Original question:

AMC3330: HGND to be derived from the voltage divider circuit

hi,

in sbaa553 277V is rms voltage and must be divided by 0.7 for peak voltage

therefore peak voltage will be 277/0.7 = 395 Vpeak

and then VLL is about 1.7 * 395  = 671 volt

are i'm true?

best regard

    Hello,

    The paper describes these parameters. The line-to-line voltage between the two 277V sources is 480V and is reduced to 1V through the split-tap configuration. The equation to get the line voltage is:
