Abstract

PURPOSE:To facilitate a countermeasure against noise by increasing and decreasing the number of ON-OFF pauses for every period corresponding to a second frequency obtained through division by an integer of a first frequency turning ON and OFF a switching element. CONSTITUTION:A load controller periodically turns ON and OFF a switching element 83 provided between a DC power 81 and a load 82 to obtain a high- voltage DC power via a step-up transformer 84, diodes 85-86 and the like. In this case, said switching element 83 is turned ON and OFF with a first frequency f1 and the number of ON-OFF pauses of the switching element 83 for every second period T2 corresponding to a second frequency f2 synchronized with the first frequency f1 and obtained through division by an integer of said first frequency is increased and decreased. Further, the second frequency f2 does not change though said number of pauses varies. Thus, the frequency does not change because an electric energy supplied to the load 82 is controlled, so that a countermeasure against noise can be performed easily.
