Pulse power supply for electrostatic precipitator based on intermediate frequency charging

The invention discloses a pulse power supply for an electrostatic precipitator based on intermediate frequency charging. The power supply comprises a three-phase power frequency rectification filtering unit, a single-phase intermediate frequency inversion unit, an intermediate frequency step-up rectifying unit, a pulse generating unit and a pulse basic power superimposing unit; the three-phase power frequency rectification filtering unit is used for rectifying and filtering a three-phase power frequency AC low voltage and obtaining a DC voltage; the single-phase intermediate frequency conversion unit is used for converting the DC voltage into an intermediate AC voltage with a fundamental wave being 400 Hz; the intermediate frequency step-up rectifying unit is used for rectifying the intermediate frequency AC voltage into the DC voltage of 2.3 kV; the pulse generating unit is used for forming the DC voltage into a high voltage pulse; and the high voltage pulse enters the electrostatic precipitator and is super
