Abstract

PURPOSE:To prevent the delay of cutoff of a switching transistor to stabilize the oscillating operation, by interposing a diode in the discharging loop of a capacitor, which is formed through the switching transistor, in the direction where discharging is stopped. CONSTITUTION:When the charge of a capacitor 5 is discharged to a power source 1 in a pause time, the base current to be supplied to a transistor TR3 is given to the TR3 through a diode 7 forward as it is. In the course from the turn-on state to the cutoff state of the TR3, even if the current flowed to a secondary winding 2b is inverted, the capacitor 5 is not short-circuited through the TR3 because this current is stopped by the diode 7. Consequently, even if the operating frequency is high and the rise time and the fall time of the TR3 become a problem, the operation is stabilized.
