Dynamic Wireless Power Transfer for Electric Vehicles With Dc-Dc Buck-Boost Converter

Abstract

Wireless Power Transfer (WPT) enable a viable means of charging Electric Vehicles (EV)’s whilst in a dynamic state will called as dynamic state based whilst wireless power transfer(DWPT), it justifying problems regarding vehicle range, the network dissemination of static based charging systems, and the size of on-board energy storage. Dynamic wireless charging of electric vehicles (EVs) is becoming a favoured process since it allows power exchange among the vehicle and the network while the vehicle is moving. The unbalanced output voltage, power parameters, and current, which are common for such schemes, can be alleviated by including a DC-DC converter and a controller into the process. In this paper, analyses the performance of the Proportional-Integral (PI) feedback controller and a Fuzzy controller, which are employed to control the result of the Buck-Boost converter of the wireless charging systems (WCS) for EVs. The suggested WPT process under deliberation is simulated using a graphical programming situation. It was exposed that both controllers expressively decrease the power pulsation.  However, PI controller reduces the power pulsation ratio from 40% to almost 0% after 0.45 s, whereas Fuzzy controller decreases the power pulsation ratio from 40% to nearly 5% after 0.09.
