High-voltage pulse power circuit with magnetic energy optimization

Abstract

The invention discloses a high-voltage pulse power circuit with magnetic energy optimization, comprising first to second coupled inductors, first to second resonant inductors, a coupled capacitor, a resonant capacitor, a damping resistor, a GTO (gate turn-off thyristor) two-way switch, a thyristor switch, an antiparallel diode, a dust remover, a first direct-current power source and a second direct-current power source; the first direct-current power source and the second direct-current power source are coupled through the first to second coupled inductors, and output is loaded to two ends of the coupled capacitor. High-voltage pulse dust removal is achieved by generating pulse high-voltage waveform through single resonance by using pulse high-voltage power topology; through secondary resonance, pulse high-voltage waveform is generated by single resonance to reduce the problems of voltage trailing, direct-current voltage superposition, pulse oscillation and the like; the high-voltage pulse power circuit is suitable for electrostatic precipitation and power supply, direct-current voltage, pulse amplitude, pulse frequency and pulse repetition frequency are all controllable, power source stability is improved, and dust removal efficiency is greatly improved.

Description

technical field [0001] The invention relates to a high-voltage power supply circuit, in particular to a high-voltage pulse power supply circuit with magnetic energy optimization, and belongs to the technical field of environmental protection equipment. Background technique [0002] The rapid development of the country has resulted in increasing environmental pollution. After entering the 21st century, the country has paid more and more attention to the control of air pollution, and accordingly issued various air emission standards. Traditional electrostatic precipitators can no longer meet the existing emission standards, and the innovation of electrostatic precipitators has become inevitable. Among them, the high-voltage power supply is the key to affect the working effect of the electrostatic precipitator. Because the traditional industrial frequency power supply and high frequency power supply are both constant current power supplies, high specific resistance and fine p...

AI Technical Summary

Problems solved by technology

[0003] Therefore, several pulse power supplies have been proposed at home and abroad, such as the general electric wide pulse designed by GEESI, but these pulse power supplies cannot independently adjust the pulse voltage, pulse width, and pulse repetition frequency for a single time. Controlled defects that affect the dust removal effect of the electrostatic precipitator

The fourth-generation pulse power supply proposed by Smith Company of Denmark can adjust the pulse waveform, but there are problems that the pulse waveform cannot be optimized, resulting in voltage tailing, DC voltage superposition, and pulse oscillation, which will seriously affect the dust removal effect and operation stability of the pulse power supply.
