Abstract: A method of servicing a computer system without interrupting operation of th e computer system, by connecting a computer component to a board of the comput er system, detecting connection of the computer component to the system board using a control circuit, supplying power to the voltage input of the compute r component in response to detecting the connection, and thereafter monitoring the power supplied to the voltage input of the computer component. The metho d may be used for core computer components such as CPU modules and voltage regulator modules. Power to the voltage input of the computer component is turned off in response to a determination that a current level of the power supplied to the voltage input exceeds a specified level. A fault signal is latched in an active state in response to the determination; the fault signa l is reset when the component is removed from the system. The method also applies to a plurality of hot-pluggable components, wherein the power suppli ed to each component is individually monitored.

Abstract: A power subsystem for a computer system allows a voltage regulator module (VRM) to be removably connected to a system board, while limiting disturbances on the voltage rails of the system board. The electrical disturbances are prevented by charging voltage outputs of the DC/DC circuit of the VRM prior to directly connecting the voltage outputs to the voltage rails. To ensure that the voltage outputs are properly charged, a VRM connector may be used in which the voltage output pins are shorter than charge pins which are coupled to respective capacitors and to the voltage outputs of the DC/DC circuit. In this manner, as the connector is mated with a corresponding connector on the system board, the capacitors are first charged via resistive paths connected to the voltage rails, prior to directly connecting the voltage outputs to the voltage rails. The VRMs are thus "hot-pluggable," enabling a user to upgrade or service the system with no interruption.

Abstract: A D.C.-to-D.C. converter that employs a current switch chopper with the collectors of two switching transistors feeding opposite ends of a primary of a step up transformer. The transformer has a secondary which resonantly feeds back voltage to the bases of the two switching transistors for converting the voltage from D.C. to A.C. and includes floating comparator means sensing the voltage at the collectors of these transistors to regulate the magnitude of the voltage by comparing that voltage with a reference voltage and then readjusting the current supplied to the floating emitters of the two switching transistors by a third transistor.
