MICROPULSE BIPOLAR CORONA IONIZER AND METHOD

摘要

A solution for static charge neutralization that includes providing at least one pulse train pair (18) to an emitter (12) of an ionizer (10) is disclosed. The pulse train pair (18) is disposed to include a positive pulse train (30) and a negative pulse (32) train that alternate in sequence. The positive pulse train (30) includes an ionizing positive voltage waveform (64), while the negative pulse train (32) includes an ionizing negative voltage (84) waveform. These ionizing positive and negative voltage waveforms (64, 84) alternately create voltage gradients across the emitter (12) and a reference electrode (14) of the ionizer (10), generating by corona discharge an ion cloud (40) that includes positive (34) and negative ions (36).
