Claim 10:
11. The control method of claim 10, wherein when the mains voltage is greater than or equal to the second threshold voltage and less than a third threshold voltage, the safety switch is switched on;
wherein when the rechargeable battery is not fully charged, the third switch is connected to the first switch, the first switch and the second switch are connected to the second terminal of the primary side of the transformer, the output switch is switched on, 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 third switch is connected to the second terminal of the alternating-current output, the output switch is switched off, the bidirectional converter is deactivated, and the charger is controlled to convert alternating current of the alternating-current input into direct current.
