Abstract

A controller can control controlling a precipitator. The controller has a power modulator. The modulator has a control terminal and is coupled to the precipitator. The power modulator is adapted to be powered by an alternating current. The modulator can operate to regulate the drive to the precipitator in response to a control signal on the control terminal. The controller also has a measurement means coupled to the precipitator for providing a plurality of measurement signals corresponding to a plurality of operating parameters of the precipitator. Also included is a processing means having a program. The processing means is coupled to the measurement means and the power modulator for producing the control signal and for regulating the power modulator in response to the measurement signals. The processing means includes a spark concurrence means responsive to at least one of the measurement signals for spark synchronously storing a sparktime signal having a magnitude corresponding to a given one of the operating parameters. The sparktime signal is distinctly stored and designated as a signal occurring during a spark. The processing means can vary the control signal in response to the sparktime signal.
