PURPOSE:To shorten the rise time of a power output level by providing a means particularly suppling currents only on the rise time of the base currents of a switching transistor. CONSTITUTION:A rectangular wave signal is inputted to a remote control circuit 26 from an input terminal 25, and a switching transistor 6 connected in series with a primary winding 3 for a transformer 2 for boosting is ON-OFF controlled by the input of the signal. High voltage induced in a secondary winding 5 for the transformer 2 for boosting is lead out of output terminals 8, 9 through a capacitor 7 for resonance. A base current supply means 27 particularly supplies a base for the switching transistor 6 with currents only on the rise time of the base currents of the switching transistor 6. |
