Induction Heater Melting Stuff
Because of skepticism about my home made induction by some people. I thought I'd add another video. This upgraded power supply uses a normal half-bridge IGBT inverter with a conventional configuration of induction heating. The heater melts a 50p coin and a chrome vanadium steel insert the Allen wrench. For those interested ... The frequency block is current working on the comments of the coil of a free-running oscillator, the two IGBT HGTG20N60A4D drive driven by a IR2184 chip. The key to the mergeruse of steel with low power and using fewer laps to reel working. molten steel is combined with a much higher resistance to cold steel and requires less energy efficient rotations. The current database has been used 13 amps at 240 V (3.1kw). IGBT peak current was 50 amperes at 120th kHz, the capacitors are the only critical component used csp150/200-i celem s '2 x 1.6uf
