Abstract
A feedback architecture for ionizers that allows simultaneous adjustment of positive and negative ionizer power supplies. Balance and swing data are fed back to the ionizer through an intermediate module, which permits an extra level of signal processing. Swing information is returned to both power supplies in negative feedback mode. If swing is too high, both power supplies lower output. Balance is fed back in both negative and positive feedback mode. This architecture is compatible with multiple sensors and multiple ionizers.
