Electronics Nuclear engineering In this thesis, a technique based on V/I maximum attainable efficiency method is proposed for operating an IM with V/f controller at maximum attainable efficiency at partial loads. The technique requires estimation of V/I reference value (V/I) corresponding to maximum attainable efficiency at a given load using IM equivalent circuit parameters. Analysis and theoretical validation of the technique has been carried out using IM equivalent circuit. Experiments were carried out in the laboratory using a PWM inverter fed fractional horsepower SCIM with a V/f controller (specially developed and fabricated) at a few selected loads at rated frequency. The supply voltage to the SCIM was varied for the selected loads and the corresponding V/I values were calculated by measuring V and I at stator terminals. The efficiency for various values of V/I were plotted for the selected loads. It has been found from the graphs that for a given load, the maximum attainable efficiency occurs at a value of V/I closer to the calculated (V/I)ref. The results thus validate the concept proposed. 2012-03 Thesis http://shdl.mmu.edu.my/5582/ http://library.mmu.edu.my/diglib/onlinedb/dig_lib.php phd doctoral Multimedia University Faculty of Engineering and Technology
