Also, the coil is running with a separate secondary from the one I will be using it’s a 12″ x 2. Driving the transistors is a simple exercise for a power engineer, but more challenging for a hobbyist. After the varnish on my actual secondary coil had dried, it was time to test it! The second is the high mains-voltage inverter itself, which drives the primary coil. At this power, the coil is quite loud indeed and the sound resonates in the room and induces significant RF in metal objects in the room, which can be felt in terms of RF burns when touched Next, we need to know what the resonant frequency is.

They are very nice as switches due to their high off-resistance, low on-resistance and only require a small gate current to turn-on basically solid state tesla coil up a small capacitor in the gate to turn it on. I have also used an ATTiny85 micro-processor to produce the interrupter signals instead of a standard timer.

The coil is working! Email required Solid state tesla coil never made public. These sloid diodes are used to reduce flyback, which is the sudden voltage spike seen across an inductive load when its supply voltage is suddenly reduced or removed.

It came in a nice black box with an IEC power input jack, ground connections and a nice big fan all integrated. This allows the user to control the duty cycle of the SSTC.

SSTC III. – Solid State Tesla Coil with 50Hz / 100Hz / DC operation

The photo twsla shows the new primary supports! The board was inserted into the case held in place via two screwsand plugged in. The coil then runs very happily off secondary base current and is what I use in my final design. This is done by keeping any leads or wires physically as close together as possible. With the interrupter, we can now create a variety of modes to drive the SSTC!


Solid state tesla coil SSTC IV. with IGBT

Power consumption is approximately – Watts. IGBTs are almost cold. This photo records this moment! Fill in your details below or click an icon to log in: If this page was helpful, feel free to share it with others too! This circuit comes in solid state tesla coil common forms – a solid state tesla coil bridge or a full bridge.

The coil sprung into life easily, but it was clear that when I raised the voltage over 80V, I started to get skips i. The length of the secondary should be about a quarter wavelength of your design Tesla coil frequency.

The right photo shows the output of my completed GDT. And as a reward of reading till here, here’s the schematic for the entire Sate 2 for your reference! Solid state tesla coil the final piece of the puzzle is the interrupter code. One important thing to note in the physical design of the bridge is to minimize stray inductance.

DIY Solid State Tesla Coil

One important note is that it is important to add a DC-blocking capacitor in series with the primary coil across the inverter output. To solve [1], I added a second layer of insulation using an acrylic form. Here, SSTC 2 is making around 8″ sparks solid state tesla coil us ocil. Additional things to take note of include adding subber capacitors to the IGBTs film capacitors mounted physically close to the IGBT – these are meant to soak up transient high voltage spikes and twsla are usually rated around 1kV and 1 to 6uF – I have omitted them in tes,a design because of the low-inductance layout of my bridge.


Additionally, due to resonance, the primary voltage also increases from line voltage up to the several kV.

The platform also allows intake for the big mm fan which provides cooling for the whole coil. I was interested what happens in this circuit srate than creating one- the video does not explain anything about the circuit and how it works solid state tesla coil circuitit only shows how it works the SSTC The current also increases up to several hundred to thousands Amperes.

Which I recommend on the instructable. The output of the interrupter is usually some kind of logic signal usually 0V for 0 and 5V for 1and this can be fed directly into our drive chip’s enable pin.

so,id A common method of use simply calls for a vertical wire being places a few centimeters from the coil, around 15cm in length. Results and Media 5.
