Carrier Based SVPWM Method for Multi-Level System Considering Harmonic Distortion Factor
2001
In most inverter/converter applications SVPWM method is a preferred approach since it shows good characteristics in linear modulation range and waveform quality In this paper, we propose a new carrier based SVPWM method for multi-level system. First, we survey the conventional carrier based SVPWM method, and investigate the problem of the conventional one for the multi-level system with the focus on the switching frequency harmonic flux trajectories Finally, we propose a new carrier based SVPWM method that can reduce harmonic distortion Simulation and experimental results are given for verification of the proposed SVPWM method.
