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.
Claims14
A circuit for driving a current into an inductor comprising:
- at least one main capacitor;
- a power supply operably connected to said at least one main capacitor;
- said inductor;
- and
- at least two pairs of switches connecting said at least one main capacitor to said inductor whereby the connection of said at least one capacitor to said inductor is made in either polarity, each of said switches having an open position and a closed position.
A method for driving a current into an inductor comprising the steps of:
- applying a current to a main capacitor;
- applying a voltage to said inductor from said main capacitor resulting in generation of inductive energy;
- and
- recapturing said inductive energy with said main capacitor at an end of a cycle, wherein said current and said voltage are measured by a microprocessor which, based upon said measurements, determines when to open and close two pairs of switches connecting said main capacitor to said inductor.
