Tesla Transformer and its Response with Square Wave and Sinusoidal Excitations

摘要

This paper analyses the output of Tesla transformer from input defined as square wave and sine wave and its transfer function obtained from its equivalent circuit. The transfer function presented is analyzed in terms of the time, and the output is obtained when applying an input defined as a step and a sine function. When using square wave, the high gain obtained is proved that is due to a sum of responses obtained through positive and negative step that forms the square wave. However, the gain obtained when the excitation is a sine wave is higher than square wave excitation. Thus, in this paper is shown that the Tesla transformer works with sinusoidal excitation too, and present higher gain than square wave excitation, both higher than expected in classical transformer theory (turns ratio). All analysis presented were based in simulating operation using MATLAB comparing with experimental data.
