ABSTRACT:
A circuit for regulation of a D.C. output voltage in a switching power supply. The circuit contains a control transformer having primary, secondary and control windings. The output of the circuit is connected from the primary and secondary windings and is controlled by a switching element connected from the control winding. The circuit output error is provided to duty cycle modulation circuitry which varies the duty cycle of the switching element, thereby controlling the output voltage level.
