Problems solved by technology

[0004] In order to solve the problem that the traditional string-string structure has low voltage gain and cannot meet the system output voltage requirements under the condition of long-distance weak coupling, the present invention proposes a topology circuit for linearly increasing the voltage gain of long-distance wireless power transmission. Compared with the string-string structure, in the case of the same transmission distance, the voltage gain of the system can be linearly increased only by adjusting the ratio of the compensation capacitor to meet the actual system requirements
