Mosfet induction heater

  • Published on Jan 7, 2019
  • Hello friends, today in this video i have shown how to make an induction heater using less components.
    Parts list:-
    2 × z44 mosfet
    2 × 330ohm resistor
    2 × 10K resistor
    2 × Fr107 diode (you can get from old CFL driver circuit)
    1 × 1uf capacitor
    Heatsink for the MOSFETs
    And ofcourse a 12V power source

    *When you put metal inside the induction coil, How much current does it draw? Why did you not add a toroidal transformer with positive end?*
    Inform me, because I want to make it from a long time but I do not have any lab bench power supply.

    You talk about Fr107 diode from CFL driver circuit , why i only find a 13003 mosfet in it ??

    • Antoni Maciek
      Antoni Maciek 6 months ago

      @Kami Star It is a bipolar transistor npn! Not diode...there are FR107 or similar diodes in CFL in DO-41 housings, usually 2 to 3 pieces, do not confuse with 1N4007 rectifier bridge, recommended diode UF4007, FR207, 1N4937.1N4937RLG, BYV27-200, HER208, MUR 460,UF5404,....

    How a electromagnetic field produces heat?

    • Neil Paul
      Neil Paul 8 months ago +1

      @Steeve Smith The coil produces a magnetic field comprising multiple magnetic field lines which alternate in polarity at the same frequency as the oscillator. The physical construction of the coil does not lend itself to creating an external force. Also you would need either a second magnetic field or a ferrous object with which the magnetic field could interact. This is a completely different application of electromagnetism to that of solenoids, most electric motors, maglev etc.

    • Chris Barth
      Chris Barth 8 months ago +1

      @Steeve SmithNo, the switching happens too fast to create any perceptible magnetic effects.

    • Steeve Smith
      Steeve Smith 8 months ago

      Neil Paul thanks 🙏 so the heat comes from eddy currents right, but is there any force that pushes the ferrous to the direction of the coil core? Like the coil train.

    • Neil Paul
      Neil Paul 8 months ago +2

      The circuitry forms an oscillator causing an Alternating Current (AC) to flow in the low resistance (copper wired) 'output' coil. The AC current causes an alternating magnetic field to be generated around (but perpendicular to the axis of the individual coil wires) the coil. The magnetic field is at maximum density inside the coil but sparse around the outside of the coil. As the magnetic flux lines expand and contract though a ferrous (magnetic) material an electric current (commonly known as eddy currents) is induced in the 'metal core' at right angles to the magnetic field. The current x resistance of the ferrous material results in power in the form of heat energy. In power transformers these heat losses are minimised by the use of insulated steel laminated formers. Metallic granules imbedded in insulative resin is also employed as formers for the same reason. The 'former' concentrates the magnetic field into a known volume to improve the efficiency of inductors and transformers. I hope this explanation assists your understanding of why a ferrous object heats up when it is inside the coil but an item made of a 'non-magnetizable' material stays cool.

    I need to supper heat a 4in copper pipe. With a bigger coil would this work?

    • Chris Barth
      Chris Barth 8 months ago

      No way! You need some serious current switched at high frequencies to do what you want even for a ferrous metal like a 4" steel pipe, copper may not even work since its non ferrous. The induction coil almost always involves a 3/8" or larger copper tube with water circulating for cooling. Not really a DIY project unless skilled and motivated.

    Heat sinks are a must for the mosfets, they will get hot. Doesn't have to be exactly like what is shown, anything of similar size made of aluminum or copper with a flat surface should work, more mass is better. An old computer CPU heatsink would work great. Thermal paste under the mosfets will help tremendously. Hell, even toothpaste (yes, toothpaste) will be better than nothing.

    how to reduce the power? i tested with my power supply that i build and at 5v it seems to drain alot of current. no heating of course but if i increase to 12v for sure my supply will burn, my supply can carry 8A at 14v.

    • Hudsonkem Marinho

      @Chris Barth good to know thx, i will try with more turns.

    • Chris Barth
      Chris Barth 8 months ago

      IMO a 14V 8A power supply should be fine. Maybe try to heat small parts at first? More turns on the coil should reduce current as well if I'm not mistaken.

    Good... But wait! You didn't told us that the 12V power source should be able to handle 10A+ of current. And also the capacitor would quickly heat up until it burns out failing all the circuit. Nice try.

      @ГранЬ АрС схема на 52 секунде. Резисторы по 330 ом - 2 шт. резисторы по10 килоом - 2 шт. транзисторы IRFZ-44 - можно аналогичные на ток 40-60 ампер и напряжением от 100 вольт и выше. конденсатор, что синий, на 1 микрофарад и напряжением желательно от 1000 вольт и выше. Провод на катушку диаметром 1.5-2.0 мм. Всё это применительно для данного случая. Можно поднять мощность, увеличив ёмкость конденсатора, следовательно и диаметр провода катушки. Питать от компьютерного блока думаю можно.

      Not fake. Try a 12V PC PS. Almost every house has an old unused computer with one more than capable of driving this circuit. Need to do a slight mod to get the PS to output 12V without a motherboard being connected.

      #12 bare copper wire wrapped about 10x around a 1" pipe/dowel. Looks like he's just using a long loop in the middle as a heat sink to help avoid coil overheating. It doesn't affect it's operation, only the coils themselves are the working parts
