During the couple in adapter of port, controller 1 can turn off all voltage changing module components 5, and connect this and be connected with connectivity port and electricity
Circuit between power supply module 3.Because when only an adapter accesses the connectivity port of electronic equipment, just not
The different multiple power of voltage be present, also avoid the need for being transformed into the operation of identical voltage.And supply of electric power module 3 is performing
When power supply and charging operations, the first electrical power conversion that can also export the adapter of the connection is required electric power, now may be used
So that directly the first power transmission of input to supply of electric power module 3 to be handled.
Specifically, the switch module 7 in the embodiment of the present invention can be connected to the connectivity port including corresponding respectively
Multiple sub switchs between supply of electric power module, also, controller 1 can only exist a connectivity port connection detecting
When having adapter, the connectivity port and supply of electric power module are connected by sub switch corresponding to regulation.
