摘要： A method of upgrading firmware of an adapter includes transmitting a set of n data blocks of first upgrade file to the adapter, receiving a first response information of the adapter based on the set of n data blocks, and determining that the updating procedure of the adapter fails when the first response information indicates that the adapter fails to receive all of the n data blocks. In the method, a mobile terminal transmits the upgrade file to the adapter and the adapter sends determination information to the mobile terminal after the adapter receives the upgrade file having a predetermined size. In a time interval, if the mobile terminal fails to receive the determination information or the adapter does not receive the upgrade file, the upgrading firmware of the adapter fails.

摘要： Provided are a power supply circuit, a power supply device and a control method. The power supply circuit includes a primary rectifier unit, a modulation unit, a transformer, a secondary rectifier and filtering unit, a current feedback unit, an isolation unit and a control unit. The power supply circuit removes a liquid electrolytic capacitor at a primary side. In the power supply circuit, the liquid electrolytic capacitor at the primary side is removed, such that a volume of the power supply circuit is smaller, and is safe to use. Moreover, the control unit may determine a type of a voltage of input alternating current, and set a current limit value in the current feedback unit according to the type of the voltage of the alternating current.
