In this work, design, development and analysis of a closed loop-based control strategy of a fuzzy adaptive controlled PWM operated Permanent Magnet Synchronous Motor drive has been established. The entire structure of the proposed closed loop model is made up of two loop control formation, outer loop speed and inner loop current. Therefore, to enhance the dynamic operation of the drive system classical PI controller is taken as current controller and fuzzy adaptive controller with simplified fuzzy rules have been utilized as speed controller. With the implementation of sinusoidal PWM control strategy, it is evident that the nature of armature current would be nearly sinusoidal and generated torque ripples will be lesser. The detailed dynamic performance of a permanent magnet synchronous motor drive is carried out in MATLAB/SIMULINK environment. An economic as well as efficient inverter configuration is also proposed in this article. The simulations results confirm the effectiveness of the proposed approach. The outcome of the proposed concept can be utilized for dynamic performance prediction of a light electric vehicle in a modern energy efficient environment

AbstractThe present status of SiC high-voltage power switching devices is reviewed. The figures of merits that have been used for unipolar and bipolar devices to quantify the intrinsic performance improvement over silicon are presented. Analytical and numerical modeling and simulations to estimate the BV and device choice are described. The active area and termination design of trenched-gate MOS power transistors, together with an integrated process for their fabrication, is presented. The progress in high-voltage power device experimental demonstration is described. The material and process technology issues that need to be addressed for SiC device commercialization are discussed. Finally, the impact of SiC power devices on motor drive systems is estimated.
