Abstract

An electrically variable current limiting reactor (24) which is usable in association with a power supply (14-22) for an elec-trostatic precipitator (10, 58) is disclosed herein. The current limiting reactor (24) is capable of having the inductance value there-of varied responsive to system operation conditions. Most particularly the inductance of the current limiting reactor (24) can be modified responsive to the form factor of the sinusoidal AC input current to the power supply transformer. Additionally, the in-ductance of the current limiting reactor (24) can be controlled responsive to the fractional conduction of the full wave rectified current waveform at the output of the full wave rectifier of the power supply. Other conditions can be monitored to control the inductance value of the current limiting reactor (24) such as physical system parameters. An automatic operating control may modify the inductance of the current limiting reactor responsive to the current entering the primary of the transformer of the pow-er supply.
