Abstract
A circuit for driving a current into an inductor, which circuit includes at least one main capacitor, a power supply operably connected to the main capacitor, the inductor, and at least two pairs of switches connecting the main capacitor to the inductor, whereby the connection of the main capacitor to the inductor is made in either polarity. Current is driven into the inductor by applying a current to the main capacitor, applying a voltage to the inductor from the main capacitor resulting in generation of inductive energy, and recapturing the inductive energy with the main capacitor at the end of a cycle.
