Abstract
A method of balancing positive and negative ion output in an electrical ionizer having positive and negative ion emitters and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters includes automatically adjusting at least one of the positive and negative high voltage power supplies by ramping up or ramping down the at least one of the positive and negative power supplies at a predetermined rate. Another method of balancing positive and negative ion output in an electrical ionizer having positive and negative ion emitters and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters includes automatically adjusting at least one of the positive and negative high voltage power supplies by ramping up the at least one of the positive and negative power supplies at a predetermined rate upon initiation of the operation of the electrical ionizer.
