This is a low-power induction metal heater that can heat red-hot thin metal.The generator is made on an IRF540Z transistor.From this generator, you can make a fire generator
The transistor is mounted on the radiator.A variable capacitor adjusts the maximum power in the coil L1.With a variable resistor, it is necessary to set the optimal voltage at the gate.
The coil L1 has an inner diameter of 20mm and contains 6 turns of 1.5mm wire
The L2 coil has an inner diameter of 4mm and contains 14 turns of 1.5mm wire
Capacitor C1 at a high voltage of 4-5 kV,it will heat up.
Capacitor C3 consists of three capacitors with a capacity of 470pF each and also at a high voltage of about 2 kV.
A variable capacitor with a capacity of approximately 15-300…400pF
Customization.With a variable resistor and a variable capacitor, set the consumption current to about 2A at a supply voltage of 9 Volts.Take a fluorescent lamp and bring the bulb to the coil L1, the lamp should shine brightly.When changing the capacity of an alternating capacitor, the current consumption will change.Do not allow current above 3 amperes when idling
Take the blade.Do not take it with your hands, take a non-conductive material.The blade will be red-hot in just a few seconds.At the same time, the current consumption will increase
