Abstract:
A charging device may include a Power Factor Correction (PFC) circuit including first to third inductors connected to each of first to third input terminals, and first to third switch legs connected to each of the first to third inductors; and a relay network including a plurality of relays. 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, 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 and second switch leg, connects the third switch leg to the neutral point, and the PFC circuit is operated as an interleaved single-phase full-bridge PFC of single inductor type.
