A PCB coil can not practically have enough inductance for these lower frequencies, thus Niklas’ design employs a very high frequency indeed for a Tesla coil design, 2.6 MHz with both primary and ...

Unlike most Tesla coils, [Teodor]’s design ... frequency of the secondary is nearly identical to that of the primary. This creates a significant voltage boost, helping produce very high voltages ...

a Hall-effect element path to capture DC and low-frequency current information, and an inductive coil path that captures high-frequency current data. They’re combined to sense wide frequency ...
