Among the factors slowing down the production of the electric vehicles in big series, we mention the problem of weak autonomy directly bound to the weak storage capacity of the batteries. In this context, this paper describes a strategy of power chain vector control reducing the consumption and integrating a system of energy recuperation. Besides, this power chain is conceived by an analytic ap...

This paper describes a large-signal linear, multirate digital controller for, among other possible servomechanical applications, charging electric vehicle batteries. This controller permits the power amplifier to track and deliver a desired current trajectory for a wide range of loads while providing a unity-power-factor interface to the electric utility. A computationally inexpensive technique...

This paper explained about switching losses in prescribed circuit. Batteries are the primary energystorage devices in ground vehicles. Now-a-days battery fed electric drives are commonly being used for electric vehicles Applications, due to various advantages, such as nearly zero emission, guaranteed load levelling, good transient operation and energy recovery during braking operation. To full ...

A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltagecurrent characteristics, while achieving low part number and bi-directional operational. The Multiple-input converters have many applications such as grid connected integrated hybrid generation systems, fuel cells, micro grid-based tel...

The growing interest in the development of electric vehicle charging system based on expanding green car market is to meet the system demand for high efficiency and high density output characteristics. In addition, according to increase the in-production of electric vehicle, it is going to increase developing plan for on board charging system in around the world. In this paper, the charge contr...

Electric machines are driven nowadays by static system popularly known as soft starter. This paper describes a thyristor based static frequency converter (SFC) to run a large synchronous machine installed at a short circuit test laboratory. Normally a synchronous machine requires prime mover or some other driving mechanism to run. This machine doesn’t need a prime mover as it operates in dual m...

This paper presents a hybrid cascaded H-bridge multilevel motor drive control scheme for electric/hybrid electric vehicles where each phase of a three-phase cascaded multilevel converter can be implemented using only a single DC source and capacitors for the other DC sources. Traditionally, each phase of a three-phase cascaded multilevel converter requires n DC sources for 2n + 1 output voltage...

The growing attention for plug-in electric vehicles, and the associated high-performance demands, have initiated a development trend towards highly efficient and compact on-board battery chargers. These isolated ac–dc converters are most commonly realized using two conversion stages, combining a non-isolated power factor correction (PFC) rectifier with an isolated dc–dc converter. This, however...
