WPT system based on U-shaped coil positioning assistance and position guiding method

The invention provides a WPT system based on U-shaped coil positioning assistance and a position guiding method, and the system comprises a DC power supply, an inversion module, a primary side compensation topology module, a transmitting coil, a receiving coil, a secondary side compensation topology module, a rectification filter circuit, and a load. At least three U-shaped coils are arranged below the transmitting coil and are close to each other end to end in sequence to form a polygon, the transmitting coil is arranged on groove areas of the at least three U-shaped coils, the two ends of each U-shaped coil protrude upwards from the edge position of the transmitting coil, and each U-shaped coil is further connected with a positioning auxiliary resonance compensation network. The input port of the primary side compensation topology module and the input ports of the plurality of positioning auxiliary resonance compensation networks are connected in parallel with the output end of the inversion module, and are
