Abstract

The invention discloses a photo-electrically isolated voltage buffer power supply. The photo-electrically isolated voltage buffer power supply is characterized by mainly comprising a control chip U2,a transformer T1, a transformer T2, a diode rectifier U1, an amplifier P, a triode VT1, a triode VT2, a triode VT3, a capacitor C3 and the like, wherein the positive electrode of the capacitor C3 is connected with the negative electrode output end of the diode rectifier U1 while the negative electrode of the capacitor C3 is connected with the positive electrode output end of the diode rectifier U1. The photo-electrically isolated voltage buffer power supply has relatively high bandwidth, so that the dynamic response speed of the power supply can be improved, thereby enabling an electrostatic dust collector to be higher in starting speed.

Description

technical field [0001] The invention relates to a power supply, in particular to a photoelectrically isolated voltage buffer power supply. Background technique [0002] Due to its high dust removal efficiency and low operating cost, electrostatic precipitator plays a very important role in reducing harmful dust discharged into the atmosphere. It is currently a widely used environmental protection equipment. It has been widely used in in people's lives. However, the power supply used by the existing electrostatic precipitator is easily damaged by impact, and in serious cases, the electrostatic precipitator will be damaged. Contents of the invention [0003] The purpose of the present invention is to solve the defect that the power supply used in the current electrostatic precipitator is easily damaged by impact, and to provide a voltage buffer power supply that can be photoelectrically isolated. [0004] The purpose of the present invention is achieved through the followi...
