Abstract
A high voltage generation circuit is equipped with an AC power source, a positive polarity high voltage generating circuit, and a negative polarity high voltage generating circuit. A phase converter that converts the phase of an AC voltage supplied from the AC power source is disposed between the AC power source and the positive polarity high voltage generating circuit, or between the AC power source and the negative polarity high voltage generating circuit.
Claims6
A high voltage generation circuit for alternately applying a positive pulse high voltage and a negative pulse high voltage to a load, comprising:
- an AC power source;
- a positive polarity high voltage generating circuit;
- a negative polarity high voltage generating circuit which is different from the positive polarity high voltage generating circuit;
- and
- a circuit output which outputs to the load a combined voltage which includes an output of the positive polarity high voltage generating circuit and an output of the negative polarity high voltage generating driving circuit,
- wherein a phase converter configured to convert a phase of an AC voltage supplied from the AC power source is disposed between the AC power source and the positive polarity high voltage generating circuit, or between the AC power source and the negative polarity high voltage generating circuit.
