Abstract

A high-voltage power supply for the electrostatic oil soot exhauster is composed of input rectifier, power amplifier, high-voltage transform circuit, high-voltage output rectifier, amplitude modulator, and frequency modulator.

Description

technical field [0001] The invention relates to a high-voltage power supply for electrostatic dust removal equipment, in particular to a high-voltage power supply for electrostatic oil fume purifiers. Background technique [0002] The existing high-voltage power supply for electrostatic oil fume purifiers mainly has two circuit structures. One is a power frequency power supply. The volume is large, the output waveform is not good, and the interference to the power grid is large; the second is a high-frequency switching power supply. Although its volume is small, it uses pulse width or frequency conversion modulation, which increases the cost. [0003] The above two kinds of power supplies are common to electrostatic range hoods. Since the electric field generator has the following three basic requirements for high-voltage power supplies: 1. Pulse output, 2. Stable and reliable output, 3. Adjustable amplitude, 4. Impedance matching . The above two power sources cannot fully...
