Abstract
|
Matrix converter as a universal power conversion device , with its unique topology and its many excellent features , it has tremendous value and broad application prospects . This paper introduces a matrix converter topology, the basic principles of modulation methods and commutation problems , and focus on Double Space Vector Modulation Strategy for Matrix Converter modulation process , the mathematical relationship between the amount of input and output is obtained . Then analyzed and summarized their advantages and disadvantages . Matlab simulation model of the system , detailing the various parts of the simulation module , switch conversion process optimization the Kudan modulation strategy , given its simplified carrier method , MATLAB / SIMULINK software simulation modulation strategy and its easy to achieve the correctness and feasibility of the method proposed based on improved proportional-integral ( PI ) control the MC closed-loop control method . This method will be the actual output voltage and the comparison of the desired output voltage deviation value as the amount of negative feedback , the use of improved tracking control on the output voltage given to the PI controller , enabling closed-loop control system . The matrix converter system hardware and software design in detail . The system controller functions mainly done by the DSP and FPGA , DSP modulation duty cycle to achieve real-time computing , FPGA responsible for the switch control signal decoding conversion work , and produced a matrix converter system prototype . Summarizes the research results and innovative work, and further research are proposed .
