| Abstract: | The principle and main circuit structure of IGBT inverter for plasma sprayingare introduced. Por the high-power inverter (60kVA level) working in high voltage andlarge current,it's analyzed how to control and protect power switch device IGBT in adv-erse conditions. The safe work,decreasing power loss in switches and promoting efficiencyare assured by optimizing waveforms of work voltage and current. Two kinds of operationmodes are compared and optimized in order to realize reasonable operation of main circuitin large power. |
