    I'm trying to make a 3phase PFC circuit based on this schematic:

    " PFC/3-phase vienna rectifier.jpg"

    more info about this circuit:

    " PFC/3phase PFC using vienna rectifier.doc"

    I'm doing a test in ltspice with this circuit and three single phase PFC
    controller IC's (ie. LT1249) but am not sure how to wire up these IC's
    to detect the input phases bipolar voltages and currents, as for single
    phase the input voltages and currents are just positive.

    Here is the ltspice circuit so far:

    " PFC/3phase ltspice"

    Are there any 3phase PFC controller IC's out there?
