10kw Induction Heater Inverter Schematic
Microprocessor/PLL controlled driver
10kw Inverter for use with levitation and iron forging
Revised high power induction heater (2023). I was never happy with using the LM6172. A lot of noise go into the chip, messing with sampling values using the ardiuno routines.
I also tried using a comparator, but I guess my skills were not good enough. I was able to come up with a simple solution using a diode clamp and a resistor to limit the current from the
tank capacitor. The voltage range is 0 - 750Vrms and this is huge. A hex inverter squares the signal. Because it inverts the sine wave I have to flip the input signal into the hex inverter.
