Due to scepticism about my home made induction heater by some people. I thought I would add another video. This updated power supply uses a normal half bridge igbt inverter with a conventional induction heating setup. The heater melts a 50p coin and a crome vanadium steel allen-key socket. For those interested...The frequency lock is achieved using work coil current feedback to a free running oscillator which drived the two hgtg20n60a4d igbts through an ir2184 drive chip. The secret to melting steel at low power is to use less turns on the work coil. Molten steel has a much higher resistance than cold steel and requires less turns to couple energy to efficiently. The current used here was 13 amps at 240v (3.1kw). Peak igbt current was 50 amps at 120 khz. The capacitors are the only critical component- i used celem csp150/200 's 2 x 1.6uf

    you cant melt flesh, it burns and make a nasty smell.

  • yes- there are ...

    yes- there are loads! The ir2111 will do for low powers. You can also use a chip like the sg3525 (lots of chips in this family) to generate the waveforms- you will then need to use either an ir2110 or some gate drive transformers to do the level conversion for the half bridge. If i were you i would stick to the 2184 (newark/farnell, digikey etc should stock it) since it is really simple and cheap.

  • sorry kimladha it ...

    sorry kimladha it is the final question!is there any way,any circuit that generate dead time whithout using ir2184?i could not find this IC.
