UCC28180: Reference design for three phase input

Guru 19645 points
Part Number: UCC28180

Is there any reference design for 3-phase input? (The other than UCC28180 OK, including digital power)

Image of schematic is below, is this no problem?

※Vin: 200Vac, Vout: 400Vdc, Pout: 100W~kW order

Best regards,

Satoshi

  • Hello Satoshi,

    There is no reference design available for a 3 phase supply pfc..
    However it is possible to design a pfc circuit with the implementation as detailed in your drawing.
    If your  line to line voltage is 200Vac then the line to neutral voltage is 115Vac.
    This will be the same as using the UCC28180 in a single phase 115Vac supply
    except that you will have 6 times the line frequency on the DC side of the rectifers.
    You can use the Excel calculator tool with a 115Vac input in the design of your circuit.
    The calculator tool is located here.
