POWERSTAGE-DESIGNER: Formula Magnetizing Current

Bastien Bertrand

Part Number: POWERSTAGE-DESIGNER

Hello TI,

I would like to know the equation for the magnetisation current expressed in % in the application of a Full-Bridge Converter? I have the basic equation but I would like to know what you base this ratio on.

Thank you very much,

Bastien

    Bastien,

    Full-bridge is a double-ended, isolated buck derived topology. If you visualize the output LC filter as the output of a buck converter, we would assign the inductor current ripple to be anywhere between 20-40% of the maximum DC load current.

    Regards,
