Tesla coils, invented by Nikola Tesla in 1891, are an electrical resonant transformer able to produce high-voltage, lowcurrent, high-frequency ac electricity. Telsa coil circuits have been used in many applications including electrical lightning experiments, x-ray generation and wireless power transmission, but nowadays tend to be used for educational and entertainment purposes. With the advances in power semiconductor devices, a new breed of solid state tesla coils (SSTC) have been developed which enables far greater control over switching of the resonant circuit allowing the arc to be modulated with audio. Led by Dr Andrew Lapthorn, UC’s ECE department has had several undergraduate students working on SSTCs over a number of years producing multiple coils. This talk will highlight some of the things the students have been up to and where to for the future.
