Abstract
PURPOSE:To reduce input equivalent capacitance of a transistor, by making use of a rectifying device with a shorter recovery time in the reverse direction and a rectifying device with a greater reverse withstand voltage connected therewith in series. CONSTITUTION:A rectifying device 23 with a shorter recovery time in the reverse direction and a rectifying device 24 with a greater reverse withstand voltage are connected in series to a secondary winding 5 of a high voltage transformer 6. A current waveform (b) of only the rectifying device 23 is so formed that an inverse current flows corresponding to a recovery time, resulting in an increase in equivalent capacitance. On the other hand, a current waveform (c) of only the rectifying device is so formed that a period of an inverse current is shorter, resulting in a decrease in equivalent capacitance. And an input waveform (d) of both the rectifying devices 23, 24 is so formed that hardly an inverse current flows and the recovery time for the rectifying device 23 is made shorter. Even if the withstand voltage of the rectifying device 23 is over, most of the inverse voltage are applied to the rectifying device 24 with a decrease of resistance in the reverse direction on the part of the rectifying device 23, so that the rectifying device 23 is protected.
