一种刀片式微服务器的共享式电源电路
摘要：
本发明公开了一种刀片式微服务器的共享式电源电路，所述微服务器包括主板，所述主板上集成至少两个的节点；所述共享式电源电路包括电压变换电路I、电压变换电路II和至少两个的与门电路；节点的南桥芯片的SLP_S3#信号产生的PSON信号作为与门电路I的输入信号，所述与门电路I的输出信号依次传给进行电压变换的所述电压变换电路I和所述电压变换电路II，并将所述电压变换电路II的输出信号与所述节点的SLP_S3#信号经过与门电路II后作为所述节点的开机控制电压信号。在这种情况下，由于微服务器各节点消耗电流较小，本发明使各节点共用一套供电电路，以达到节省主板空间以及成本的目的。
摘要（英）：

The invention discloses a shared-type power supply circuit of a blade-type micro-server, wherein the micro-server comprises a main board, and at least two nodes are integrated on the main board; the shared-type power supply circuit comprises a voltage transformation circuit I, a voltage transformation circuit II and at least two AND gate circuits; and the PSON signal generated by the SLP-S3# signals of the south bridge chips of the nodes is used as the input signal of the AND gate circuit I, the output signal of the AND gate circuit I is sequentially transmitted to the voltage transformation circuit I and the voltage transformation circuit II which are used for performing a voltage transformation, and the output signal of the voltage transformation circuit II and the SLP-S3# signals of the nodes are used as the start-up control voltage signals of the nodes after passing through the AND gate circuit II. In this case, because the consumed current of each node of the micro-server is small, each node shares one power supply circuit according to the invention, so as to achieve a purpose of saving the space of the main board and the cost.
