Abstract
Power sources for welding applications and the like are provided in accordance with the teachings of the present invention. An inverter arrangement comprising a plurality of inverters, having inputs connected in series, receive portions of a d.c. load from a plurality of series connected smoothing capacitors. The smoothing capacitors are connected to form a voltage divider and apply the resulting portions of the d.c. load to the plurality of inverters. This enables the plurality of inverters to be dimensioned in a manner so as to withstand the smaller portions of the d.c. load resulting from the voltage division.
