【 摘 要 】

Different proton irradiation regimes were tested to provide more than 20 kHz-frequency, soft reverse recovery "snap-less" behavior, low forward voltage drop and leakage current for 50 mm diameter 7 kA/400 V welding diode Al/Si/Mo structure. Silicon diode with such parameters is very suitable for high frequency resistance welding machines of new generation for robotic welding.
