Abstract
A power adaptor (100) includes a power conversion unit (110) and a power line (121). The power conversion unit (110) charges a terminal (200) via the power line (121). The power adaptor (100) further includes a communication unit (130) and a data line (122). When the power adaptor (100) is coupled to the terminal (200), the communication unit (130) communicates with the terminal (200) via the data line (122). The power adaptor (100) charges the terminal (200) still using the power line (121). Furthermore, when the power adaptor (100) is coupled to the terminal (200), the power adaptor (100) communicates with the terminal via the data line (122). Compared with the method of data and power time-division multiplexing the power line, the heating phenomenon of the power line caused by an excessively high load of a signal isolation unit can be effectively avoided.
