Abstract

PURPOSE:To prevent a large current flowing in a transistor by a method wherein a transformer is attached to a rear stage of a choke coil so that the current flowing into a switch is controlled by the choke coil. CONSTITUTION:A transformer T2 is attached to a rear stage of a choke coil L2. The current flowing into a switch SW is controlled by the choke coil L2. Consequently, even if a recovery current is produced in a fly-wheel diode, the current flowing to the switch SW is limited, and it is not possible that the peak current flows to the switch SW.
