Abstract: The principle of inverters parallel operation has been analyzed. It proposed a control scheme for inverter modules in parallel operation based on CAN Bus in the DSP chip (TI TMS320LF2407A), using the CAN for communication among electronic control units. The system has many good features, which make it a very promising candidate in terms of
configuration flexibility, redundancy, robustness. The method of realizing this system based on CAN Bus in hardware and software will be described in detail in this paper.
