ZVS Induction Heater

Welcome to all Technology science lover in this web.
Today, we are making a ZVS Induction Heater based on IRFZ44N mosfet Transistor. The total cost of this system is 5$-6$. Induction heater coil makes powerful and solid state magnetic field these flow more electron in a second amd here makes a more friction mainly converter in the core of the coil.
The core is any metallic thing. This is very useful in metal melting, metal bending, fixing and much more. The circuit diagram is referring the IRF250 but i am used IRFZ44N not more difference in those transistor because IRF250 is best for ZVS flyback driver and IRFZ44N is best for Induction heater. The induction coil arrived from main voltage to Capacitor voltage and so use a 1200v capacitor may be 0.22uf to 0.63uf. Main voltage of this system. Some picture is declaring for this system.

The Circuit Diagram

When every metal is put inside this coil the metal temperature going out to 300 degree Celsius to 380 degree Celsius totally danger for hot. 

Know More For IRF250

Fifth Generation HEXFETs from International Rectifier utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET Power MOSFETs are well known for, provides the designer with an extremely efficient and reliable device for use in a wide variety of applications. The TO-247 package is preferred for commercial-industrial applications where higher power levels preclude the use of TO-220 devices. The TO-247 is similar but superior to the earlier TO-218 package because of its isolated mounting hole.


The MOSFETs used need a voltage rating about 4 times higher than the supply voltage and a on-resistance below 150 mΩ5 + 5 primary windings are suitable for voltages between 10 to 40 VDC, at higher voltages additional windings will be needed. Experiment with the number of windings to improve performance. Too few windings will result in excessive heating and too many will result in reduced power outputA MMC is made from 6 capacitors to avoid excessive heating in a single capacitor.This driver will push as much power as it can, so be sure to use flyback transformers that can handle the abuse if you want it to live.
