A Voltage-Doubler/Marx-Generator-Based Multi-Module High-Voltage Pulse Generator with High- Frequency Charger for Electrostatic Precipitators

Due to the urgent demands for a clean environment, many up-to-date researches have focused on developing air cleaning systems. Recently, many studies have assured that the pulse energization-based electrostatic precipitator (ESP) is a good candidate for enhancing the removal efficiency of high-resistivity fractional particles, resulted from commercial and industrial applications. Consequently, this paper proposes a multi-module pulse power supply, in series-stacked version, fed from isolated high- frequency square-wave AC sources via utilizing multiple of ring transformers. Each module comprises of the voltage-doubler (VD)/marx-generator (MG) stages. In the presented approach, the two various output pulse types, namely, rectangular pulse and multilevel one, are proposed. The suggested approach is featured with its modular construction and its scalability for generating any desired voltages' values for pulse energization with a controllable repetition rate and an adjustable pulse width. The operational principles, along with design equations, have been illustrated for the presented scheme. A numerical comparison is carried out to show the merits of the suggested pulse generator compared to the other approaches in the literature. The findings of simulated case-study are used to validate the presented pulse generator.
