ABSTRACT:
A circuit for regulating the output voltage of a switched mode power supply having a current mode magnetic amplifier includes a current transformer for sensing current flow through the magnetic amplifier. The sensed current is provided to a circuit which includes a resistor for developing a pulsating voltage and a storage capacitor for converting the pulsating voltage to a tracking voltage and storing the tracking voltage. The tracking voltage and a reference voltage are provided to a differential amplifier, the output of which operates a transistor which controls the operation of the magnetic amplifier, thereby regulating the output voltage of the power supply.
