Power classification device for personal computers, has control device connected with switching element to produce control signal for controlling switching element to enter into switch on state or switch off state

摘要

The device (200) has a switching element (206) i.e. bidirectional switch, comprising connecting terminals connected with output connections of main supply circuit-modules (202) with power conversion rates to selectively classify power of main and auxiliary power loads (212, 214) corresponding to switch on and off states of the switching element. A control device (208) is connected with the switching element to produce a control signal for controlling the switching element to enter into the on state or the off state. One power conversion rate is higher than the other power conversion rate.
