Royer induction heater – first test

This is the first test run of a royer induction heater running at 650 Watt, there is heavy voltage sag on the DC supply. The heated bolt is a M10x20mm. More to come when improvements are carried out.

    How can I change the frequency output to 50/60 Hz. Range. I would like to heat copper and have been told that 50/60 Hz. range is best for small copper parts. Having it be adjustable would be even better but not totally necessary.

    Thanks !

    Hi Nate

    You can not operate this circuit at such a low frequency, this runs in the region of 50kHz and up. You can adjust the frequency from changing resonant capacitor and work coil number of turns.

    You can still heat copper with this setup, 50Hz is not a golden ticket to heating copper.

    Kind regards
    Mads
