  • I know this topic is old, but anyway…
    The ‘old school’ trick for using 110 V equipment
    in 220 V power nets is a series DIODE !
    Choose a diode that can handle the current
    and put it in series in the power connection.
    You get 110 V half-wave ;-)
    Works well with transformer based supplies.
    You should always consider the particulars of
    the device you want to port, though.
    It might be prudent to dampen any ringing from
    the sharp corners of the wave, with a small cap.
    And you do have a unipolar halfwave, but as I said
    it works like a charm for transformer supplies.
    Hope this helps
    // Love
