Design Considerations for Mid-Power Receiver in Resonant Wireless Power Transfer System

Resonant wireless power transfer offers high degree of freedom for the receiver positioning, but it also has higher restraints on the design of the receiver circuit. This paper discusses design considerations for the design of the receiver circuit for applications in mid-power range (10-100 W) using resonant wireless power transfer system. Wireless power receiver circuit consists of three main sub-circuits: resonant tank, rectifier circuit and DC-DC converter. The impact of each sub-circuit is analyzed with respect to efficiency and overall performance of the receiver circuit. Results from the mathematical models and simulations are compared with measurements. The final design of the receiver circuit is implemented in LCD TV and evaluated through laboratory measurements.
