Plasma for inverter

Abstract

The invention relates to a plasma for an inverter. The plasma comprises an input system, a switch power supply, a three-phase rectifying circuit, a filtering circuit, an inverting circuit, a transformer, a medium frequency rectifier, a reactor wave filter and an output system, wherein the input system is communicated with the switch power supply, the switch power supply is connected with the three-phase rectifying circuit, the three-phase rectifying circuit transmits the current to the inverting circuit through the filtering circuit, the output voltage of the inverting circuit is transmitted to the transformer, and the transformer outputs voltage and outputs direct current from the output system through the medium frequency rectifier and the reactor wave filter in sequence. The plasma for inverter disclosed by the invention utilizes the mature semi-bridge inverting circuit, so that the failure rate of the whole machine is low and the maintenance cost is low; the advanced electronic circuit is used for providing quick power supply regulation and control, so that the cutting operation property is good and the conversion efficiency is high; and a direct current inverting square wave and a DW rectifying bridge are utilized to improve the reliability of the machine.
