ABSTRACT:
A switching power supply has a power switching transistor furnishing a series of shaped pulses to output means for providing an output voltage, has control means including a voltage controlled oscillator responsive to the output voltage for providing control pulses whose frequency is representative of the output voltage level, and has saturable transformer means coupling the control pulses to the switching transistor for driving the transistor to regulate the output voltage within a selected range. First winding means on the saturable transformer drive the transformer to saturation with each control pulse and other winding means forward bias the switching transistor to conduct while the transformer is being driven to saturation and thereafter reverse bias the transistor to rapidly turn it off as the transformer recovers from saturation. The power supply includes means for varying transistor switching frequency and pulse width for regulating output voltage.
