<P>PROBLEM TO BE SOLVED: To provide a system, method, and apparatus to drive reactive loads. <P>SOLUTION: An example apparatus to drive a reactive load includes a reactive component in circuit with the reactive load, a first switching element in circuit with the reactive load to selectively hold the reactive load in a first energy state and to selectively allow the reactive load to change from the first energy state to a second energy state, a second switching element in circuit with the reactive load to selectively hold the reactive load in the second energy state and to selectively allow the reactive load to change from the second energy state to the first energy state, and a controller to detect a current in the reactive load, and to control the first and second switching elements to hold the reactive load in the first or the second energy state when the current exceeds a threshold. <P>COPYRIGHT: (C)2013,JPO&INPIT |
