Abstract

In one embodiment of the invention, a method of automatically balancing ionized air stream created in bipolar corona discharge is provided. The method comprises: providing an air moving device with at least one ion emitter and reference electrode connected to a micro-pulsed AC power source, and a control system with at least one ion balance monitor and corona discharge adjustment control; generating variable polarity groups of short duration ionizing micro-pulses: wherein said micro-pulses are predominantly asymmetric in amplitude and duration of both polarity voltages and have a magnitude of at least one polarity ionizing pulses exceed the corona threshold.
