Abstract

This paper proposes a generalized space vector pulse width modulation (SVPWM) technique for hybrid multilevel inverters for minimizing total harmonic distortion (THD). The proposed method easily determines the actual location of the instantaneous reference space vector and the corresponding switching sequence of a multilevel inverter. The proposed algorithm offers a novel method for minimizing the total harmonic distortion (THD) of the output voltage of the inverter and uses simple arithmetic for determining the sector and does not require lookup tables. The proposed method can be extended to any n-level inverter, and a generalized algorithm is also proposed. Finally, the algorithm was implemented on a Digital Signal Processor (DSP) and the scheme is explained for a five level inverter, and experimental results are presented for a seven level inverter.
