Wireless Charging System With a Non-conventional Compensation Topology for Electric Vehicles and Other Applications

Abstract

The proposed paper presents a 500 W, universal input, wireless electric vehicle battery charging system using a non-conventional compensation topology. An algorithm to compensate Loosely Coupled Inductive Power Transfer (LCIPT) systems with such topology is explained. The design and implementation of each power converter, as well as the coils manufacturing process, is briefly covered. Experimental results are shown to validate the expected system behavior. 

Wireless Charging of Electric Vehicle While Driving

“…Many researchers are working on how maximum power can be transferred to the receiving pad and increase the overall efficiency of EVs in dynamic conditions. But the efficiencies of most work are under 90 percent for RIPT also [7]. The other factor which is affecting the overall efficiency is misalignment while driving the EV.…”

Controle Preditivo do Conversor do Estágio Receptor de um Sistema de Transferência Indutiva de Potência

“…A Transferência Indutiva de Potência (Inductive Power Transfer -IPT)é uma forma de transferência de energia "sem contato"(Wireless Power Transfer -WPT ) muito pesquisada atualmente. Essa tecnologia tem sido considerada estratégica para o carregamento de baterias de veículos elétricos e equipamentos eletrônicos de uma forma geral (Griffin and Detweiler, 2012;Fernandes, 2015;Godoy et al, 2016;Li et al, 2017;Orekan et al, 2018). Em ambientes inflamáveis ou com presença deágua, a alimentação de equipamentos por contato elétrico pode ser insegura (Bingyi et al, 2005).…”
