Abstract

This paper deals with an active front-end converter (AFEC) for a 5-ϕ inverter-fed induction motor (IM) drive. Multi-phase IM drive stands as an evolving domain of electrical drive usages. Supply from the grid is prone to be unbalanced and affects the input power quality of adjustable multi-phase IM drives. This work proposes a fuzzy logic control strategy with the space vector pulse width modulation (SVPWM) switching scheme for the AFEC outer voltage control along with inner current control loops for attenuating the disturbances due to voltage unbalance conditions. This method of control can keep the power factor nearby unity on the AC side with sinusoidal AC current and constant DC voltage at the DC link capacitor. A 5-ϕ inverter designed with SVPWM for IM drive enables operation of the drive with reduced percentage total harmonic distortion (THD) in the voltage of output side. This SVPWM control for a 5-ϕ voltage source inverter (VSI) uses entire voltage of the DC bus and the output responses are more efficient having a minimal lower order THD. The dynamic performances of a 5-ϕ VSI fed IM drive are investigated. The simulation results show the system has an improved power factor at the front-end, constant DC voltage across the capacitor, low THD at the input current, and a superior output performance for the 5 phase IM based drive.
