Embodiment Construction
[0047] figure 1It is a block diagram of an embodiment of the power level identifying circuit 10 , the power level marking circuit 20 and the power level power supply system of the present invention.
[0048] In this embodiment, the power level power supply system includes a power level identifying circuit 10 and a power level marking circuit 20 . The power level identification circuit 10 performs corresponding mode switching according to the signal level of the input power signal, including a first voltage conversion unit 101 , a first power interface 102 , a data processing unit 103 , a detection unit 104 , and a signal preprocessing unit 105 . The first power interface 102 is electrically connected to the first voltage conversion unit 101 for receiving a power signal and a power level coding signal. The detection unit 104 is electrically connected to the first power interface 102 and used for filtering the power signal in the first power interface 102 to obtain a power leve...
