voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. this phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. in this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

This article presents a new ultrawideband wide-angle scanning tightly coupled dipole array loaded with multilayer metallic strips. The strips, which is composed of several narrow strips different lengths, are used to equivalent the metal patch has specific shape. It can help achieve smoother impedance transform from free space. An circuit model (ECM) unit cell proposed analyze and design array....

In the process of battery system design and operation, accurate battery modelling is a key factor. Generally speaking, the electric characteristics of a given battery cell are necessary for a designer to build an equivalent circuit model. The equivalent circuit design entails the creation of both the sizing of components used in the circuit and the topology. So, it is very hard to build an accu...
