    I'm building (trying to) a battery powered induction heating circuit. Most of the circuits I've seen rely on very large input voltages and output massive currents to large coils. I would prefer to have a circuit with a smaller coil, about 18 awg copper wire in the coil, and a smaller power supply, a Li-Po rechargeable battery. The inductive load in this case would be a small metal rod, about 2 mm in diameter, with a known resistance, so I think a PLL would be best. I also intend to use an arduino as the control board. However, I'm still not sure if this is feasible or which circuit would be best for this type of configuration.

    Based on the information on this site.

    It seems i have a few options, however, I am not sure which circuit schematic to base my design off of. Any advice would be greatly appreciated. :)

    You could google the "Marko induction noob heater" based on the very popular mazzilli oscillator, it can run on voltages from 12VDC up to around 50VDC.
