Tim, your efforts are are very impressive and you are a super sharp guy but I think that a lot of these people looking at your stuff would like a very clear explaination on the basics of how it works. From begininning to end. Make it easy to understand for someone like me who has no grasp of induction heating.
I'm also interested in purchasing one of these, I happened upon a forum where i heard you might be selling them. Im looking for something under 500$. im looking for something that can melt steel (not necessarily in large quantities). Thanks if you could get back to me I'd appreciate it.
@luthmhor Im willing to go up to around 800$ i for a unit capable of melting steel, the ones im finding on the internet are all over 2500$, but are made for continual use over several years (like in a machine shop)
Use should use adequate ventilation to prevent zinc poisoning from the galvanic coating. Not sure if your heater is getting up to the 1650 F for vaporization, but you really don't want to chance welders lung as its nasty. I have read of a welding teacher dying of pneumonia caused due to inadequate ventilation whilst burning the zinc off some steel rods in an oven, really

Love this. Good job. Is there any chance that you can build that for in some box and put that for sale? I will be interested to buy something like that. pat.
@Jadeintune yes people should know heating up anything galvanized such as this pipe or a "tin" garbage creates toxic fumes that can be deadly. Look up "metal fever"
burning galvanized metel can kill you

heating up galvanized zinc i dont think is very good for you

@mrhockey50 yeah 1 whiff could kill you.

Then according to this, what is the best configuration for the output stage as the tank circuit? a series or parallel.
¿How these settings affect the impedance matching?
Tanks

What is the current shown in the second channel of the oscilloscope?
UltraDavidson37 9 months ago
@UltraDavidson37 Inverter current. If I recall correctly... 20A/div scale?

For example..... The signal starts here at the PWM chip and then it goes here and this happens.

I hope that wasn't galvanized steel; that's toxic when burned.

crap this is advanced lol. i thought you just plugged a coil into the wall outlet

just so you know galvanized steel produces a toxic gas... it can kill you

This may be a stupid question but is the coil only able to heat up metallic objects? For example can you put your finger in there and burn it?
biowerks 2 years ago
No, a finger isn't conductive enough to feel anything from this heater (but do beware of rings!).
RF heaters (running at 10MHz+) generate enough voltage to be dangerous by electric shock, RF burns and induction.

I am currently designing an induction heater almost exactly like this one, except I am phase locking the inverter to the tank.

Is this IGBT?
alexsgarage 2 years ago
Yes. Although at this voltage, there are plenty of MOSFETs that'll work too.
T3sl4 2 years ago
Very nice, how much did this cost to build, and is there a chance that I can get a schematic for this circuit?
alexsgarage 2 years ago
It costs 100-300 bucks, depending on how much you have on hand / buy / salvage.
Old schematics are on my website, current plans are for available.
