Classification: CPC H  Y | IPC H

Claim 0:
1. A charging device comprising:
a Power Factor Correction (PFC) circuit including a first inductor, a second inductor and a third inductor connected to each of a first input terminal, a second input terminal and a third input terminal, and a first switch leg, a second switch leg and a third switch leg connected to each of the first inductor, the second inductor and the third inductor; and
a relay network including a plurality of relays,
wherein when the first input terminal, the second input terminal and the third input terminal are connected to each phase of three-phase powers, the relay network connects each phase of the three-phase powers to the corresponding one among the first switch leg, the second switch leg, and the third switch leg, and the PFC circuit is operated as a three-phase boost PFC, and
when a single-phase power is connected to one among the first input terminal, the second input terminal and the third input terminal, the relay network connects the single-phase power to the first switch leg and the second switch leg, connects the third switch leg to a neutral point, and the PFC circuit is operated as an interleaved single-phase full-bridge PFC of a single inductor type.
