摘要： A charging device (1) includes a first auxiliary bridge arm (41) and a second auxiliary bridge arm (42). The first auxiliary bridge arm (41) is connected between a first port (21) and a second module (32). The second auxiliary bridge arm (42) is connected between the first port (21) and a third module (33). If the AC charging power (P) is three-phase, the first module (31) converts a first phase of the AC charging power (P), and the first auxiliary bridge arm (41) and the second auxiliary bridge arm (42) are disabled. Consequently, the second module (32) converts a second phase of the AC charging power (P), and the third module (33) converts a third phase of the AC charging power (P). If the AC charging power (P) is single-phase, at least a first module (31) is used to convert the AC charging power (P).
