As an environmental friendly vehicle, the increasing number of electrical vehicles (EVs) leads to a pressing need of widely distributed charging stations, especially due to the limited on-board battery capacity. However, fast charging stations, especially super-fast charging stations may stress power grid with potential overload at peaking time, sudden power gap and voltage sag. This project discusses the detailed modeling of a multi port converter based EV charging station integrated with DC power generation, and battery energy storage system. This project analyses the capability for Plug-in...

A Photovoltaic system, particularly in large power scenario is usually implemented in grid interconnected mode. In order to obtain a proper synchronization between grid and PV system, it is necessity to use control algorithms. In the first case an MPPT controller is implemented to extract maximum power from the PV systems and in second stage to control the transfer of active and reactive powers from the inverter and grid to load, it is necessary to estimate reference currents by using an adaptive filtering algorithm for this estimation. Therefore, in order to achieve effective grid...

This proposes a comprehensive methodology for the design of a controllable electric vehicle charger with PV system has capable of making the most of the interaction with an autonomous smart energy management system (EMS) in a residential setting. Autonomous EMSs aim is achieving the potential benefits associated with energy exchanges between consumers and the grid, using bidirectional and power controllable electric vehicle chargers. A suitable design for a controllable charger is presented, including the sizing of passive elements and controllers. The increase in the electric vehicle...

DC motors are widely used in systems with high control requirements. Thus, rolling mills, double-hulled tankers, and high-precision digital tools can be mentioned as examples of such systems. Generally, to control the step less velocity and smoothness, adjustment of the armature voltage of the motor is used; while, certainly, applying pulse width modulation (PWM) signals with respect to the motor input voltage is one of the methods most employed to drive a DC motor.

The proposed topology significantly reduces the number of dc voltage sources, switches, IGBTs, and power diodes as the number of output voltage levels increases. To synthesize maximum levels at the output voltage, the proposed topology is optimized for various objectives, such as the minimization of the number of switches, gate driver circuits and capacitors, and blocking voltage on switches. This new type of converter is suitable for high voltage and high-power applications. This multilevel inverter has ability to synthesize waveforms with better harmonics spectrum. In this project a study...
