In order to remedy the defect of frequency conversion technology, a new idea of pulse blocking AC frequency conversion based on dSPACE was proposed. The RTW was used to generate code for the mathematical model of the constructed blocking AC frequency conversion system, which was used to implement the dSPACE-based chopping voltage control strategy. The ControlDesk software platform was used to change the parameters and variables in the experiment, and the purpose of frequency conversion voltage regulation was finally realized. The frequency conversion system was simulated in the MATLAB 2011a environment. The simulation results were consistent with the experimental results and the theory, which verifid the correctness and feasibility of the control strategy of the system, and also provided the basis for the design and application of the industrial field variable frequency speed control system.

Key words: AC frequency conversion, dSPACE, ControlDesk, pulse blocking type, PWM control, voltage regulation and frequency modulation, MATLAB
