ABSTRACT:
A DC to DC converter (50, 60, 70) that includes a switching circuit (10) responsive to a DC input, a magnetic amplifier controller (20) responsive to the switching circuit for providing an AC output, and an AC current to DC voltage rectifying circuit (30) responsive to the output of the magnetic amplifier controller for providing a DC output voltage. The magnetic amplifier controller includes a variable inductance (L1) that cooperates with the switching circuit to form a resonant DC to AC inverter (110) that provides to the magnetic amplifier controller a current whose amplitude is controlled by the variable inductance. The magnetic amplifier controller provides an approximately sinusoidal output current which is a function of the current input thereto, and the DC voltage output of the AC current to DC voltage rectifier is a proportional to the input current provided by the magnetic amplifier controller. Thus, the DC voltage output of the DC to DC converter is controlled by the control current to the magnetic amplifier controller.
