The Control System of High Voltage Electrostatic Precipitator Based on FPGA

It is urgent to study a new control system for improving the efficiency of electrostatic precipitator. The System-on-a-Programmable-Chip (SOPC) development board, which belongs to the series of Cyclone of Altera Company, is used as the development platform. Analog Digital (AD) conversion module, voltage control module and overall control module of the electrostatic precipitator are designed and the simulation waveform of the system is analyzed, based on the programmable logic device EP1C12Q240C6 and Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) programming language. The results show that: by using Field Programmable Gate Array (FPGA) as the control, transformation of AD is accurate and fast and high voltage power supply is stable, which leads to a certain value for generalization.
