In this embodiment, the intelligent conversion circuit 1 solves the problem that the conventional notebook computer cannot communicate with the power adapter 3 based on the USB Type-C in protocol during charging, and during charging, the quick charging protocol IC10 replaces the notebook computer to communicate with the protocol controller in the power adapter 3 by detecting the charging voltage and the charging current at the output end of the power adapter 3, so that the power adapter 3 outputs the charging voltage suitable for the notebook computer. In addition, because the adapter 2 comprises a DC plug 20 and an interface conversion structure which can be inserted into the charging jack of the notebook computer to be charged, the problem that the charging jack of the traditional notebook computer cannot be matched with the output interface of the USB charger is solved through the adapter 2. Therefore, by using the charging switching structure of the notebook computer based on the USB Type-C, the existing notebook computer and the USB Type-C power adapter 3 are not required to be improved in the original structure, and the USB Type-C power adapter 3 can be used for charging the notebook computer, so that a user can get rid of the trouble of different configurations of different traditional computers, and the use and the sale are very convenient. In addition, the intelligent conversion circuit 1 in the present embodiment may be provided in the power adapter 3, or may be provided in the DC plug 20. The power adapter 3 may be an AC-DC adapter or a DC-DC adapter.

As shown in fig. 4 and 5, the power adapter 3 includes a power input terminal 30, an AC-DC converter 31, a fast charging protocol controller 32, a switching circuit 33, and a Type-C interface circuit 34. During charging, the quick charging protocol IC10 in the above embodiment is communicatively connected to the Type-C interface circuit 34 through the CC line, and the positive electrode line and the negative electrode line in the DC plug 20 are electrically connected to the positive electrode terminal V + and the negative electrode terminal V-of the Type-C interface circuit 34, respectively. The voltage detection circuit 11 is used for detecting whether the voltage called from the power adapter 3 by the quick charge protocol IC10 through the CC line is within a required range, and includes a voltage detection line 110, one end of the voltage detection line 110 is electrically connected to the quick charge protocol IC10, and when charging, the other end of the voltage detection line 110 is electrically connected to the positive terminal V + of the Type-C interface circuit 34.
