TRANSMITTING SYSTEM AND POWER RECEIVING DEVICE

PROBLEM TO BE SOLVED: To provide a transmitting system transmitting/receiving an electric signal by field coupling, the system stably and efficiently supplying power to a load resistor.SOLUTION: A transmitting system comprises a power transmitting device transmitting an electric signal, and a power receiving device receiving the electric signal in a non-contact manner. The power receiving device includes a load resistor, a coil part, a capacitor part, a first power receiving electrode and a second power receiving electrode, in which the first power receiving electrode, the coil part and the second power receiving electrode are series-connected in order, the load resistor is parallel-connected to a part or all of the coil part, and the capacitor part is parallel-connected to the coil part. The power transmitting device includes a first power transmitting electrode and a second power transmitting electrode, and transmits an electric signal to the power receiving device at an angular frequency determined by coupling capacitance of a first transmitting capacitor and a second transmitting capacitor, and capacitance of the capacitor part. The first transmitting capacitor is formed by the first power transmitting electrode and the first power receiving electrode. The second transmitting capacitor is formed by the second power transmitting electrode and the second power receiving electrode.
