For the inductor is this a suitable one http: Currently i have 3 of these mosfet but i will buy more soon. After that we got around 10 minutes of runtime. Note that the gate bias voltage must be lower than the drain supply voltage to ensure that the coupling diodes are reverse biased when the drain is high. Thought maybe pll but why not skip and go drsstc! I would be happy to assist you any further if needed. Good high-capacitance MKS capacitors can be pricey if purchased new e.

ZVS Flyback Driver G1 |

It runs 48V DC 20A when under full power. Hey hanghuutri Have you tried to calculate the different resonant frequencies you flyyback with different work coils?

In the end there might not be a big difference in the output from going for high voltage as you have to take your precautions to insure its safety. It can properly run down to some kHz, not that I have tested it, but its an assumption based on time needed to switch state. If you keep tank voltage below V then youre good to go. This site uses cookies. Interconnection traces on a circuit board should be as wide and as short as possible. When I winding the primary coil in tube-shaped, the induction heating is ok.


Are my FETs dying due to the inherent instability of this driver, or do you think they died because the secondary arced to the primary through the core?

In some designs a single ferrite core with two windings is used transfprmer a common-mode filter configuration. It can however be overdriven a little, to some 24V maybe.

November Learn how and when to remove this template message. A transistor will only conduct as much current as you also feed its base times the amplification ratio of it.

What good is flybacck car that electrocutes people, which pisses them off and they throw a brick through the wind shield? The flyback did arc a little bit to the core on the inside.

Once an arc appears, after bringing the secondary wires close enough, frequencies shoot up to over kHz in 2 of them and over kHz in the other perhaps due to feedback from the arc to my frequency meter? January 10, at I build this circuit almost a year ago on a vero board, but it kept blowing the thin traces due to high currents flowing.

Frequency meter indicates 22kHz for 2 of my units, over 45kHz for another — all without arc. Hello Mads, Thanks for all of your awesome work. Which means, possibly polypropilene, or anything similar.


That kept the rise time decently low. I am wanting to create a variable ozone generator circuit, so looks like ZVS is not a good way to go about it.

As previously noted, a better design is to use a separate gate power supply fpyback off the main power supply, as shown in Schematic 2.

The e lamination stacks on each other and so does the I lamination, then they are welded together.

Basic ZVS Driver Circuit

I will keep looking around to see what I can find, Cheers! Thanks Mads, That is very true about Facebook, and I October 3, at Color television sets also have to use a regulator to control the transormer voltage.

Oh God, sorry everybody, I find out that I picked up resistors with wrong value. May 12, at Waveform for zv Single Turn Secondary. The ZVS driver is by nature not very stable, it will suddenly explode from hardswitching large currents or overvoltage.
