G. Olivier et al., NOVEL TRANSFORMER CONNECTION TO IMPROVE CURRENT SHARING IN HIGH-CURRENT DC RECTIFIERS, IEEE transactions on industry applications, 31(1), 1995, pp. 127-133
This paper presents a novel, nonconventional family of converters for
low-voltage, high-current applications based on a peculiar series conn
ection of the primary windings. On the secondary side, all the semicon
ductors are directly connected in parallel without resorting to the us
e of interphase transformers or any other current sharing means. The s
eries connection of the primaries ensures current sharing while zigzag
arrangement provides the desired pulse number.
