Abstract: The disclosed technology describes methods and apparatus to convert and control power provided to a precipitator. An example embodiment of the disclosed technology includes a method for providing power to a device. The method includes receiving a first silicon controlled rectifier (SCR) signal and a second SCR signal from a controller device, generating a demand signal by the controller device based on a comparison of the first and second SCR signals, transmitting the demand signal to a power converter device, converting a first power signal from a first base frequency to a second power signal at a second base frequency, wherein the first base frequency is in the range of approximately 50 Hz to approximately 60 Hz and wherein the second base frequency is controlled in the range of approximately 100 Hz to approximately 1000 Hz, and switching the second power signal to the controller device.

Abstract: The present invention describes methods and apparatus to convert and control power provided to a precipitator. An exemplary embodiment of the present invention provides a precipitator power frequency converter system, which includes an insulated-gate bipolar transistor (“IGBT”) system and a converter control system comprising a microprocessor in communication with the IGBT system. In addition, the power frequency converter system provides a rectifier set in communication with the IGBT system. Furthermore, the input power received by the precipitator power frequency converter system is in a first frequency range of approximately 50 Hz to 60 Hz and the precipitator power frequency converter system can be enabled to provide an output power in a second frequency range between 400 Hz and 1000 Hz.
