Abstract

Abstract: The transmission performance of wireless power transfer is highly influenced by the mutual inductance (M) between the transmitter and the receiver. This paper proposes a mutual inductance estimation method for the multiple input coils wireless charging system which can be used in low-power portable devices such as mobile phones. The method can estimate M precisely and reliably without using empirical formulas and additional communication system. It simplifies the estimation process and achieves more accurate values of M under any conditions. Simulations and experimental results prove the proposed method has a good performance on estimating M at any circumstance.
