The invention discloses a wireless power transmission system based on a low-stress inverter. The wireless power transmission system comprises the low-stress inverter, a transmitting part, a receivingpart and load, wherein the low-stress inverter is taken as a high-frequency power source of the wireless power transmission system; the transmitting part comprises a transmitting coil and a first capacitor connected with the transmitting coil; and the receiving part comprises a receiving coil and a second capacitor connected with the receiving coil and transmits received electric energy to the load. The wireless power transmission system disclosed by the invention has the characteristics that firstly, a switching tube of the inverter has lower voltage stress; secondly, the inverter has higherelectric energy transmission efficiency; and thirdly, the working frequency of the system can reach above MHz. In the practical application, the corresponding power grade and frequency can be designedas required. 本发明公开了种基于低应力逆
