Classification: CPC H  Y | IPC H

Claim 10:
11. A charging device comprising:
a Power Factor Correction (PFC) circuit including a first inductor, a second inductor and a third inductor connected to a first input terminal, a second input terminal and a third input terminal, respectively, and a first switch leg, a second switch leg and a third switch leg connected to the first inductor, the second inductor and the third inductor, respectively; and
a relay network including a plurality of relays, and
when the first input terminal, the second input terminal and the third input terminal are connected to each of three-phase loads, the relay network connects each phase of the three-phase powers to a 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 inverter, and
when a single-phase load 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 load to the first switch leg and the second switch legs, connects the third switch leg to a neutral point, and the PFC circuit is operated as a single-phase inverter.
