Abstract :
Combining switching characteristics of power electronic devices and state transitions in carrier phase-shifted SPWM (CPS-SPWM), this paper uses graphic Stateflow toolbox of Matlab/Simulink to design the process of CPS-SPWM. Then it is applied to STATCOM which is integrated with distribution transformer (DT-STATCOM) for PWM signal generation. Simulation results are presented to prove that the method is valid and effective for reactive power compensation. Meanwhile, software-in-loop (SIL) test and automatic code generation are also carried out. Results of experimental test with DSP TMSF28335 have validated the theoretical contributions of the paper. PWM signal comparison of both simulation and experiment result shows that this method has both the feasibility and effectiveness of software and hardware design. With this method, design of CPS-SPWM can be more rapid, efficient and convenient.
