High-voltage pulse output circuit, method and exhaust gas removal device

Abstract

The invention provides a high-voltage pulse output circuit and method and a tail gas removing device, and relates to the technical field of electronic circuits. The high-voltage pulse output circuit comprises a first switch unit, a second switch unit, a first energy storage unit and a boost unit; the first switch unit includes a thyristor; the second switch unit comprises a first switch device anda second switch device, the high-potential end of the first switch device and the low-potential end of the second switch device are connected and then connected to the low-potential end of the firstswitch unit; one end of the first energy storage unit is connected with the cathode of a DC power supply, and the other end of the first energy storage unit is connected with the low-potential end ofthe first switch device and the high-potential end of the second switch device; and the boost unit comprise a primary winding and a secondary winding, the two ends of the primary winding are connectedwith the low-potential end of the first switch unit and the cathode of the DC power supply respectively, and the two ends of the secondary winding is grounded and used to output a high voltage pulserespectively. Thus, the problem that the switch unit tends to be damaged in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a high-voltage pulse output circuit, a method, and exhaust gas removal equipment. Background technique [0002] Production equipment, automobiles and other devices generally generate and discharge polluting gases during use.
