Fuzzy logic current controller for three-phase voltage source PWM-inverters

A fuzzy control scheme for three-phase sinusoidal current controlled space voltage vector modulation voltage source inverter is implemented in this paper. This fuzzy controller demonstrates improved response than conventional PI controller and is chosen as a better alternative. The simulation results confirm the validity of the proposed fuzzy controller for three-phase voltage-fed inverter for both induction motor load and inductive load. The digital implementation of space vector modulation technique is illustrated with the switching topology that yields reduced switching losses.
