Typically, renewable energy offers clean energy along with effective and optimal utilization on comparing other conventional sources of energy. On relating other renewable sources, solar photovoltaic (PV) based generation of power is accessible readily. This is employed widely for charging, lighting, and pumping of solar and so on. The issue associated with energy is minimized by using pollution-free renewable sources of energy without having emission and the maximum output power is attained using optimization process. For this purpose, this article presents a SEPIC based DC-to-DC converter design with the soft switching operation for the wide conversion operation of E-Automobiles. The solar PV source is given to boost converter with the use of Hierarchical Multi-Heuristic Chicken Swarm Optimization (HMH-CSO) based Maximum Power Point Tracking (MPPT) scheme. The converted source is given to SEPIC converter at which the Fuzzy Logic Controller (FLC) is employed. A SEPIC converter is a DC-to-DC converter that converts the fixed range of DC supply to the variable range of DC supply using duty ratio. The zero-voltage source (ZVS) soft switching operation of converter is provided. The converted output is inverted by means of three-phase inverter at which the generation of pulse width modulation (PWM) is made by means of FLC controller employed. The inverted output is given to the load (BLDC motor) by filtering using Low Pass Filter (LPF). Thus, an efficient generation of power is made and is given to the load of BLDC motor side. The performance analysis is made for traditional PID (Proportional-Integral-Derivative) controller and FLC controller and the outcomes attained for both controllers are compared to show the efficiency of proposed FLC controller. The performance is estimated in terms of Rise time, peak time, peak overshoot, settling time, delay time, output voltage, output current, and steady state error. The comparative analysis shows that proposed design using FLC controller offers better outcome than others.

With the increasing deployment of the electric vehicles, the study of advanced battery charging strategy has become of great significance to improve charging performance with reduced loss. This paper presents an optimized adaptive charging strategy for EV battery packs based on a developed system loss model. An electrical model integrated with thermal properties for the lithium-ion battery with cooling as well as a full loss model for the power converter have been included in this complete model. To reduce the overall loss of the charging system, the influence of temperature and varying internal resistance at different state of charge (SOC) have been considered to obtain an objective function. Moreover, an enhanced particle swarm optimization (PSO) algorithm is proposed and applied to speed up convergence time as well as enhance the precision of the solution. The results show that this proposed strategy can reduce the total loss by 4.01% and a 7.48% decrease of the charging time compared with the classical approach without applying this optimization.

Current fed solid-state transformers (CF-SSTs) offer substantial weight and size reduction advantages over 50/60Hz traditional transformers. CF-SSTs have low source current ripple which makes it suitable for the connection of large batteries in the medium voltage grid. However, power losses are high compare to the traditional one due to the high operating frequency range. Therefore, power losses calculations are the main key to select the main design parameters. Unlike most of the published work dealing one aspect of power losses or a specific element and only consider voltage fed Solid State Transformers topology (VF-SSTs), this paper presents a power losses calculation method for CF-SSTs considering all the power losses, the shape of the voltage waveforms, cores dimensions and manufacturer datasheets are main paper pros. ANSYS and Matlab Simulink are employed to validate the analytical equations. Due to simplicity, this method can be used for optimization.
