Title:
METHOD AND SYSTEM FOR SELECTING OPTIMAL TRANSMISSION END COIL CURRENT AND RECEPTION END COIL GROUP IN MAGNETIC RESONANCE WIRELESS POWER TRANSMISSION MULTI-COIL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/135440
Kind Code:
A1
Abstract:
A method and a system for selecting an optimal transmission end coil current and reception end coil group in a magnetic resonance wireless power transmission multi-coil system are disclosed. The method for selecting an optimal transmission end coil current and reception end coil group in a magnetic resonance wireless power transmission multi-coil system, presented in the present invention, comprises the steps of: setting the same resonant frequency of a transmission end and a reception end and obtaining a reception end coil current, a transmission end coil current, a transmission end coil voltage, and transmission and reception power; limiting minimum reception power, a maximum transmission end voltage, and a maximum transmission end current in order to minimize transmission power from the transmission end to the reception end; and obtaining optimal reception power, an optimal transmission end coil current, and an optimal reception end coil group for a reception end coil set.
