A Tesla-coil driver published as an academic paper, in IEEE Access (2023), by Mohammad A. Obeidat, Mohammad Nehad, Khaled A. Mahafzah and Ayman M. Mansour. The authors are from Tafilah Technical University, Al-Ahliyya Amman University and the Arab Open University in Jordan, plus Kuwait's Ministry of Education. The design builds up from the basic self-oscillating "slayer exciter" concept to a full H-bridge of four IRGP50B60PD1 IGBTs through IR2184 drivers, because "a half bridge clips out part of the voltage" at a given bus. One 555 timer generates the switching PWM and a second reads an antenna feedback signal. An Arduino Nano protects the IGBT drivers' shutdown pins against overcurrent and also plays back music. The paper states its limits. University lab safety rules capped testing at a 15 V DC input, so the abstract's figure of "15 kV, 200 kHz" is the design target, not a demonstrated spark. The board photos and the oscilloscope capture in the paper show the bridge switching correctly at that reduced bench voltage, nothing more.
