Research on Circuit Topology of High Voltage DC Pulse Power Supply for Removing Wide-Diameter Dust

摘要

A circuit topology of high voltage DC pulse dust removal power supply which can remove wide-diameter dust is proposed to solve the problem of the present high voltage dust removal power supply to fine particle dust removal effect is not great, and can't overcome the current situation of anti-corona problem under the condition of high resistivity power. The circuit topology adopts double voltage rectifier to realize DC high frequency base voltage, and pulse inversion to realize high voltage superimposed pulse. The circuit topology of the power supply can not only improve the dust removal effect of fine particle dust, but also suppress the phenomenon of anti-corona problem under the condition of high resistivity power. Meanwhile, the simulation model of the proposed circuit topology of the power supply is established, and the waveform control strategy is verified. Finally, the prototype of the power supply system is built to realize the topology of the proposed power supply circuit, and the dust removal effect of the proposed topology is verified by experiments.
