Transformer with sinewave output and harmonics
« on: February 24, 2008, 20:37:26 pm »
Hi,

Another schematic for you guy's.
The main purpose is to create a sinewave with harmonics on the secondairy coil of the tranformer!
This will create more gass in your WFC.

This schematic uses a CD40106 as oscillator in stead of a 555 timer. Its more stable.
The 2 potmeters are used for setting frequency and gating.
Select a capacitor for your frequency range. I drawd 3 , but you can add as many as you like. Just use a rotaryswitch for selecting.

Output is into 2 FETS. When one gate is on, the other one is off.
You can use any FET you like. I use IRF240. Its pretty big and used in the audio industry.
Trafo is what you want. depending on your needed voltage and amps output.
If you want very high volts, you can add a capacitor of 0.1uF across the 2 outside poles (fet outputs) on the primairy side and tune into resonance!
