International ClassH02M 003/28AbstractA 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.Field of SearchWith automatic control of the magnitude of output voltage or currentWith inductive control means in the line circuit Saturable reactor (e.g., magnetic amplifier) In plural phase to D.C. system With plural control windings With electronic tube or a three or more terminal semiconductive device in control circuit | |
