The invention discloses a high-voltage sine wave generating circuit which comprises a digital control module and more than two sine wave generating modules. The sine wave generation module comprises a sine wave generation assembly which is connected with a voltage input end and is used for generating pulses and generating sine waves by using the generated pulses; the output isolation assembly is connected with the output end of the sine wave generation assembly and used for voltage isolation and sine wave output; the digital control module controls the frequency of the pulse generated by the sine wave generation assembly so as to further control the frequency of the sine wave generated by the sine wave generation assembly. The output isolation assemblies of the more than two sine wave generation modules are connected in series to superpose generated sine waves, and high-voltage sine waves are obtained. The sine wave is generated under the low input voltage, the frequency and the amplitude of the sine wave are
