Shutdown prevention circuit under Windows environment

摘要

This research is about the computer power supply device,The operation of original woods environment or other application software can prevent improper power interruption and hard disk damage, and prevent power disconnection,Power supply consisting of switch power (2) and switch (3) to make DC ± 5V, ± 12V power so that the computer can use the external power supply (1) that can receive external power AC 110 / 220V and the input external power. In,When the windows environment or application software is running, the relay control unit (4) and of the induction signal;On the one hand, the contact point (51) of the socket (1) and other aspects connected by the switch force (2) and the relay (5) and the other side grounding coil (52) composed of the relay control part (4) and other aspects;Between the relay control unit (4) and the relay (5), under the windows environment composed of the controller power supply unit (6), the power supply is prevented from cutting off the circuit.
