Abstract: In allusion to the deficiency of large electric field voltage fluctuation and uncontrollable cremation performance, the traditional power supply of industrial frequency was reformed and promoted to the high frequency power supply, to make each key index of electrostatic precipitator increased greatly. This paper gave the design principle of high frequency power supply and analyzed the high frequency power supply. The practical application of coal fired power plant shows the good results.
Key words: high frequency power; electrostatic precipitator; energy conservation; precipitate efficiency
