technical field [0001] The invention relates to a power supply for an electric precipitator, in particular to a high-energy pulse power supply system with a stable amplitude for the electric precipitator. Background technique [0002] The electrostatic precipitator is a dust removal device that charges the dust particles and deposits them on the electrodes under the action of a high-voltage electric field force, thereby separating the dust particles from the dust-containing gas. The power supply of traditional electrostatic precipitator is high-voltage DC power supply. The high-voltage DC provided is pulsating and has ripples. There are phenomena such as low breakdown voltage, poor charging effect of fine dust and high specific resistance dust, and back corona. Affect the dust removal effect.

Problems solved by technology

However, because the high-voltage DC voltage output by the existing DC high-voltage fundamental wave power supply still has ripples, resulting in unstable pulse voltage superposition, resulting in frequent discharge of the electrostatic precipitator and frequent power outages, the superimposed pulse voltage cannot be used. The dust collection effect is worse; at the same time, the peak value of the pulse voltage generated by the pulse generating circuit fluctuates, and it is easy to cause internal breakdown of the electrostatic precipitator.
