Design and Simulation of Fuzzy Logic Based Speed Control for an SPWM Inverter-fed Induction Motor Taking Core Loss and Stray Load Losses into Account
Abstract: Speed and torque of an induction motor need to be controlled in order to achieve smooth control application. Field oriented control aids this factor and enables independent control of speed and torque by establishing an independent relationship between motor parameters. This complex relationship is developed due to consideration of core loss and stray load loss while modeling an induction motor. These two negligible but important parameters are neglected in most …

Suitability of Various Low Power Strategies for SRAM Design: A Survey
Abstract: In very high performance system on chip, static power dissipation plays a dominant role compared to dynamic component and it increases with technology scaling. Scaling of bulk MOSFET faces more and more challenges at 45 nm technology or below by producing short channel effect (SCE) which leads to increase in leakage current. An obstacle with bulk MOSFET at 45 nm or below gate length includes SCE, subthreshold leakage and gate …
