Multi-frequency static neutralization |
摘要 |
Static neutralization of a charged object is provided by applying an alternating voltage having a complex waveform, hereinafter referred to as a "multi-frequency voltage", to an ionizing electrode in an ionizing cell. When the multi-frequency voltage, measured between the ionizing electrode and a reference electrode available from the ionizing cell, equals or exceeds the corona onset voltage threshold of the ionizing cell, the multi-frequency voltage generates a mix of positively and negatively charged ions, sometimes collectively referred to as a "bipolar ion cloud". The bipolar ion cloud oscillates between the ionizing electrode and the reference electrode. The multi-frequency voltage also redistributes these ions into separate regions according to their negative or positive ion potential when the multi-frequency voltage creates a polarizing electrical field of sufficient strength. The redistribution of these ions increases the effective range in which available ions may be displaced or directed towards a charged object.
