Hi,
Can we use UCC28070 for three phase applications. i mean with less Power Factor, can we achieve the high voltage regulation like 380VAC to 700DC of 6KW power. presently i am able to regulate the 680V output at one leg of interleave. but i f i connect both the legs of interleave , PWM is not getting turned on at both the legs. and with respect to laod also m not getting regulation even one leg also.
and is thier any thing like VINAC Pin should be SINE AC or we can give dc also to make it work as regulation.
Please help me to come out of this issue as i am stuck this with past 2 months.
