ABSTRACT:
There is provided a precipitator system including a voltage controller which produces from an alternating power source a variable output. This variable output drives a high voltage converter which applies a high voltage to a precipitator. This variable output is controlled by a control signal from a command subsystem. Preferably, the command subsystem is operative to repress the drive to the high voltage converter in response to its loading exceeding a predetermined limit during a corresponding limit interval. After this limit interval, the command subsystem is operative to rapidly restore productive drive to the high voltage converter, preferably by the next half cycle of the power source that has a polarity opposite to that existing at the beginning of the limit interval. In this fashion stablized operation is quickly achieved. Also included, preferably, is a conductive element that is coupled to the high voltage converter. This conductive element conducts in response to variations in the extent to which the high voltage converter is being driven. The command system may store successive values of the voltage across the conductive element, using such values to adjust the control signal according to a predetermined relationship. Such an arrangement can be used to adjust the control signal when a spark is imminent, thereby avoiding it.
