This project is really simple and surprisingly effective at heating metals using high frequency magnetic fields.
Diy induction heater circuit diagram.
Aug 28 2014 learn how to make a nice and fairly simple induction heater that can be used to heat treat tools and much more.
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 duty control of the pwm circuit is inverted compared to the output power of the heater.

Now you can watch my new video.
The schematic diagram of the induction heater with igbt s.
See the link below for the schematic.
Which means setting the duty to 100 will turn off the heating.
A simple alternative to this may be in the form of bc547 transistors connected instead of the diodes as shown in the following diagarm.
Commercially they are used for heat treating brazing soldering etc as well as to melt and forge iron steel and aluminum.
An induction heater consists of an electromagnet and an electronic oscillator that passes a high frequency alternating current through the electromagnet you will get full explanation about 12v induction heater circuit diagram below.
