A high voltage pulsed power system for electrostatic precipitators

With the increasing demands for a clean environment, development of air cleaning systems has been receiving increased attention. One of the key technologies in the electrostatic precipitator (EP) is a high voltage pulsed power supply, which affects the performance of the overall system. In this study, a high voltage microsecond pulse power supply for an EP is developed for 500 MW coal power plant emission controls. The power supply has a DC and a pulsed source. The ratings of the DC and the pulsed source are 60 kV/800 mA and 70 kV/400 mA, respectively.
