By ase of the CAN bus, the synergic control between the master and slave power supplies can be realized. And in this way, their peak currents can be guaranteed to be alternative and the interference between the two arcs can be decreased efficiently. The hardware design, software design and relative tests are provided in this paper. Tests show that the power supply can meet the design requirements of twin-wire welding.展开更多
