POWER SUPPLY UTILIZING A HIGH FREQUENCY MAGNETIC AMPLIFIER ABSTRACT A regulated power supply includes an oscillating inverter circuit for generating a high frequency square wave signal that drives a saturable reactor which pulse-width modulates the square wave as a function of a control current through a control winding on the saturable reactor. The output voltage generated by the power supply is sensed by a feedback circuit and fed back as a modulating signal of the control current through the saturable reactor control winding to vary the power transferred by the saturable reactor to an output transformer. The variation in power supplied to the output transformer compensates the output voltage as sensed by the feedback circuit. A protective circuit is provided to sense an output overvoltage condition and inactive the power supply by terminating the oscillation of the inverter.
