摘要： A method and system are disclosed for controlling electrical current through an inductive load. The electrical current is supplied by one of at least three selectable dual capacitor bank electrical circuits. The method includes storing electrical energy during a charge operating state in first and second capacitor banks of a first dual capacitor bank circuit. The stored electrical energy is then used to drive the inductive load when operating the first dual capacitor bank circuit in a drive operating state. After depleting the stored electrical energy from the first and second capacitor banks, the first dual capacitor bank transitions to a collection operating state that includes collecting electrical energy from the inductive load. A second and third dual capacitor circuits simultaneously transition among the charge operating state, the drive operating state, and the collection operating state during operation.
