    I've worked with induction heating since 1987. Really nice project. The heating power is quite impressive and has the potential for more. The magnetic flux decreases by the square of the distance to the work. With a tight coil you would couple much better to the output. Of course, the current would still be limited by the power supply and resonant circuit. Commercial coils are filled with sand when winding so that they don't collapse, especially with small diameter coils. Afterward, they are sprayed with Glyptol to provide insulation. Many times they are also lined with a refractory tube, and cast in refractory cement. If not potted, larger bare coils have some type of insulating structural spacers attached parallel to the axis of the coil on the outside to prevent the coil from jumping when energized. Invariably the output coils are water-cooled in all sizes of induction heaters. It's true, you don't want to get bit. Radiofrequency is more than a shock. I once contacted the 650-volt dc buss on a 300KW machine in Yonkers. It knocked me back six feet against a piece of equipment. I was lucky. The most dangerous job I've ever had.

    I used to build RF Induction heaters back in the 80's. We used big tubes back then by Siemens. All the components were hand made, The coils were water cooled, 1.2 KW were the small ones and had some monster ones that were in cabinets equal to server cabinets. Spaulding had used a couple of ours when they had defective grips on their golf clubs and needed to remove them. The machines had fittings on them so different coils could be used to match the projects and the machine had variable current controls and timers.

    Best induction heater build I've ever seen. Looks great and I loved your meticulous attention to detail. Very fine work indeed sir. One question though...On the Gerber files, would it be an issue to increase the thickness of the traces, in particular the fat ones you have to tin and add more copper to the traces? I was thinking about building this version, but either ordering the PCB with the thickest traces I could select or adding a copper busbar or long copper braid in addition to the tinning on the fat traces. I don't know if that would make much of a difference, but I like the idea of improving the current-carrying potential.
    Also, if I may offer a suggestion. I had an induction heater similar to yours a few years back and I used a water pump, silicone tubing, a water reservoir, and a CPU AIO radiator from a retired CPU cooler and attached the tubing to both ends of the copper coil creating a water-cooled induction coil which worked really well. I bet that would help your desoldering problem and avoid overheating the PCB.

  • @robertbarnett6879
    @robertbarnett6879 3 ปีที่แล้ว +4

    I know its typical for ppl to argue about soldering but when solging the copper tabs to the coil it helps to heat where u want the solder to go so it can work its way to thier with capilary action.

  • @DoctorStalker1
    @DoctorStalker1 3 ปีที่แล้ว +22

    I suggest a slight design change to improve things: connect one end of the coil to the capacitor farthest from the coil. This will better average current to each capacitor.
    The capacitor nearest (#1) the coil is handling more than its fair share of current, which is why the solder melted there.
    The capacitor furthest (#10) from the coil is handling the least current.
    Like you said, there is hundreds of amps flowing through the traces and will preferentially flow where there is lower resistance. It may not matter at low power but there might be some fireworks at high power.
    I built one of these using the center-tap variation. It uses a second fixed 12v supply on the driver side to keep the mosfet gates happy.
    Awesome project. Thanks.

    One suggestion:
    For the two main high-frequency busses: Instead of filling them with solder, skin some ROMEX (12 or 14AWG solid) make them straight and put two of these next to the capacitor leads on each bus and cover everything with solder.
    Or better yet, if you can machine two rectangular copper busses with holes for capacitors, do it.
    For the caps: Search Digi-Key for film capacitors and "high pulse dv/dt" capacitors.
    These capacitors will carry huge AC currents and their ESR must be as low as possible.
    ....And NO you may NOT replace two paralled capacitors with one of double capacitance !!!

      Could you not simply increase the thickness (4oz) and area of the busses? iirc he said 30Amps should be able to be carried by a thick enough trace, although adding 10ga or 12ga wire should also work with the lack of mechanical robustness, and additional build work.

      You could also just make the traces wider. There's tons of unused board space there, and really no reason you couldn't make those traces 2 to 3 times the size they currently are..
      You could also put the traces on both sides of the board (with a good number of vias connecting them along the way), basically doubling the amount of copper that way as well.

    Nice layout but ideally the mosfet should not heat up much and the mass majority of the currant should go within the coil and the capacitor bank. I have made quite a few ZVS and basically you can optimize it by 1. change gate charge resistance until mosfet stays cool, and 2. add capacitors until the frequency reaches close to audible range. I would increase the coil count to maybe 10 turns for 48v input and double the capacitor bank. If the mosfets are too warm, upgrade low R-DS mosfets and or decrease gate drive resistance.

      That all depends on whether you're dealing with a ferrous or a non-ferrous metal. The end result of thermal cycling is a desired crystal structure in the metal. If you want hard copper either work the metal or toss it into a 350F oven for an hour and turn off the oven with the metal inside. If you want soft copper heat it the same way an toss it into a bucket of cold water.

      Quenching in water has little effect on the final product as the high temperature is what allows the crystals to reform, however quenching it is just faster and can make the outside look nicer. Iron can be work-hardened as well and quenching will have little effect on the heated iron just as copper. Steel WILL harden as it is the rearrangement of the carbon atoms that occurs at higher temperatures that give steel it's high hardness, which obviously if cooled fast enough (tempering), won't have time to go back to their original places, leaving the material in a highly stressed and brittle state, which is essentially what makes a material hard

    • @mrkiky
      @mrkiky 3 ปีที่แล้ว +5

      ​@@Jakob6174 "if cooled fast enough (tempering)" - uh no, that's the hardening/quenching you're thinking about. Tempering is reducing the stress in the material which, when it comes to steel, is achieved by heating it up to a low , non-glowing heat and maintaining it there for a while giving the carbon atoms enough time and energy to get into a "more comfortable" position, but still kinda stuck in the iron atom lattice. On a macro level this gets us a compromise between hardness and toughness which is desirable for most applications like knives, tools and springs.
      I'll add this as well: there aren't any other common alloys that can be hardened through heat treatment (maybe some aluminium alloys), but nearly all of them can be work hardened, as that is just a function of the crystal grains elongating while you're deforming the metal until they have nowhere else to move. Moving it beyond that point will cause a break, but the force required to break it is usually much higher than what it previously took to bend it, hence the hardening. Heating it up after work hardening gives it a change to recrystalize so it can be deformed further without breaking, which is also why forging works.

    I think if you make the connection of the coil in the center of the PCB you reduce the current running in the traces. At the end of the trace you have the max current running, in the center it comes from left and right and therefore the maximum current in particular part of the trace is less.
