PROBLEM TO BE SOLVED: To provide a high-voltage generator which prevents ripples in the quantity of collected dust caused by the ripple of power voltage, increase in the quantity of generated ozone, and deterioration due to drop in collecting capacity by the dirt of an electrode over a long use. SOLUTION: This high-voltage generator has a DC power source, which is connected to the primary side of a transformer for generation of high voltage and whose other end is connected to a second switching element, a control circuit which controls digital signals with a terminal for generation of high voltage provided on the secondary side of that transformer for generation of high voltage, and current detectors which are provided at the first switching element and the second switching element for amplifying those signals, and here the signals are fed back to the control circuit. |
