Hardware implementation of fuzzy controlled isolated Zeta converter fed BLDC motor drive

A fuzzy controller based isolated zeta converter fed BLDC motor drive is proposed here. The non-linear load like rectifier with capacitor, adjustable speed drives etc add current spike and distorts the supply current. Due to this injected harmonics the quality of power degrades. Active power factor correctors are suitable for the harmonics caused due to the non-linear loads. Isolated Zeta Converter is a power factor corrector which can reduce harmonics, speed control and also provides isolation. The overall cost of this system is less due to the reduced number of sensors. The high switching frequency of the converter helps to reduce the component size. Fuzzy Logic Controller is used as it is suitable for parameter variation and simple control. So this system is simple, cost effective, provides better power factor and speed control.
