Design and Implementation of Different Drive Topologies for Control of Induction Motor for Electric Vehicle Application
(River Publishers, 2022) Husain, M.A.; Rajput, R.; Gupta, M.K.; Tabrez, M.; Ahmad, M.W.; Ilahi Bakhsh, F.I.
To improve driving range in Electric vehicles (EV), parallel-series connection of battery cells is a necessity. Supressing the circulating current in the battery board of parallel connected battery strings helps improve the lifespan of the batteries. This study presents a comparison of the requirements of parallel strings of batteries in three different popular topologies for open end winding induction motor (IM) drives in EV. The topologies analyzed are a 3-phase voltage source inverter (VSI), a Dual fed inverter and three single-phase HBridge VSIs. These converters are modulated using Space vector pulse width modulation (SVPWM) as it has better performance compared to Sine PWM. MATLAB-Simulink models are developed for the converter topologies. The simulation results show that the three single-phase inverter topology feeding the drive is the best alternative when compared on the basis of battery requirement and switch loss. Moreover, each H-bridge inverter (in the three single-phase inverter topology) can be used as charger and the problem of circulating current during charging will also be least as compared to other schemes. © 2022 River Publishers.
Trusted partner selection in broker based cloud federation
(2017) Gupta, M.K.; Annappa, B.
Cloud federation is a group of aggregated providers, who are mutually cooperating and collaborating to share their resources in order to improve each other services. It has lured the attention of commercial industries towards itself for its effective utilization of cloud resources. Effective management of the resource is very much required in order to increase the profits of an individual service provider in federation, but a lack of proper business model hinders service provider in deploying its feature. In this paper, cloud federation is created based on intelligent, trusted broker. It opens a possibility of borrowing the resources from foreign clouds and deliver quality of service as promised by them. Trust factor is used in the paper to classify the foreign clouds according to previous performances and its neighbouring recommendations. Foreign clouds can only take participation, if it is approved by the broker. Furthermore, broker enforces foreign clouds to participate in the federation and behave reliably. � 2016 IEEE.
