Abstract

PURPOSE: To enable a switching element to be controlled without detecting load voltage, by turning the switching element OFF in a specified delay time after current flowing when the switching element is ON comes to a reference value.
CONSTITUTION: The output of a power source Vs is fed to a load DL via a chopper circuit CHP. Current flowing to an inductance serving as an energy storage element when a switching element on the chopper circuit CHP is ON is detected by a detection means D1, and the detected value is compared with a reference value coming from reference voltage Vr. In a delay time set by a delay circuit DLY after detected current comes to a reference value, the switching element of the chopper circuit CHP is turned OFF.
