Wireless Photovoltaic Power Transfer Based on DC-DC Converter for the Application of Battery Charger System

Abstract

Typically, a wire is used to convey electrical energy from the sending terminal to the receiving terminal. Higher electrical energy demands larger cable sizes, which raises costs and has less-than-exciting technical implications. Additionally, a wired electrical system is unsuitable in a small space. So, in the needed region, a wireless photovoltaic power transfer (WPVPT) system is implemented. In this paper, a WPVPT system based on a DC-DC boost converter for a battery charger system application using MATLAB SIMULINK is presented. In order to attain a longer distance and greater power, the distance between the transmitting and receiving coils as well as the AC voltage on the transmission are taken into consideration using mathematical modelling. According to the simulation results, 35 PV modules connected in series are needed to keep the DC-DC converter's output voltage at 14.81 V and its output power at 50.77 W while it is charging a 12 V, 1. 2 Ah battery. The battery will require 1000 s to reach its completely charged condition if it begins the charging process with a state of charge (SOC) of 25%.
