Micropulse bipolar corona ionizer and method

摘要

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