An Optimization Harmonic Elimination Control Technique for Cascade Multilevel Inverter
In order to improve the quality of cascade multilevel inverter’s output voltage, this paper introduces an optimization harmonic elimination control technique. The harmonic of cascade multilevel inverter is controlled by the switch angels of inverter units. Through this technique, switch angels eliminate the low and middle frequency harmonic compositions and at the same time make total harmonic distortion rate of cascade multilevel inverter low are found. The correctness and accuracy of optimization harmonic elimination control technique are validated by simulation and experiment model.
