Abstract

A hybrid arc welding system (10) includes a waveform generator comprising a switching type power converter (34). A welding torch (38) is operatively connected to the switching type power converter (34) to receive electrical energy and produce an electric arc (36) for welding. The system includes an engine-generator (30) and a rectifier (32) connected to receive an output of the engine-generator (30) and supply electrical energy to the switching type power converter (34). A battery (42) is connected to receive an output of the rectifier (32) and supply electrical energy to the switching type power converter (34). A bidirectional battery charge-discharge circuit (44) is connected between the rectifier (32) and the switching type power converter (34) and comprises a first and second electronic switches (58, 60). A controller (54, 66) is operatively connected to the bidirectional battery charge-discharge circuit (44) to control operations of the first and second electronic switches (58, 60) such that the bidirectional battery charge-discharge circuit (44) is configured to selectively conduct charging current from the rectifier (32) to the battery (42) and selectively conduct welding current from the battery (42) to the switching type power converter (34).
