December 2012: Redkoh is Awarded ESP Controls PatentSYSTEMS AND METHODS OF POWER CONVERSION FOR ELECTROSTATIC PRECIPITATORS Serial No.: 13/714,673
To be truly effective, an electrostatic precipitator must be energized to hold a precise and consistent amount of electrical charge. Thus, electrostatic precipitators require precise and efficient power supplies to apply the proper potential to the precipitator. Conventional power supplies for electrostatic precipitators are often inefficient. Furthermore, many systems that may enable the supply of power at a relatively high frequency range are costly to implement and are incompatible with existing electrostatic precipitator systems.
It is important to have a device that is compatible with existing hardware.
Redkoh’s technology includes methods and apparatus to convert and control power provided to the electrostatic precipitator.
The Redkoh control is able to receive an (SCR) signal from a control device, and generate a demand signal, converting a first power signal from a first base frequency to a second power signal at a second base frequency.
The precipitator power frequency converter system includes an insulated-gate bipolar transistor (“IGBT”) system, a converter control system that includes a microprocessor in communication with the IGBT system, and is then able to drive either a conventional TR or a specifically designed High Frequency TR at a frequency of choice.
During the testing phase and subsequent period, all customers using the technology have gone on to upgrade their systems using solutions provided by Redkoh.
