PROBLEM TO BE SOLVED: To obtain a condition (circuit constant) for high-efficiency and safe non-contact power transmission by suppressing a calorific value and a generated voltage to a small value, and to realize the condition, particularly the thickness and the number of turns of a coil and a flow line. To grasp. First, (1) Kirchhoff's law is applied to obtain a circuit equation for a magnetically coupled resonant circuit, (2) the circuit equation is solved assuming that the power supply voltage is a sinusoidal wave, and (3) the target efficiency is achieved. (4) The size of the capacitor capacity that maximizes the transmission power is obtained. Next, the amount of heat generated and the capacitor voltage when transmitting a predetermined power in this circuit are obtained (safety is confirmed), and the coil size and copper wire thickness are obtained from the magnitude of the circuit current and the L value of (3). Find the theoretical value of. [Selection diagram] Fig. 1
