Abstract

PURPOSE: To prevent the sequential break-down through permitting a photo-coupler to be actuated, blocking a drive circuit and cutting a switch transistor by detecting the overoltage by a zener diode in the event that the voltage of the input power source may be higher than a predetermined value.
