How does Induction Heating Work? || DIY Induction Heater Circuit

[@lptf5441]

Wow. That hand drawn circuit diagram is an incredibly beautiful thing. A piece of art. Congratulations!

[@greatscottlab]

Thanks ;-)

[@gertebert]

I learned to draw electronic circuits when there where no computers. I still draw mostly by hand. Drawing a circuit by hand gives you a better understanding of it. I encourage my children to write everything down. It's also very good for developing eye hand coordination.

[@barneylinet6602]

I built this circuit and would like to share some details that will help you . 1) Select polypropylene capacitors for lowest loss. It is bettter to use many smaller capacitors in parallel rather than a few bigger ones. 2) The circulating current in the tank circuit is very high; it is multiplied by the Q factor. Q factor is determined by tank losses. The circulating current is roughly equal to the measured circuit current draw multiplied by the Q. For example if the current draw is 5 A., and the tank Q is 50, the circulating current could be 250 amps. This is why the coil and the resonating capacitor gets so hot so quickly. By using many smaller capacitors in parallel you distribute this current so that no one capacitor will be subject to huge currents. 3) The voltage across the capacitor is roughly 2 pi times the supply voltage. Select capacitors with a voltage rating about 10 times the supply voltage. 4) Two critical ratings of the mosfets are: 1) the drain-source breakdown voltage. Each mosfet will be subject to a voltage of roughly pi times the supply voltage. The mosfets should have a voltage rating of at least 4 times the supply voltage. 2) Drain source current rating which should be calculated from the desired wattage of your circuit. In addition, the drain-source resistance should be a low as possible in order to minimize the head dissipated by the mosfets, and also to maximize the potential power available from a given supply voltage. Along with zener diodes to protect the gate of mosfet, it is recommended to place a small resistor (10 ohms is good) in series with the gate to damp out ringing which can subject the gates to excessive voltage. The gate of a mosfet is quite fragile, and should not be subject to greater than about 20 volts. 12 or fifteen volt zener diodes are recommended...... I hope that this helps experimenters with this useful circuit, and thanks to GreatScott for the excellent video presentation.

May I have circuit diagram?

[@shawalkassim800]

This is a great piece of information. Adding capacitors in parallel might help reduce heat/load on the capacitors itself. How could one reduce the heat of the coil without a fan, or pumping water through it? I have tried to mess around with the windings but is not effective in keeping the coil cool. Your help would be appreciated. Someone has suggested that a thicker copper wire should decrease the temperature of the coil.

Soldering also releases toxic fumes, that's why you buy a fume extractor, or solder near an open window with a fan.

In addition to the differences in resistance and magnetic susceptibility, different material also have different specific heat values. Aluminum, for example, has a much higher specific heat than iron or copper, steel, titanium and is about 7X that of Tungsten. So, it takes more energy/heat to raise a gram of Aluminim than for many other metals.

Agreed, there's alot a baloney when it comes to Mazzilli's so called simili "ZVS" topology applied to IH drivers - which typical lemming mystifiers are now satisfied to refer to as a magical "DNA" (...) despite the simple fact that removal of a flux concentration core in Mazzilli's Flyback Transformer can't reasonably be expected to work just the same as when he got photographed besides his Tesla Coil work, in 2008 ~ 2009... So, over a full decade has passed and yet today's fanboy tactics are being used to manipulate vulnerable people using half-lies and plain omissions. All of this just to revalorize obsolete PCBoards with ZERO protection, in an attempt to deny/ignore true technological advance in favour of getting delusional over IH Drivers supposed to cost less than a month's worth of pizza delivery i guess! Ah, and of course you never get to be shown any realistic Gate Waveform signals, much less in relation to their resulting output, as if the Mazzilli topology never inspired serious papers in superior institutions of knowledge before, for example: docplayer.net/26964431-High-voltage-resonant-self-tracking-current-fed-converter-a-thesis-presented-to-the-faculty-of-california-polytechnic-state-university.html High voltage resonant self-tracking current-fed converter (2010-Mar) p52/152 - Mazzilli Converter Topology Here we must forget about frequency vs alloy optimization, never heard of semiconductor junction recovery charges, nor parasitic resonances and so on!! As if electronic design has become just another excuse to justify the one other hobby that gathers the followers around some "social" love-to-hate activity instead - totally unable to dialog via relevant arguments, not to mention i got quite successful on Reddit illustrating such mediocrity in all its virtual glory... Much like the rationale behind half of USA still standing behind Trump even today, e.g. throwing a dice would easily beat such type of "science" that they claim to "work" (until it fails, then a deafening silence covers their few voids), while in fact nothing is ever done to prevent a catastrophic forbiden condition as "Shoot-Through" in the 1st place: imagine, these days an electronic breaker is supposed to take over but only after the short-circuit has started - and we're talking about very serious current being involved nonetheless.

is the mug made of metal? Induction heating only works on metals, not ceramic. Though I agree, I don't like the hot knife videos. They are absolutely boring.

[@rdxdt]

Jonathan Kayne yes it is, i guess its aluminum, but im not sure, my plan is a coffee warmer.

[@stevenkutschat]

You could make it just like he did but you'd have to make the coil larger than the mug so it'll fit. Plu you'd have to remember that the coil is heating the MUG which is in turn heating the liquid, so be careful and don't burn yourself.

[@rdxdt]

steven kutschat but still the same winding count? because the diameter of the coil will be greater than the shown on video.

[@JonathanKayne]

I don't know if I can help as far as the math goes, but I have about 3 industrial induction heaters that we use for drop forging. the coils are really large and it seems that inductance of the coil (AKA the diameter) has no effect on it. however, the coils are made of a copper tube so that water can flow through them to keep it cool. therefore, I would recommend you use a thicker gauge wire to let the resistance of the heating coil.

[@palmettokid54]

Simply use a cheap 40watt soldering pencil and a box cutter blade. Use the screw that holds the soldering tip, remove the tip and attach the box cutter blade through the hole in it to the outside of the heating coil, that secures the tip. So instead of a soldering tip you have a razor blade that is constantly heated by the solder pencils inductor. You don't need to keep heating it up; it stays hot. Cheap soldering pencil (40watt) stand, flux, and a small rol of 60/40 solder at Walmart = $9.99 and a pack of 10 razor cutters = $3.49. ⚡⚡ I use my variable solder station with a small coil of wire clamped in place of the tip, on my heat mat to keep my coffee hot.

You won't find it here, the fanboys are doing everything they can to preserve such odd "hobby" forever.

Actually there's no good reason to rely on 2008 technology which the "DNA" mystifiers now claim has self-protection built-in - which of course is a far stretch of reality... IMO the base line is to keep exploiting obsolete PCBoards previously populated for a Flyback Transformer feeding a Tesla Coil, e.g. with no insert/removal of the workload supported. Etc., etc. But that bubble won't resist further examination forever i hope. In any case it's no hint of genius to let the power stage enter a forbiden catastrophic failure state just because some guy has a nice moustache or a pleasant exotic accent, whatever. By chance major semiconductor designers/manufacturers now offer much more beneficial (to final consumer) cost/feature alternatives.
