This paper introduces the working principle of high voltage source with half-bridge inverter for electronic beam welder. Based on the characteristic of power source and PLC controlling technology, IGBT is used as inverter to realize a small volume of the power source and soft-start of the power source. A/D and D/A technology is used in auto-adjusting circuits to improve the reliability of power source. There are protection circuits in the power source . The experiments show this power source meets the requirements of welding technology.
