Abstract: A polarity control unit includes a flag storage unit that stores any one of a first polarity pattern by which a positive direct-current voltage is applied to discharge needles in a first group and a negative direct-current voltage is applied to discharge needles in a second group and a second polarity pattern by which a negative direct-current voltage is applied to the discharge needles in the first group and a positive direct-current voltage is applied to the discharge needles in the second group, a flag update unit that rewrites one flag stored in the flag storage unit to another flag when a power switch is turned on from its off state or is turned off from its on state, and a command unit that commands a polarity pattern corresponding to the flag stored in the flag storage unit to be output from the polarity output unit.

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.

Abstract: An ionizer includes: a positive-side transformer, and a negative-side transformer; a positive-side high-voltage output circuit that has a first input terminal and a second input terminal that are respectively connected to a ground terminal and a power supply terminal, the ground terminal and power supply terminal being provided on the secondary of the positive-side transformer, and also has a first output terminal from which a direct-current positive high voltage is output; a negative-side high-voltage output circuit that has a third input terminal and a fourth input terminal that are respectively connected to a ground terminal and a power supply terminal, the ground terminal and power supply terminal being provided on the secondary of the negative-side transformer, and also has a second output terminal from which a direct-current negative high voltage is output; and a discharge electrode connected to the first output terminal. The ground terminal in the positive-side transformer and the first input terminal in the positive-side high-voltage output circuit are mutually connected through an attenuating capacitor.

Abstract: An ionizer includes a polarity output unit that can selectively output, to a discharge unit, one of a first polarity pattern where the polarity output unit applies a positive direct-current voltage to a first group of discharge needles and applies a negative direct-current voltage to a second group of discharge needles and a second polarity pattern where the polarity output unit applies a negative direct-current voltage to the first group of discharge needles and applies a positive direct-current voltage to the second group of discharge needles and a polarity control unit configured to control the first and second polarity patterns. The polarity control unit includes a current detection unit configured to detect respective direct currents passing through the first group of discharge needles and the second group of discharge needles. When the difference between the current values of the first group of discharge needles and the second group of discharge needles detected by the current detection unit becomes greater than a predetermined value, the polarity control unit switches between the first and second polarity patterns.
