Wireless power transfer systems using near-field magnetic coupling are attractive as they allow power transfer with high efficiency and do not require an unobstructed path between transmitter and receiver. In this work a two coil wireless power transmission system is analyzed, including the driving amplifier, and a demonstration system is built and characterized. The system achieves 76% efficiency...
In the paper, the characteristics of magnetic resonance wireless power transfer (MR-WPT) system with two off-axis rectangular self-resonators are analyzed. Efficiency and mutual inductance method between two rectangular coils are obtained. Mutual inductance in an off-axis system is derived at an arbitrary spatial point by subdividing the Rx coil and summing the magnetic flux density of each subdivision...
In recent days the demand for saving energy consumption is increasing day by day. HEMS is expected as one of the useful technology to satisfy that demand. Though it is understood useful and used on some situations, it has not prevailed well into the public. The reason is considered to be high initial cost of the equipment, low mobility of the system and regrettable unconcern for saving energy. In...
A procedure to calculate parameters of an equivalent circuit of the magnetic-coupled resonant wireless power transfer is discussed. Equivalent circuit parameters are calculated from the mechanical and material parameters of the wireless power transfer structure. Both direct-fed type and indirect-fed type structure are considered. MoM calculation shows that the equivalent circuit has capability to...
