Embodiment Construction
[0007] Below in conjunction with accompanying drawing, the numerical control plasma power source of multiple plasma cutting torches of the present invention is described in further detail:
[0008] Using DSP as the control chip of the power supply makes the inverter power completely digital. As can be seen from the accompanying drawings, the present invention includes a total DSP digital signal controller, said total DSP digital signal controller is connected with a plurality of sub-DSP signal controller input terminals through control lines, and each sub-DSP signal controller is connected by at least two Each inverter module is connected with a plasma cutting torch, and each inverter module is connected with CAN bus (controller area network). Each inverter module collects the voltage and current at the output end of its own inverter bridge, and actively transmits its own voltage, current and power to other inverter modules through the CAN bus. Since the transmission speed of ...
