Resonance on Coils Excited by Square Waves: Explaining Tesla Transformer

In this paper, effects of induced electromotive force (EMF) on coils excited by square waves are shown, as well as how these influence resonance phenomena. The work was based on experimental results, using planar coils and inner ring coils. A priori, the resonance is presented as effects of parasitic capacitances on coils, which through inclusion of external capacitances, is established that the phenomenon of high voltage on output is the sum of responses of the induced EMF added with response to step voltage on rise and fall of the square wave. Consequently, the found results explicate the phenomenon of high energy (or high voltage) in the output of Tesla transformer.
