Power factor correction device and apparatus for converting a three-phase alternating current into a direct current

A power factor correction device comprising:

• a power supply side which is connectable to a source of alternating current, the power supply side including at least a first terminal and a second terminal, which are connectable to a phase and to a neutral of said source, respectively;
• an output side which is connectable to a direct current load and which includes a positive voltage terminal and a negative voltage terminal;
• at least a first power inductor electrically connected in series to said first terminal of the power supply side;
• a rectifier operatively interposed between said power supply side and said output side and comprising:
• a diode bridge configured to convert the alternating current into a direct current towards the load;
• one or more switches which are selectively switchable between an open configuration and a closed configuration to switch the rectifier between a first configuration, in which said rectifier interrupts a current flow towards the output side and charges said first power inductor, and a second configuration, in which said rectifier allows the current flow to the load and discharges said first power inductor;
• a second power inductor electrically connected in series to said second terminal of the power supply side;
• wherein said first power inductor and said second power inductor are magnetically coupled to each other such that the current flowing in the first power inductor flows in a same direction as a current flowing in the second power inductor.
