Abstract:

The operating principle for the neutral-point-clampped three level inverter was proposed. To overcome massive computational problem based on rectangular coordinate system, a simplified method was addressed for SVPWM based on coordinate system. The method of simplifying small area was used to reduce complicated calculation, so that the control method is more concise. The method is verified by MATLAB and hardware circuit experiment.

Key words: three-level inverter, space vector pulse width modulation (SVPWM), coordinate system
