Abstract: A new pulse power used for the low temperature plasma surface hardening of austenitic stainless steel was developed. The advanced TC787 trigger module was used to control the three-phase full-controlled bridge rectifier. So the trigger circuit is simple, reliable and easy to debug. The IGBT bridge inverter with the soft switching technology reduced the switching losses. The arc discharge detection circuit and the over-current protection circuit can avoid the power damage caused by the over-current, and increase the power stability.
Key words: austenitic stainless steel; low temperature plasma surface hardening; pulse power
