The present invention relates to an ionizer capable of enhancing generation efficiency of positive-side high-voltage due to a positive-side high-voltage output circuit, as well as reducing ripple voltage generated in a negative-side high-power output circuit in order to prevent negative high-voltage output from being reduced. The ionizer according to the present invention comprises: a positive-side transformer (8) and a neagive-side transformer (9), of which primary sides are alternately connected to alternating current power sources (5,6); a positive-side high-voltage output circuit (10) of which a first input terminal (13) and a second input terminal (14) are connected to a secondary-side ground terminal (8a) and a secondary-side power terminal (8b) of the positive-side transformer (8), and which outputs direct-current positive high-voltage from a first output terminal (15); a negative-side high-voltage output circuit (11) of which a third input terminal (20) and a fourth input terminal (21) are connected to a secondary-side ground terminal (9a) and a secondary-side power terminal (9b) of the negative-side transformer (9), and which outputs direct-current negative high-voltage from a second output terminal (22); and a discharge electrode (3) connected to the first output terminal (15). The secondary-side ground terminal (8a) of the positive-side transformer (8) and the first input terminal (13) of the positive-side high-voltage output circuit (10) are connected via a condenser (16). |
