Description

technical field [0001] The invention relates to a novel high-frequency high-voltage power supply for electrostatic dust removal. Background technique [0002] With the continuous improvement of my country's industrialization scale, serious air pollution problems have been brought about. High-voltage electrostatic precipitators for industrial dust pollution control have attracted more and more attention because of their high dust removal efficiency, low energy consumption, and convenient maintenance and management. The high-voltage power supply is the core part of the electrostatic precipitator. Its power supply mode, operation mode and control mode have an important impact on the dust removal efficiency and operation stability of the electrostatic precipitator. At present, the high-voltage power supply used by the electrostatic precipitator basically adopts a single-phase thyristor power frequency phase-controlled power supply, and the disadvantage of this power supply is ob...
