Abstract: The common C MEX function is confined to calculate child module, it is not used to design the overall control scheme. The coder is not compatible with the DSP chip software, and can’t be done transplantation and experiments. This paper proposes a new multiple file structure C MEX function. The main function, child module and header file are integrated to the multiple file structure. The child module is called by the main function to calculate the whole simulation program. The C MEX code is designed based on the modular multilevel topology rectifier current vector control algorithm. It uses fixed-point DSP model, which can realize efficient transplantation. The simulation results show that the C MEX function realizes the current decoupling and has the characteristics of high integration and efficiency.

Key words: multilevel topology, multiple file structure, vector control, fixed-point
