Minimum Harmonic Voltage Modulation Method of Near Four Vector for Five-phase Voltage Source Inverter
摘要
Abstract
To improve the output voltage of five-phase voltage source inverter (VSI) and reduce its harmonic of the phase voltage,a space vector pulse width modulation (SVPWM) algorithm of five-phase VSI with the Minimum harmonic based on near four voltage vectors was proposed.By introducing the method of the synthetic vector,the three harmonic sub plane is analyzed,and the modulation algorithm of the minimum harmonic voltage is achieved.In the sine modulation region of adjacent four vector,the adaptable selection of suitable synthetic vector,can suppress the phase voltage harmonic to zero;In non-sinusoidal modulation region,the two basic synthetic vector is obtained inthe sector by the optimal solution of harmonic voltage in harmonic sub plane.By comparing with the an improved four vector modulation algorithm.the harmonic component of minimum harmonic algorithm is minimized.Simulation and experimental results verify the correctness and feasibility of the proposed algorithm.关键词
