Recently, the wireless EV chargers have been spotlighted because of safe, and easy use apparatus. Proposed has been a newly developed large-gap wireless power transfer EV charger which can communicate control signal to a power feeding from a secondary side with no communication equipment. The SEPP inverter WPT apparatus is designed for large-gap loose-coupling condition by characteristic-impedance...
In recent years, as an eco-friendly EV charging system, the wireless charging has become a topic due to the merits such as convenient, safety, and clean. In this paper, in order to realize a large-gap wireless charger which can communicate between the power feeding and receiving units without any additional communication device, a wireless power transfer (WPT) system using a single-ended push-pull...
The latest Electric Vehicles (EV)-related power electronics have attracted special interest as one of effective solutions to energy and environmental issues. In order to implement a promising EV battery charging equipment and its EMS infrastructures for carports in private houses and public buildings, Wireless Power Transfer (WPT)-based on-board chargers (OBC) are more suitable and acceptable from...

AC motor-driven electric scooters are highly eco-efficient, high performance, more convenient, and air-pollution free. They offer a certain powerful solution to global environmental and energy problems. This paper presents a newly-developed super-rapid charging electric motor-driven scooter (Electric Scooter) incorporating EDLC stack change-over power source. Described are practical design criteria...
This paper deals with a cost effective IPT wireless EV battery charger which incorporates the simplest quasi-resonant soft switching pulse modulated inverter. In the first place, the operating principle of the single-ended high-frequency resonant inverter linked IPT DC-DC converter treated here is described. This two planar coupling coils type wireless resonant DC-DC converter can efficiently operate...
