PURPOSE:To obtain an output of waveform produced by superposing an AC on a DC in a compact configuration in a power source for intermittently controlling the primary side of a step-up transformer to produce a high voltage output at the secondary side by controlling the intensity of the high voltage output in accordance with the prescribed frequency. CONSTITUTION:In a power source for supplying a high voltage output to a load 18 connected with the secondary side by connecting a switching element 28 with the primary side of a step-up transformer 14 to intermittently flowing the primary side current, the secondary side high voltage output is controlled in accordance with the prescribed frequency. To this end, a high voltage current detector 29 is, for example, provided in the secondary side circuit to compare the detected output by an error amplifier 25 with a reference voltage generated from a reference voltage generator 30. The DC deviation value 31 in input to an AC oscillator 26 having the prescribed frequency to obtain a signal 32 produced by superposing an AC on a DC, Thereby controlling the controller 27 of the element 28. |
