| Abstract: | The topologies of cells cascaded multilevel inverter and work principle of carrier phase shift control were simply introduced.Through MATLAB simulation experiment,first,we can get the changes of output voltage while the cascaded number,carrier shifted angle and modulation index change.Then carrier phase shifting high voltage system driving load was analyzed by simulation.The results of simulation showed that the invertor has almost sine wave of output voltage.And the simulation result was consistent with theoretical analysis. |
