Analysis of the Tesla transformer operation at the first half-wave of the output voltage taking into account ohmic losses

The speed and efficiency of the Tesla transformer at the first half-wave of the output voltage are studied as a function of the Q factors of the circuits and their coupling factor. Calculated results and experimental data are considered. It is shown that for given Q factors, there is an optimal value of the coupling factor providing the highest efficiency, which can be calculated and for which designers should work.
