Abstract

The space vector pulse-width modulation of voltage source inverter is widely used because it easily realizes the desired voltage vector, but the output voltage of the space vector pulse-width modulation of voltage source inverter has considerable error, particularly in the low output voltage command. This paper investigates a high-performance strategy, where a variation of the dc-link voltage is used for an improved output voltage in the space vector pulse-width modulation of voltage source inverter. The variable dc-link voltage leads to an improved resolution of the inverter output voltage. Simulation and experimentation have been performed to verify the presented strategy.
