Abstract

This paper presents Pulse Width Modulation (PWM) control technique for three to seven-phase ac-to-ac power converters. These proposed PWM techniques are based on Indirect Space Vector Modulation (ISVM), which model the converter as two independent stages perform rectification and inversion stages. Two schemes of ISVM are proposed. The first scheme maximizes the voltage transfer ratio (VTR) of the converter but it produces unwanted low order harmonics. The second scheme generates sinusoidal output voltage waveforms; the cost is a reduction in the VTR of this configuration in linear mode. The viability of the proposed technique is proved using experimental results.
