Abstract

The invention relates to a negative output fixed constant-current type electric breakdown high-voltage module power supply which comprises a power supply circuit packaged in a shell. A plurality of lead wires are welded on the power supply circuit, and the power supply circuit comprises a control circuit, a drive circuit, a voltage-stabilizing circuit, a high-voltage feedback circuit, a current feedback circuit and a combined high-voltage output circuit, wherein the voltage-stabilizing circuit is connected with the drive circuit through the control circuit, the drive circuit is respectively connected with the high-voltage feedback circuit, a current feedback circuit and the combined high-voltage output circuit, and the combined high-voltage output circuit is respectively connected with the high-voltage feedback circuit and the current feedback circuit. The invention has the advantages that ignition and maintenance of two high voltages are combined to output so that the use is convenient; output overvoltage protection is available; after a load is ignited, the output current is fixed and constant so that long-term stability is good; and the invention has small appearance size, light weight and easy installation of a PCB.

Description

technical field [0001] The invention relates to a negative output fixed steady-flow electric breakdown high-voltage module power supply for high-voltage ignition of fuel oil and gas, ignition of gas lasers, and other industrial applications, scientific research, medical treatment, and aviation equipment. Background technique [0002] With the development of science and technology and the expansion of market demand, users have higher and higher requirements for the quality, performance, and volume of power supply products. The existing industrial fuel, gas high-pressure ignition and gas lasers in scientific research, medical, aviation and other fields.
