The analysis of structures of multi-station sources for arc welding, designed on the base of capacitive energy storages, was carried out. Their prospects for creation of highly-efficient welding and technological systems are shown. The structures of centralized power supply systems of welding stations are considered, in which one powerful electric energy capacitor is used. A decentralized power supply system is more flexible, when the own electric energy capacitor is installed at each workplace. Its advantage consists in the fact that a standard rectifier of type VDGM can be used. For shipbuilding, a combined power supply system can be used, which implements the positive qualities of both power supply systems and provides a high quality and power efficiency of the welding process. As an example of the use of multi-station power sources, a scheme is given, which is based on the method of charge transfer. 13 Ref., 6 Fig.
