    My first ever tesla coil build

    I'll add to my blog a better description of how the traditional spark-gap tesla coil and slayer exciter circuit are different. There seems to be a lot of confusion on that point :) Thanks, Matt

    My first ever tesla coil build

    In a traditional tesla coil there is two oscillators the primary, and the secondary, which are both inductor/capacitor resonators In the slayer circuit. There is only the secondary LC resonator, the primary LC resonator is replaced by a transistor oscillator, which doesn't need tuning because it...

    My first ever tesla coil build

    In a traditional Tesla coil, yes, the primary needs to be tuned as the primary LC oscillator needs to resonate at the same frequency as the secondary. The slayer exciter tesla coil has no such capacitor and the primary isn't configured as a resonant/LC circuit, so there's nothing to tune...

    My first ever tesla coil build

    The slayer circuit tunes itself because it's locked/synced to the secondary. Low voltage on the secondary turns off the transistor. It also doesn't have a tuned primary circuit. So there's nothing about the primary to 'tune' as such. The LC circuit on the primary of a traditional tesla coil is...

    My first ever tesla coil build

    A choke is a pretty good idea; I'll probably try that if I ever revisit this circuit. The flyback is definitely not the only reason why this circuit tends to kill transistors though. They also spend a lot of time in a half-on state, so they dissipate a hell of a lot of a heat, The LED diode...

    My first ever tesla coil build

    I've been meaning to experiment with different primaries. The Slayer Exciter though doesn't need fine tuning the resonance of the primary as the transistor circuit automatically tunes itself to the resonance of the secondary

    My first ever tesla coil build

    I've now got a full write-up on a much more powerful tesla coil circuit. Thanks! https://siliconjunction.wordpress.com/2017/02/25/my-first-tesla-coil-mosfet-version/

    My first ever tesla coil build

    I believe my explanation isn't exactly correct. I don't fully understand how the tesla coil operates myself. The standing wave 'bouncing' off the top and bottom isn't entirely accurate. I believe capacitance between the secondary windings and also the top load and the secondary windings comes...

    My first ever tesla coil build

    With a Tesla coil you usually try to get a weak coupling between the primary and secondary. A Tesla coil is different than a regular transformer in that it's a resonant transformer. A standing wave goes up and down the secondary, bouncing off the top and bottom of the coil. The primary adds...

    My first ever tesla coil build

    I've documented information I've found in building my first ever Tesla coil: https://siliconjunction.wordpress.com/2017/02/20/my-first-tesla-coil-slayer-version/ I'd appreciate any comments on anything you think i could improve or I've done wrong. Thanks Matt.
