![]() The machine, due to its intended purpose, did not provide big fat arcs – however I think it’s still impressive and worth mentioning. The result was a compact, short-circuit proof, high voltage “lab” supply with frequency control, some active cooling, audio modulation (singing arc, or a plasma speaker), two 5-15 kV high voltage outputs (AC and DC) to play with things such as plasma globes, small Jacob ladders, multipliers, and so on. So, let’s begin!īut to say the least, the first driver I have built with this topology had an AC flyback and an input power supply rated just 60 watts. Since these flybacks are normally sealed in epoxy and can withstand an output voltage of 50 to 75 kilovolts, why not use them in drivers such as this one… □ Moreover, the simplicity of this circuit also adds a possibility of some simple audio modulation of the arc. This single transistor flyback driver topology was created in response to achieve higher efficiency and higher output voltages from ordinary CRT television flybacks (diode split flybacks), for experiments such as x-rays or ionic lifters, without having to make any external HV multipliers. ![]()
