Kind of like the arc from a flyback transformer when you blow air across it, just like that, except the whole 4″ streamer looks that way. I have killed small flybacks in less than 6 seconds at 12 volts input. If it has to do with Tesla coils, post it here.

Flyback Transformer Driver – Electronics-Lab

They are deserving of my most heartfelt thanks. So far, staccato hasn’t helped sparklength much, but then again, we just got the thing working. SW1 is for the “high voltage ON” switch, it must be rated at or above 5 amps at any voltage.

The circuit is extremely stable and highly reliable. There is no point in using a full wave design as there are no corresponding pulses of opposite polarity.

In fact I built this circuit.

Flyback Transformer

Please don’t leave it plugged in. The high frequency used permits the use of a much smaller transformer. Aron’s driver is on a breadboard, mine is on a nice circuit board.

Coronafix Sun Apr 19 At some point, the circuit will get highly unstable Note that illegal explosives are not an acceptable topic of discussion.

Between the rod and the frame is an air gap, which increases the reluctance. It doesn’t work perfect yet but developments are being made I know how to fix it if it fries ; Safety This circuit has the capability of seriously shocking you. Once the voltage reaches such level as to allow the secondary current to flow, then the current in the secondary winding begins to flow in the form of a descending ramp.


The MAX is the reason for that. When some energy is always stored in the core and the current waveforms look trapezoidal rather than triangular flyack, then this is continuous mode CCM. Unfortuately, this is not a “clean” DC not suitable for integrated circuitsthe following circuit takes the ripple out of the waveform, and basically makes the power look perfect, more like what comes out of a 12V battery.

The users of this forum have made a total of posts.

When the switch is turned off, the current in the primary falls to zero. A convenient side effect of such a transformer is the considerable energy which is available in its magnetic circuit. This site uses Akismet to reduce spam. This is the place to do it.

In particular, very high voltages are easily obtained using relatively few turns of windings which, after rectificationcan provide the very high accelerating voltage for a CRT.
