Wireless power transfer (WPT) has attracted a lot of attention these years due to its convenience, safety, reliability, and weather proof features. First and foremost, the consistency of mutual model and T model of loosely coupled transformer (LCT) was deduced. The application scenarios of these two models were then concluded so as to choose suitable model in circuit analysis. Then, a new WPT compensation...
This paper proposes a novel wireless power and data transmission (WPDT) scheme to meet the communication requirements in a wireless power transfer system. The scheme borrows the idea of power line communication which modulates a high-frequency data carrier into fundamental AC electric wave. The scheme provides a number of appealing characteristics, such as shared magnetic linkage, low cost, small...
This paper presents a magnetic coupling resonant wireless power transfer (MCR-WPT) system. Two separated coils form a loosely coupled transformer. The primary side adopts a Class-E amplifier, which produces high frequency sinusoidal current to excite the primary winding, inducting a high frequency AC voltage in secondary winding. The secondary side adopts a Class-E rectifier to rectify the high frequency...
Inductively Coupled Power Transfer (ICPT) attracts a lot of attention in recent years due to its convenience, safety, reliability and weather proof features. This paper proposes a novel ICPT compensation topology, named LC/P and consisting of an inductor, two capacitor and a loosely coupled transformer (LCT). Constant input voltage of LC/P compensation topology leads to constant output current under...
