3 POWER FACTOR CORRECTION CIRCUIT FOR THREE-PHASE POWER SUPPLY

摘要

The present invention relates to a power factor correction circuit for a three-phase power supply. The correction circuit includes a filtering unit at an input for receiving three phases of current, at least one inductor per phase located downstream of the filtering unit, a rectifying bridge for powering the current-chopping stage, Mode filtering cell comprising at least one inductive circuit 511 formed of a single magnetic material at a double E, each leg of E being surrounded by a winding. The invention is particularly applicable in the field of power electronics and in particular applies to the manufacture of three-phase power supply units.
