Abstract

The paper analyzes and designs the main circuit of high-power IGBT inverted air plasma cutting power supply. It also discusses such key technologies as external characteristics of power drive circuit

inverter structure and medium frequency transformer

and presents corresponding design plan to improve efficiency

to reduce volume of whole machine

and to enhance power reliability. As a result

the power improves the whole performance and it can satisfy high-power requirement of 160 Amp. cutting current and t50 Volt cutting voltage. The resuk shows that this plan is reasonable and effective to satisfy cutting process requirements.
