BIPOLAR ION GENERATOR Russian patent published in 2006 - IPC F24F3/16 

FIELD: air conditioning.

SUBSTANCE: bipolar ion generator comprises corona and accelerating electrodes arranged in the air duct and connected to the secondary winding of the high-voltage transformer whose primary winding is connected with the capacitor and diagonal of the bridge voltage switch in series. The voltage switch is connected with the positive and common buses of the power source. The input of the switch is connected with the output of the unit for control of polarity of the high-voltage pulses whose first input is connected with the output of the unit for control of ion concentration and second input is connected with the output of the unit for control of ion polarity coefficient made of, e.g., pulse generator.

EFFECT: expanded functional capabilities.
