英文摘要	This paper focuses on impedance matching issue for 2-to-1 (two transmitting (TX) coils to one receiving (RX) coil) coupled magnetic resonance (CMR) wireless power transmission system. It starts from discussing conventional 1-to-1 CMR system and its impedance matching issue. We then further studies the equivalent circuit model of a 2-to-1 CMR system and compares the similarity and difference between them. We consider the mutual inductance between two TX coils and analyze how it will affect the impedance of two TX coils. Based on this, we propose a method to solve the impedance mismatch problem in 2-to-1 CMR system and an automation scheme to automate the impedance matching process. An experiment is conducted to validate the proposed method. And the result shows that with the proposed method, system can respond actively to the impedance mismatch caused by the spatial movement of receiver in a 2-to-1 CMR system. The power transmission efficiency are all enhanced for both transmitting coils when the automated IMN is applied.
