Induction Heater Description:-
I used a simple push-pull oscillator circuit or the so-called ZVS driver.It is also often used in amateur structures of induction heaters.The scheme (circuit) is so popular that there is lots of Chinese production
The optimum power supply voltage is 12V, although worked from 3.5V. The power supply should be sufficient to trigger the FETs.
I used the N- channel IRFZ44. Gate resistors limit the gate current . By changing the parameters of these components the working frequency of the generator can be changed.As I have said before, the scheme often used for constructing simple induction heaters, although it is not an optimal due to the absence of the scheme for FETs regulation and good oscillator.
Large currents flow through the circuit, and the capacitor is also operated in hard conditions.Particularly, if the circuit is used as an induction heater, i.e. if the core is absent or it is not closed.Therefore, I advise you to use a battery of capacitors connected in parallel with a total capacity of 1 to 4.7 microfarads and voltage of 630 to 1600V. Optimally is 1000V. Practice shows that 400V, not enough.In the case of the capacitor bank, all should
have the same capacity and voltage. you can make a core with 7 to 10 turn with 1mm copper wire
