| 摘要 |
The invention relates to a power-factor correction circuit for a three-phase power supply, wherein the correction circuit includes an input filtering unit receiving the three current phases, at least one inductance per phase located downstream from the filtering unit, a rectifying bridge powering a current splitting stage, characterised in that the filtering unit includes a differential-mode filtering cell including at least one induction circuit (511) made of a single magnetic material having a double E shape, each leg of the E being surrounded by a winding. The invention can particularly be used in the field of power electronics, in particular for making three-phase power supply units.
