                   Tesla coil circuit diagram

First, the circuit principle of Tesla coil is: The transformer is used to boost the ordinary voltage, and then charge the resonant capacitor of the primary LC loop to the discharge threshold, the spark gap is discharged and the primary LC loop resonates in series to provide the secondary coil with high enough excitation power, followed by the frequency equal to the secondary LC loop, so that the primary coil and the inductor and the distributed capacitor resonate in series. And then you see the arc of the discharge.

Second, 12V Tesla product introduction:

1. This product has large power, high frequency, should not be heat dissipation, can not work for a long time, if you need to work for a long time, please add another fan (outer diameter greater than 5CM, speed more than 5000) heat dissipation to ensure that the working temperature of the transistor is below 50℃, the transistor is too hot to cause abnormal arc or even burn out.

2. About the power supply: 12V Tesla working voltage DC 5~13V, need to configure the discharge current 2A, power more than 30W, output ripple less than 100mV DC source.

3. When working, it is necessary to straighten the wire at the top of the coil, and ensure that the product and other objects, including the human body, especially metal objects, are kept above 10 cm to avoid circuit interference and safety accidents.

4.Artificial arc extraction method: under a certain voltage input state, use a screwdriver or driver near the top of the coil to lead out the arc, the discharge end will be oxidized and black for a long time, the discharge effect becomes worse, at this time you can cut off the blackened part, and then re-tin to achieve the perfect arc pulling state.
