the main transformer, a controller for generating a control signal in response to an output voltage from the rectifying/smoothing circuit to control the switching operation of the switching circuit, and a switch driver for generating first and second drive signals in response to the control signal from the controller to drive the first and second switches in the switching circuit in such a manner that they can complementarily be switched on the basis of on-time duties asymmetrical with respect to each other and at an interval of a dead time therebetween to perform a zero voltage switching operation. With this construction, the present invention has the effect of realizing a miniaturation and improvement in power efficiency.
