Power Supply Selection Circuit of Green Computer

摘要

this is a small statue of the thai people is the detection means of the majority of the interrupt signal, the interrupt is combined with the use of the control signal to the output of the interrupt detection part and the interrupt detection part the control signal from the timer. the fixed time or more, the output of the function, if this judgment, the switching control signal output from the switch, and the switching operation of the main power supply according to the output of the auxiliary power supply part to supply the ac power supply in the power supply to supply the department of on the operation mode of the system is according to the supply voltage to control power consumption, reduce the computer's power supply is selected on the circuit.
