Santamaria, G T

An electrostatic precipitator power supply circuit is described for generating voltage pulses on the precipitator while allowing a residual collection voltage to be retained on the precipitator during intervals between pulses, where the voltage of the pulses is substantially in excess of the residual voltage, the power supply circuit comprising: means for generating the high voltage pulses at the secondary inductance of a step-up transformer by discharging a capacitor through the primary inductance of the step-up transformer; the electrostatic precipitator connected to the secondary inductance of the step-up transformer to receive the high voltage pulses; and means for returning a portion of the high voltage pulses to the capacitor, and for maintaining the residual voltage on the precipitator during interpulse periods including means with a variable impedance adapted for providing a maximum impedance during interpulse periods and a minimum impedance during high voltage pulses and means for causing the variable impedance means to exhibit a minimum impedance during the return of a portion of the high voltage pulses.
