In recent years, the wireless EV chargers have been spotlighted as convenient, safe, and clean apparatus. In this paper, proposed has been a newly developed large-gap wireless power transfer EV charger which can communicate control signal to a power feeding unit from a power receiving unit without any additional communication equipment. The wireless power transfer (WPT) system with a single-ended...
In this paper, a maglev transportation system with a Linear Induction Motor (LIM) is introduced. It is proposed that two different frequency components are used to achieve the simultaneous and independent control of the thrust and attractive force of LIM. One of the frequency components is synchronous with the motor speed (fm). The other frequency is drive frequency (fd) that generates the thrust...
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...
In this paper, a novel maglev transportation system of the Linear Induction Motor (LIM) is introduced. It is proposed that two different frequency components are used to achieve the simultaneous and independent thrust and attractive force control of the LIM. One of the frequency components is synchronous with motor (fm) that is used to control the levitation of LIM. The other frequency is drive frequency...
