With the widespread application of junction transistors in switching applications, the need for a general method of analysis useful in the region of collector voltage saturation has become apparent. Linear equivalent circuits using lumped elements have long been used for small signal calculations of normally-biased transistors, but a comparable method for saturated transistors has been lacking....

A novel, improved equivalent circuit model of double-sided linear induction motors (DLIMs) is proposed, which takes the skin effect and nonzero leakage reactance secondary, longitudinal, transverse end effects into consideration. Firstly, traditional with longitudinal are briefly reviewed. Additionally, correction coefficients for derived by one-dimensional analysis models given. Secondly, fact...

Abstract Lithium-ion batteries have become the primary battery technology used for electric and hybrid vehicles powertrains. Battery temperature, however, is a critical factor these devices, as it influences performance life-time safety must be preferably kept in 15-35 °C range. A dynamic electro-thermal model of lithium iron phosphate was developed. The predicts voltage temperature evolution d...
