A high-voltage supply transformer (T), to step the AC mains voltage up to a high enough voltage to jump the spark gap.The common spark-excited Tesla coil circuit, shown below, consists of these components: Although some oscillator-driven coils generate a continuous alternating current, most Tesla coils have a pulsed output the high voltage consists of a rapid string of pulses of radio frequency alternating current. The alternating current output is in the low radio frequency range, usually between 50 kHz and 1 MHz. ![]() Tesla coils can produce output voltages from 50 kilovolts to several million volts for large coils. More sophisticated designs use transistor or thyristor switches or vacuum tube electronic oscillators to drive the resonant transformer. Tesla's original circuits and most modern coils use a simple spark gap to excite oscillations in the tuned transformer. C2 is not an actual capacitor but represents the capacitance of the secondary windings L2, plus the capacitance to ground of the toroid electrode E.Ī Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. Tesla coils are used for entertainment at science museums and public events, and for special effects in movies and television. The high electric field causes the air around the high-voltage terminal to ionize and conduct electricity, allowing electricity to leak into the air in colorful corona discharges, brush discharges and streamer arcs. Operation Homemade Tesla coil in operation, showing brush discharges from the toroid. Originally, Tesla coils used fixed spark gaps or rotary spark gaps to provide intermittent excitation of the resonant circuit more recently, electronic devices are used to provide the switching action required. ![]() Today, their main usage is for entertainment and educational displays, although small coils are still used as leak detectors for high-vacuum systems. Tesla coil circuits were used commercially in spark-gap radio transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray devices. Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high-frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits. It is used to produce high- voltage, low- current, high- frequency alternating-current electricity.
