ABSTRACT:
A switching regulator includes a first full-wave rectifier for rectifying an input a.c. voltage, at least one power switch connected between the first rectifier and the primary winding of a pulse transformer whose secondary winding is connected through a second full-wave rectifier and a filter to a pair of output terminals across which a regulated d.c. output voltage appears, and a control circuit comprised of a level-shift circuit, a comparator and a pulse width modulator for controlling the on/off condition of the power switch, whereby the pulse width modulator supplies a pulse modulated signal to turn the power switch on only when the comparator supplies a high level signal to the pulse width modulator.
