Abstract:

In order to improve the reliability and on-site operation performance of the homemade multi-function welding inverter in severe construction environment of nuclear power plant, the high-frequency soft-switching technology and the ARM-based prior embedded control system are adopted to realize the digital control of the inverter and the soft energy transfer of power services, and further to improve the reliability and dynamic response capability of the system. It is found that the optimization design of output characteristics of the power supply helps to implement the DC/pulse output of the inverter and increase the success rate of arc ignition. Thus, both the arc ignition and the welding quality are improved and the demands of the nuclear power plant construction are successfully fulfilled.

Key words: nuclear power plant construction, multi-function welding inverter, soft switching, digital control, embedded system
