Claim 11:
12. The control method of claim 11, wherein when the mains voltage is greater than or equal to the third threshold voltage and is less than a fourth threshold voltage, the safety switch is switched on, the third switch is connected to the first switch, the first switch is connected to the second terminal of the primary side of the transformer, the second switch is connected to the tap of the primary side of the transformer, and the output switch switched on;
wherein when the rechargeable battery is not fully charged, the charger is deactivated and the bidirectional converter is controlled to convert alternating current of the secondary side of the transformer into direct current; and
when the rechargeable battery is fully charged, the bidirectional converter is deactivated and the charger is controlled to convert alternating current of the alternating-current input into direct current.
