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.

Wind and solar hybrid generation is now being used as a prospective generation scheme especially for remote and grid isolated areas. This paper presents an analysis of wind-photovoltaic (PV) hybrid generation scheme to be used in isolation from the grid for managing irrigation and supplying some other critical loads. The proposed generation scheme can be used to generate power with varying wind speeds. The load voltage will be maintained using availability of power from wind or PV sources. The proposed scheme can be installed in a hilly region or in any onshore areas which is isolated from the grid. The proposed scheme is also flexible to be connected to grid if required. The control is done using a smart controller. The simulation and experimental results validate that the proposed hybrid generation can be suitably used, installed and employed for isolated power generation effectively especially for irrigation management.

Power electronic devices plays major role in controlling and improving the drive system. because of the robustness, good performance and solidness of an induction motor it is highly recommended for the industrial application. In order to obtain better performance from this kind of motors we use converters to control the motor with input parameters. But when we use the power electronic elements there is high chance of failure of this elements. This failure may lead to short-circuit fault, open-circuit fault and many other which may occur in DC link in converter of drive system. Short-circuit faults in converters will make big differences in every parameter and we have our normal conventional methods to deal with it. But open-circuit faults make system run at low efficiency and these faults are unable to find immediately. Neglecting these kinds of faults may lead to damage the other elements in the system. So, in this paper diagnosis models for the open-circuit faults in inverter fed induction motor using machine learning models and multilayer perceptron classifier is presented. In this model RMS currents and RMS voltages of each phase have been considered as a feature by which models have been trained and also valid simulation test results provided.

The Internet of things (IoT) is one of the most revolutionary technologies leading experts have created today. The ever-increasing number of devices and embedded systems has made it a necessity for IoT to be implemented in every corner of the world. The latest technology for electric vehicles uses IoT monitoring and life cycle management. Even though there is a sophisticated battery management system in the present Electric Vehicles, there is always a chance of battery damage due to numerous instances caused by battery overcharge and exposure to high/low temperatures. It may prevent battery damage if the battery level is indicated well in advance, similar to “reserve” in the petrol car. In this paper, battery monitoring is implemented using IoT and MQTT protocol based on the battery levels, and the navigation to the nearest available charging station is also displayed.

This article proposes a multi-level converter topology (MLCT) for a four-phase switched reluctance machine (SRM) drive-based electric vehicle (EV) application with auxiliary load driving capability. The proposed MLCT employs the same number of devices as in the conventional three-level-asymmetrical half-bridge (CTL-AHB) converter. The DC-link in the proposed MLCT topology is connected in series with an active boosting source, i.e., battery, via a bi-directional DC-DC converter to achieve higher voltage levels. The higher voltage levels result in faster energization and de-energization of the phase currents, resulting in improved average torque output. The proposed MLCT provides continuous power to the auxiliary loads for EV applications via a series battery. Depending on the series battery voltage/state of charge, the operating modes of the converter allow its charging via three modes. Analysis of different operating modes under motoring and regeneration/ braking is discussed with the simulation and experimental validation of the same.

Double-excited AC machines, such as PMSMs, provide fast torque responses and great operating performance. Permanent magnet synchronous motors have an increase in electromagnetic torque that can be demonstrated analytically. Direct Torque Control (DTC) adjusts the angle between the stator and rotor flux connections to achieve rapid torque response. Electrical torque is calculated in a stationary reference frame using DTC’s calculations for electromagnetic torque. Stator flux and torque are variables. There are a variety of techniques for determining the rotor’s location and speed without the use of sensors. As an improvement on standard DTC, a sensor-less approach for detecting rotor position and performing direct torque control will be discussed in this work. MATLAB findings are used to model the sensorless direct torque control technique’s fundamental operation.

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.
