| Abstract: | In this paper, a novel method based on space vector pulse width modulation (SVPWM) for a five‐phase voltage source inverter is presented, which uses a proposed sampling time sharing (STS) technique to provide independent control of the fundamental component and the third harmonic. The main idea of the proposed method is that the entire sampling interval is distributed among them according to the amplitude ratio of the first‐ and third‐order components. Then, the space vector modulation process is performed separately for each harmonic in the allocated time interval. The most important features of this approach include the simplicity of the structure, flexibility in changing the ratio of harmonics, and a significant reduction in computational complexity. Unlike many existing methods that require heavy control algorithms or complex modeling, the proposed STS‐SVPWM technique offers a simple yet efficient method. To evaluate the performance, detailed simulations were conducted in the MATLAB/SIMULINK environment, where the results indicate the high ability of the proposed method to generate independent and stable harmonics. Next, for practical validation, this method was implemented and tested on a laboratory platform based on a TMS320F28335 DSP controller. The laboratory results are in good agreement with the simulation results and confirm the efficiency and accuracy of the proposed method. In summary, the introduced method can be considered as an effective and innovative solution in the design of five‐phase inverters requiring independent harmonic control. [ABSTRACT FROM AUTHOR] |
