碩士 === 長庚大學 === 電子工程學系 === 104 === This paper is divided into two parts. The first part mainly introduces how to calculate the model parameters of the solenoid coil, including inductance, capacitance, resistance in high frequency. And the self-vibration frequency of a coil, this is very important. The wireless charging frequency can’t exceed the self-vibration frequency of the coil. The second part is the introduction of traditional wireless charging architecture magnetic induction 2-coil and magnetic resonance 2-coil, including the relationship between transmission efficiency and transmission power and coupling coefficient. In order to achieve longer distance and more high power, we use the multi coil transmission. The traditional 4-coil and the new 4-coil architecture can improve the distance and improve the traditional 4-coil attached to receive power. Experimental measurement aspect to how to use a better method to measure the parameters (inductance, resistance, capacitance), precise measurement of the coupling coefficient. And when we are face with the problem that our coil isn’t accurate resonance, how to solve it.
