Abstract
A bipolar ionization apparatus includes a positive high voltage power supply having an output with at least one positive ion emitting electrode connected thereto and configured to generate positive ions. A negative high voltage power supply has an output with at least one negative ion emitting electrode connected thereto and is configured to generate negative ions. A controller for an ionizer outputs a positive high voltage ionization waveform and a negative high voltage ionization waveform. The controller simultaneously adjusts an amplitude and a duty cycle of each of the waveforms.
