The schematic diagram of the induction heater with igbt s.
In the above induction heater circuit diagram we can see the mosfets gates consisting of fast recovery diodes which might be difficult to obtain in some parts of the country.
The concept of the proposed simple induction heater circuit is straightforward.
A simple alternative to this may be in the form of bc547 transistors connected instead of the diodes as shown in the following diagarm.
The coil generates high frequency magnetic flux and then metal things in the the coil produces eddy currents which can be found warming it.
This diagram shows the addition of 2 diodes to the circuit so that it can be linked to one of our pwm control circuits for adjusting the power of the induction heater.
The duty control of the pwm circuit is inverted compared to the output power of the heater.
This circuit uses an arduino microprocessor up to follow the phase difference between the inverter voltage and the tank capacitor.
More ideas for you.
I want to ask you if the project will operate if i powred the circuit with a 12v baytery instead of ac and.

A magnetic field of high frequency is produced by the coil present in the induction heater and thus in turn eddy currents are induced over the metal magnetic object which is present in the middle of the coil and heats it.
The induction heater is built from a custom zero voltage switching zvs driver and powered by a small 48v 1000w power supply.
Using this phase it calculates the the correct frequency using a c algorithm.
While this makes for an exceptionally small induction heater it s.
