According to the primary and secondary loop resonance theory of Tesla transformer, the output characteristics of nonideal Tesla transformer under different coupling coefficients are studied. The MATLAB software was used to calculate the mutual inductance of the primary and secondary coils of different physical structures. The optimal primary and secondary coil structure and capacitance and inductance parameters corresponding to the high frequency AC voltage output with frequency of 300 kHz and amplitude of 255.9 kV were obtained. Then the model was simulated and verified by the Simulink module. Based on this, the physical prototype of the Tesla transformer was built. The output voltage of the frequency of 298.7 kHz and the amplitude of 241.1 kV is obtained by measurement, and the energy transfer efficiency was about 27.1%. The output voltage amplitude of the physical prototype deviates from the simulation value by 6.3%, which basically meets the design requirements. The Tesla transformer designed in this paper has certain application value for high voltage test, insulator string and other insulating materials in the performance detection under high frequency and high pressure environment.
