A DSP based real-time simulation of Dual-Bridge Matrix Converters

This paper investigates the state-space modeling and real-time simulation of dual-bridge matrix converters (DBMC) based on a DS1104 digital signal processor. This single board controller of dSPACE uses the matlab-simulink software as a front-end for the implementation of graphic models in block- diagram format. First, the state-space model of the converter and the SVM control system are designed with simulink in the form of user-friendly block-diagram. Next, C-codes are generated from the block diagrams with the real-time workshop. After that the executable code is automatically downloaded to the target DSP board. Finally, real-time simulation results are presented and compared to those obtained using off-line computer simulations. Good agreement is observed between both simulation results which shows the effectiveness and accuracy of the proposed realtime simulator.
