ABSTRACT:
A DC to DC converter has a transformer with a highly coupled primary and secondary, a first switch connected in series between a current source and the primary, a second switch connected across the current source in parallel with the first switch and the primary, a rectifier connected to rectify the output of the secondary, an energy storage device such as a capacitor connected to receive the output from the rectifier, and a load connected to receive output voltage across the capacitor. The current source which provides the substantially constant current can be a superconducting storage magnet. The first and second switches are controlled to alternately open and close to provide current through the primary of the transformer to recharge the energy storage device. When voltage across the energy storage capacitor reaches a minimum level, the one of the first and second switches which was closed is opened and the other is closed. This cycle is repeated as the voltage across the output capacitor reaches the minimum value to maintain the output voltage substantially at a constant level.
