Bidirectional Dual-Active bridge (DAB) DC-DC converter is one of the emerging technologies to be used in Electric vehicle charging and renewable energy application like solar cell, fuel cell etc., where stepping up/down of DC voltage is required. As DAB is operated at higher switching frequency switching loss is very high. By using resonant converter topologies of DAB soft switching is achieved and switching losses are reduced but starting current through inductor and starting voltage across capacitor is very high. In this paper, design and modelling of 207/48 V,3000 W bidirectional DC/DC DAB Series Resonant Converter is done; open loop soft starting algorithm is used for starting in LC type series resonant converter DAB and CLLC type series resonant converter DAB to reduce the high transient currents through resonant inductor and high transient voltage across resonant capacitor, comparison of peak currents and steady state currents are made.

This paper provides effective power quality improvement and DC offset removal for dual stage single phase grid connected solar photovoltaic (PV) system by incorporating adjustable frequency generalized integrator (AFGI) filter. The system also complements the maximum power output of solar PV array using driftless perturb & observe (P& O) maximum power point tracking (MPPT) technique and addresses the drift problem at varying insolation levels. This control provides satisfactory frequency estimation under the conditions of distorted grid voltage and varying grid frequency. The phase locked loop (PLL) less control not only improves the system dynamics and makes it robust, but it also facilitates it to exploit the system resources during the unavailability of sun irradiance and fulfils the load requirement of reactive power as well as harmonics compensation for local loads. The system is analyzed under various dynamic conditions of grid voltage distortion, DC offset, grid voltage swell, PV power variation, load variations using a developed Simulink model. The system complies with the IEEE-519 standard, eliminating the grid current deformations and maintaining a sinusoidal shape at real time fundamental grid frequency.

High reactive power burden, load unbalances, and current harmonics in a distribution line result from the widespread usage of non-linear nature of power electronic components. FACTS devices are introduced to maintain a sinusoidal supply to the end customers; among them, all Shunt active power filter (SAPF) can dynamically adjust current-based power quality concerns by providing harmonic components of load currents in shunt mode at point of common coupling (PCC). This paper explores the SAPF performance for a three-phase system using instantaneous active and reactive power theory (IRPT or p-q theory), synchronous reference frame theory (SRF or d-q theory) for correction of reactive power, Harmonic removal using direct current control method. To further enhance its performance in terms of dc link capacitor profile over robust Sliding Mode Control, a new controller named synergetic controller is proposed for this SAPF. For the validation purpose, simulation results have been captured on the MATLAB Simulink environment using Simpower system toolbox. The results proven that the SAPF with synergetic controller able to reduced current ripples on dc link capacitor and also improves the dynamic response of voltage by offering better THD.

Because of their great efficiency, inexpensive, and compact size, and transformer-less photovoltaic (PV) inverters are becoming increasingly popular. Active power injection with no leakage current is now possible because to new layouts and modulating approaches. Reactive power injection by PV inverters into the utility grid is now required under some new grid standards. To gauge the degree of difficulty, a new hybrid modulation approach is devised and tested on a non-isolated H6 topology. With relatively slight alterations to variable reactive power generation with minimum crossing distortions can be achieved using switching patterns and a phase shift in the reference current and avoid common mode voltage. In-depth explanations of the various modes of operation and design considerations for the new hybrid modulation approach are provided. A 4kVA prototype and the SMPLIS simulation provide ample evidence to back up the proposed hybrid modulation strategy.

A two-stage battery charger for the low voltage electric vehicle (LVEVs) is presented in this study. The presented charger utilizes a bridgeless version of an AC-DC converter having features of high gain and high-power factor along with continuous input current and comprehensive operational range capability at its front end. Whereas, at its back end, an isolated Cuk DC-DC converter is employed to control and implement different modes of battery charging, viz. constant current (CC) and constant voltage (CV) charging profiles. The presented AC-DC converter inherently achieves improved power quality at AC mains while operating under discontinuous current mode (DCM) operation and, therefore, incorporates minimum control complexity at the AC-DC stage of the charger. Thus, the DCM design and high voltage conversion ratio allow it to function reliably over a comprehensive range of input and intermediate DC link voltage, enabling the presented charger to deliver a wide battery voltage range at its output. In this work, the overall operational analysis and performance validation of the presented two-stage charger are carried out.

The consumption of energy in the universe was utterly raising persistently. So, due to this utter raise in the demand, we prefer to fossil fuels like coal, oil & natural gas to support the raise in demand, but these reserves may quickly drain in the future to change the world as green environment. So, supply and demand leads to disequilibrium case to beat the energy demand. For this we have to look on for alternative energy sources which comes under RE. The Solar, Wind, Hydro and some other existing sources are available copiously at hand to recoup for enlargement/growth of further increase in energy demands. The renewable energy sources which we are using individually may leads to pitfall in overall performance. To reduce in this pitfall issues the well-organized way is that to collaborating the individual renewable energy resources to attain better performance to overcome from few drawbacks. This tracing tactic can be convenient for both renewable sources like solar as well as wind for generation of power and rising their equivalent ability. By using MPPT controllers in supporting to WECS the maximum power can be traced. Compatibility of multi controllers such as FLC/SMC, FLC/MPC, SMC/PID, SMC/MPC makes the system performance will along with a two set of multi converter combination such as cuk-sepic, zeta-sepic, z-source can make assure that supports the hybrid pv-wind system to carry out well in crucial situations mentioned as less DC voltage flickering, overcome issues raised due to ripple current, control harmonics, improve Power Factor of AC lines, continuous input current, switching stress can be lowered, power efficiency can be improved.

Controlling the effect of slip-slide by adjusting the motor torque in both powering and braking modes respectively is critical for improving the performance and stability of rail propulsion systems on low friction surfaces. An adaptive wheel slip-slide detection and correction system has been designedfor a railway electric vehicle. The system controller demonstrates a simple design with a single parameter detection scheme with anti-jerk control and operates on the fundamentals of adhesion characteristics. The proposed control system has been employed and tested in a MATLAB-SIMULINK environment on a vehicle body driven by an asynchronous induction motor. The controller effectively reduces the applied reference torque to the motor control for auto correction following the detection of slipslide. The provided analysis results show that the sliplslide controller can give better performance and increased efficiency.

With DC microgrids (DC MG) gaining attention, virtual inertia (VI) schemes for stabilizing the system voltage become increasingly important. With decreased inherent energy storage, conventional droop control causes severe fluctuations in the DC bus voltage. Hence, this paper proposes a VI scheme that emulates inertia by attenuating and low-pass filtering the converter’s capacitor current. Since the capacitor’s current is directly proportional to its rate of change of voltage, attenuating the capacitor current restricts its voltage change which would otherwise occur with higher capacitance. Thus attenuating the capacitor current virtually increases the system capacitance. However, since practical capacitors have some parasitic equivalent series resistance (ESR), attenuation of capacitor current cannot guarantee a distortion-less inertial response when ESR is high. It was found that cascading a low pass filter of time constant governed by the capacitance and ESR can compensate for its impact. Time-domain simulations performed in MATLAB/Simulink and experiments carried out in laboratory-scale setup validate the effectiveness of the proposed VI scheme.
