hey did you ever build this? was trying to see if there was any updated but couldnt find any. am also interested in a usb ihHi everyone,
I'm currently planning an IH build powered from USB-PD. I ordered most of the parts I will need, but I wondered if you could provide me with insights if anyone did something similar.
I might try the half-pint circuit, but I'm not sure if the mini-zvs I bought is compatible.
- Power : USB-C Power Delivery. Since it can do 100W, it might work, of course, depending on the power source.
- StepDown 12V : 24V to 12V 10A
I was also wondering if it's possible to separate the coil from the zvs board.
I have just realized that I don't have a glass tube.
it is similar to the first video i posted, which is a tutorial.I would think that you could wire (2) 18650's to a half pint, add some heat shrink, and have a similar sized portable IH.
Thanks Tommy! i didnt try this kind of circuit yet, no time right now, i just asked on the video comments because of 2s (and i like the battery-module conection xd).Try a 7-turn coil (12 gauge) on a 2S with the standard module, cap-reduced module, or a HalfPint module.
Any IH should do much more than 7 clicks with 2S 18650. Remember that the DynaCup was a 2S device and people liked that. I never counted clicks with 3S but 2S will be 2/3rd the clicks. It is simple math. It should push <200mwh per click or <1WH per bowl to the cap for diagnostic purposes.
Absolutely, that's what a buck is for. You can find high amperage DC motor controllers on EBay and Amazon that will do the job for $15-$20. You can also get a similar effect from using a PWM signal to a driver mosfet. The full buck is overkill for this scenario since the ZVS already has many of the same circuit elements. You can build a PWM controller or buy them.Can a buck converter fix the output voltage even though the input varies(lowers with usage)?
No I haven't, but I've followed the builds of other people who've done it. It seems to work fine. I think so long as you keep the frequency low, say <1 KHz, the mosfets shouldn't spend too much time in their linear range. The cap would need to be pretty big to have an impact but it might reduce stress on the ZVS.
