An Efficient Wireless Power Transfer System for EV Charging Using High-Frequency Resonant Inverter
In the world, Electric Vehicles (EVs) are a promising technology for developing a sustainable transportation sector because of their extremely low to zero carbon emissions, low noise levels, high efficiency, and flexibility in grid operation and integration. Thus, the number of EVs in use is growing annually. In recent years, Wireless Power Transfer (WPT) systems have been utilized as EV battery chargers. Designing effective power electronic converters enables the WPT system to operate at high frequencies, which is a typical feature for transmitting large amounts of power over longer distances. Therefore, this paper proposes a WPT system based on an efficient high frequency inverter for an EV charging system. A high frequency inverter decreases the size and resistance of passive components like inductors and is utilized for operating more effectively than a low frequency. The primary function of an isolation transformer is to provide electrical isolation between the high voltage battery and the low voltage systems.

Further, a PI controller helps maintain stability and optimal performance. The MATLAB/Simulink simulation indicates that the proposed system has improved switching losses, reactive power compensation, and the highest efficiency of 98%.
Energy-Efficient Routing in MANET using Mountain Gazelle Optimizer and LEACH-Based Clustering
The rise of Internet of Things (IoT) applications and the widespread use of mobile devices have made Mobile Ad Hoc Networks (MANETs) more important in modern day. Enabling effective data transport in decentralized wireless networks is largely dependent on the routing mechanism. In the present research, Mountain Gazelle Optimizer (MGO) is integrated with Low Energy Adaptive Clustering Hierarchy (LEACH) protocol to offer an effective routing and clustering framework for MANETs. Intelligent approaches are necessary for dependable data transmission and energy conservation in MANETs due to their inherent mobility and dynamic topology changes. To overcome these obstacles, the LEACH protocol is used for energy efficient and adaptive clustering, in which cluster heads are chosen at random to distribute energy usage among nodes. The Mountain Gazelle Optimizer, an evolutionary algorithm modelled after the adaptive movement behavior of gazelles, is used to optimize routing between cluster heads and destination nodes. By reducing parameters like energy usage, transmission latency, and route instability, MGO optimizes the routing paths. When compared to conventional methods, the proposed MGO LEACH model improves Packet Delivery Ratio (PRD) and network lifetime and lowers routing costs. The proposed design greatly enhances MANET’s performance, as shown by extensive simulation findings, which makes it ideal for dynamic and energy constrained wireless network situations.
