STUDY ON IGBT INVERTER FOR PLASMA SPRAYING

Abstract

Abstract: The principle and main circuit structure of IGBT inverter for plasma spraying are introduced. For the high-power inverter (60kYA level) working in high voltage large current, it's analyzed how to control and protect power switch device IGBT in adverse conditions. The safe work, decreasing power loss in switches and promoting efficiency are assured by optimizing waveforms of work voltage and current. Two kinds of operation modes are compared and optimized in order to realize reasonable operation of main circuit in large power.

Key words: IGBT, Inverter, Plasma spraying
