A power output circuit of a high voltage power supply

Abstract

The invention provides a power output circuit of a high voltage power supply, and relates to an electronic circuit. The power output circuit of the high voltage power supply is composed of a first power switch tube, a second power switch tube, a third power switch tube, a fourth power switch tube and a plurality of high-voltage transformer units, wherein each high-voltage transformer unit is composed of a primary coil and a secondary high-voltage coil; the primary coil is arranged at the inner layer and the secondary high-voltage coil is arranged at the outer layer; the primary coils of the plurality of high-voltage transformer units are connected in series in sequence to form a primary low-voltage loop, and the secondary high-voltage coils of the plurality of high-voltage transformer units perform superposed output in sequence; a source of the first power switch tube is connected to a drain of the second power switch tube, and then connected to head ends of the primary low-voltage loops of the plurality of high-voltage transformer units; and a source of the third power switch tube is connected to a drain of the fourth power switch tube and then connected to tail ends of the primary low-voltage loops of the plurality of high-voltage transformer units. The power output circuit of the high voltage power supply provided by the invention enables high voltages generated on each secondary high-voltage coil to be outputted in a superposition way, so as to meet the requirement of long distance arc ignition of a plasma device.

Description

Technical field [0001] The invention relates to an electronic circuit, in particular to a power output circuit. Background technique [0002] At present, plasma technology has been widely used. The way of using plasma to dispose of industrial hazardous materials, medical waste, and domestic waste is very different from the general incineration method. Plasma is a state formed under the ionosphere or discharge phenomenon. , The discharge effect causes the working gas molecules to lose their outer electrons and form an ion state. They collide with each other to generate high temperature. When the processed industrial hazardous materials, medical waste, and garbage are impacted by the high temperature and high pressure plasma, their molecules and atoms will Recombination produces new substances, thereby turning harmful substances into harmless substances. High-voltage ignition arc power supply is required in plasma equipment for the disposal of industrial hazardous materials, medic...
