FIELD: electrical engineering; welding.
SUBSTANCE: invention relates to the field of energy conversion with one current input parameters into current energy with other output parameters, in particular to a power source for welding. The effect is achieved due to the fact that a modular source has been developed, containing a housing that contains a power unit and a control unit. The modular source is characterized by the fact that the power unit consists of several current source modules connected to the input in parallel. The control unit is configured to independently control each current source module.
EFFECT: improved reliability of the current source and stability of output current.
