Single-transmitter and multi-receiver type wireless energy transmission device

A single-transmitter and multi-receiver type wireless energy transmission device of the utility model comprises a transmitter and at least two receivers, each receiver comprises a receiving coil, a load and a reception impedance matching network. A reception high frequency parasitic resistor is arranged in the receiving coil, one side of the reception impedance matching network is connected with the two ends of the receiving coil, and the other side is connected with the two ends of the load. The transmitter comprises a high frequency power source, a transmitting coil and a transmission impedance matching network, a transmission high frequency parasitic resistor is arranged in the transmitting coil, one side of the transmission impedance matching network is connected with the two ends of the high frequency power source, and the other side is connected with the two ends of the transmitting coil. Under the same distance, and compared with a conventional single-transmitter and single-receiver type wireless charging mode, the single-transmitter and multi-receiver type wireless energy transmission device has a charging characteristic of higher efficiency and power. Meanwhile, the more the receivers are, the higher the overall charging efficiency is.
