BIPOLAR ION GENERATOR Russian patent published in 2010 - IPC F24F3/16 

FIELD: physics.

SUBSTANCE: generator is designed for saturating air with ions of both charges. The generator has a low-frequency pulse generator, an ion concentration control unit, a pulse distributor, three voltage switches, two identical groups of corona and acceleration electrodes fitted in the blown housing, which are connected to output windings, and first and second high-voltage transformers. Primary windings of the said transformers are connected by one lead to outputs of the first and second switches respectively, and second leads of the primary windings are combined and connected to the output of the third switch. The generator has two XOR elements, whose outputs are connected to inputs of the first and second switches respectively. The first inputs of the logical elements are connected to outputs of a pulse distributor. Second inputs of the XOR elements are combined and connected together with the input of the third voltage switch to one or different outputs of a low-frequency pulse generator depending on the type of output elements of the pulse distributor. Al three voltage switches used are in form of complementary emitter followers on Darlington transistors and primary windings of the transformers are connected to outputs of the switches in antiphase.

EFFECT: simplification of the electrical circuit of the ion generator.
