The invention provides a non-resonant end inductance compensation circuit and a non-resonant coil extension cord of a wireless charging system, the non-resonant coil extension cord is characterized in that two Litz wires are wound to form a flat and tightly arranged conductor as an internal lead, and a grounding copper net and an insulating layer are coated outside the lead, so that current is effectively increased, and the service life of the non-resonant end inductance compensation circuit and the non-resonant coil extension cord is prolonged. And radiation is reduced. The non-resonant end inductance compensation circuit comprises the non-resonant coil extension line, and two ends of the non-resonant coil extension line are respectively connected with the transmitting end non-resonant coil and the transmitting end control circuit, so that the inductance compensation circuit is utilized to carry out inductance compensation on the transmitting end non-resonant coil to meet the requirement of magnetic type wireless charging; and the problem of unstable charging caused by inductance value change when the non-resonant coil of the wireless charging transmitting end is prolonged and changed is effectively solved.
