Wireless Power Transfer Quality Factor

Resonators and their quality factors One of the essential factors in an efficient wireless power transfer system is the quality factor of the resonators.

Wireless power transfer quality factor. The wireless power is delivered to the load through the receiver coil reactive compensation and electronic rectification for DC loads. 1212016 devices such as cochlear implants. If Z 0 1 L i C i and Q i Z 0 L i R i represents the resonant.

1 Q L 1 Q r 1 Q eff 8 III. 10192015 Wireless power transfer is to transfer electrical power from one point to another through an air gap without any direct electrical contacts. CONCEPTS QUALITY FACTOR AND EFFICIENCY OF WIRELESS POWER TRANSFER Dr.

Ad A Forum for Original Research and Industrial Developments Relating to Wireless Power. Additionally the efficiency η can be calculated as. The link efficiency depends on the receiver coil compensation and the value of load resistance.

Management Jaipur Rajasthan 303807 INDIA Abstract The present text provides information regarding introductory concept of wireless power transfer through some of the existing technologies and evaluate its quality factor. 7 In order to achieve the maximum η the optimal load impedance Z L can be determined by differentiating ηwith respect to R and X L. The quality factor Q is related to the intrinsic loss rate 0 of the resonator by Q 2 0.

C two-port network model. Science IJOER Vol-1 Issue-1 March- 2015 CONCEPTS QUALITY FACTOR AND EFFICIENCY OF WIRELESS POWER TRANSFER Dr. To find the max Eff.

The unloaded quality factor of the resonator is typically limited by the quality factor of the coil and can be described with QT ωLT RT and QR ωLR RR for the transmitter and the receiver. Q2input n quality factor in the secondary side. 1282016 Quality factor Q is often used in WPT analysis but developers must exercise care in dealing with definitions of series parallel loaded or unloaded Q values Coupler alignment can be achieved using a variety of methods.
