ABSTRACT:
A controller for controlling at least two power circuits comprises a pulse generator and a selector. The pulse generator generates a first pulse signal which is coupled to a first power circuit of the at least two power circuits for initiating the operation of the first power circuit. The first power circuit then outputs a second pulse signal to a second power circuit of the at least two power circuits to initiate the operation of the second power circuit. The selector generates a reference signal which is coupled to each of the at least two power circuits for indicating a number of power circuits controlled. The controller is used to control energy supplying to an electrical circuit comprising multiple inverters and is more particularly to provide phase shifts to the electrical circuit. Usually, the electrical circuit is applied to display devices, such as liquid crystal display monitors, liquid crystal display computers and liquid crystal display televisions.
