Abstract :
This paper presents a fuzzy logic control scheme of space vector pulsewidth modulation (PWM) for three-phase power converters. The conventional space vector PWM current regulator implementation is generally computationally complex. The fuzzy logic controller implementation relieves the processor of a number of computations, thereby accommodating a less expensive microprocessor. The AC side rectifier voltages are used as fuzzy state variables. The fuzzy logic control has two outputs: magnitude; and angle of reference voltage. Both conventional space vector PWM and the fuzzy logic controller are implemented to evaluate performance using 16-bit microcontroller (68HC16). Experimental results are provided for both controllers at the same operating point, where the power drawn by the load is about 3 kW. The fuzzy logic controller reduces the computational burden on the processor by about 30%
