Carrier based SVPWM method for multi-level system with reduced HDF [harmonic distortion factor]

In most inverter/converter applications, the SVPWM method is the preferred approach, for it shows good characteristics in linear modulation range and waveform quality.

Summary:In most inverter/converter applications, the SVPWM method is the preferred approach, for it shows good characteristics in linear modulation range and waveform quality. In this paper, the authors propose a new carrier based SVPWM method for multi-level inverter systems. First, they survey the conventional carrier based SVPWM method, and investigate the problem of the conventional one for multi-level systems with the focus on the switching frequency harmonic flux trajectories. Finally, they propose a new carrier based SVPWM method that can reduce harmonic distortion. Simulation and experimental results are given to verify the proposed SVPWM method.
