My Tesla Coils
Here are some of the Tesla Coils I built over time. It has been a long time since I built (or even powered one). But they’re still amazing.
PS: The dates are actually when the videos were sent, not when recorded. Although the difference shouldn’t be much between recording and uploading.
ZINC SSTC (Audio Modulated) [ August 27, 2012 ]
So this was my latest Tesla Coil built. It is a small SSTC driven by two IRFP250N, a GDT Driver made on protoboard ( yeah LOL ). It was designed to be “portable” so I could take anywhere to show people. It works with the same Audio Interrupter I designed for ZARC.
Driverless SSTC [ November 23, 2011 ]
That was a circuit I designed. It’s basically a half-wave rectified Driverless SSTC. There is a Current Transformer on the secondary that feed the energy directly to mosfet gates to switch it. I never optimized the circuit, but it works.
ZARC with FPGA MIDI interrupter and 220VAC Mains [ September, 16, 2011 ]
And a very nice explosion of my Variac:
That was basically the final setup of ZARC. A polyphonic FPGA Interrupter (4 channels) that drive the main controller in the bottom of the tesla coil. Current Limiter at 400A (never reached more than 320A, I detuned the coil a bit to keep the current limited). The coil is still here, and could be improved. But I have no space anymore :/
ZARC – New base with better tuning [ April, 6, 2011 ]
Now I remade the base of my ZARC DRSSTC and tuned a bit more. This is basically my final Setup for ZARC DRSSTC. 1kW input, 110V doubled mains ( about 320VDC in the bus). 300A peak in the fullbridge of IRG4PC50UD
Funny that this is probably my best Electrical Engineering project lol.
ZARC – First under-test DRSSTC [ March, 4, 2011 ]
So this was ZARC in actual final body without final tuning. The interrupter was the same shitty one as before, but now almost 70cm sparks and better stability.
Musical DRSSTC [ February, 26, 2011 ]
This was the first good working DRSSTC with audio modulation (I did other attempts before, but all of them resulted in explosion). Same ZARC prototype as before.
Mini DRSSTC [ February, 26, 2011 ]
Again my Mini DRSSTC.
Micro SSTC running at 1.5MHz [ February, 26, 2011 ]
A CW SSTC running at 1.5MHz with Fullbridge of IRF740 (yeah I know, IRF740 with 1.5MHz is crazy)
Medium SSTC 3 with Audio Modulation Interrupter [ February, 26, 2011 ]
Same secondary as all my Medium SSTC ( and my first DRSSTC). But different topload and audio modulation.
My First working DRSSTC
Primary Current Transformer feedback DRSSTC with a halfbridge of STGW30NC60WD IGBTs @ Doubled Retified 127Vac Mains, 300V at Main Bus.
Medium Half-CW SSTC [ February, 26, 2011 ]
Medium SSTC ( 30×10 cm secondary ) running with two IRFP260N at CW with half-wave rectifier supply (no filtering).
ZVS Spark Gap Tesla Coil (Flyback) [ February, 26, 2011 ]
A flyback run by a Mazzilli ZVS Driver with two IRFP250N @ 30VDC supply. 1nF 40kV Capacitor Bank
First Prototype for the ZARC DRSSTC (600W) [ February, 26, 2011 ]
This is actually my last DRSSTC, but in the prototype stage. It was generating almost 50cm of sparks. It was using now IRG4PC50U IGBTs with reverse Ultra-fast Diodes for damping the reverse peaks.
