| How a modern Tesla Coil works
Gregory explains how a modern DRSSTC Tesla Coil works.
The working principle is explained from the Tesla Coil end-result - the creation of big sparks - going backwards to the power electronics stages and how they operate.
A modern DRSSTC Tesla Coil utilizes a power electronics inverter, feeding a double resonant circuit that converts the low impedance power, creating high voltages sufficient for breaking the dielectric limits of the surrounding air.
The power inverter runs bursts of 1500A over the primary-side resonant tank. Energy is transferred to the secondary-side by inductive coupling. The overall circuit of the Tesla Coil is modeled as a band-pass filter that matches the voltage and current profiles between primary and secondary.
A PFC of the boost topology feeds the inverter DC bust, taking power directly from the 220VAC mains. The quad-phase topology is explained and why the discontinuous mode of operation was chosen.
