Abstract

Wireless power transmission based on magnetic resonance for endoscopic devices is analyzed. The wireless power transfer system is composed of four coils, in which the driver and transmit coils are large coils around the waist, and the receive and load coils are small coils in body. The effect of the distance of every two adjacent coils, and the turn number of the load coil on the power transmission is investigated. The results of the two-coil system based on conventional electromagnetic inductive coupling are also shown for comparisons. The high transfer efficiency and low voltage across the driver coil of the wireless power transmission based on magnetic resonance for endoscopic devices are theoretically verified.
