Abstract

The paper describes the theory of voltage space vector PWM in three-level inverter. The necessary and sufficient conditions for waveforms, such as synchronization, three phase symmetry (TPS), half-wave symmetry (HWS) and quarter-wave symmetry (QWS) are presented. Different strategies and realization methods are introduced. Simulation waveforms of voltage, current and corresponding harmonic spectrum are offered. The comparative results show that simulation results with proposed methods is in accordance with the experimental results seriously.
