Abstract
A method for powering a computer system is disclosed. The method supplies power to a power distribution system in the computer using power components in the power supply when the power supply in the computer system is receiving AC power. When the AC power to the power supply is interrupted, at least one component in the computer system coupled to the power distribution system is powered down and power to the power distribution system is supplied using an energy storage device in the power supply for a holdup time H.
Claims15
A method of powering a computer system comprising:
- when a power supply in the computer system is receiving AC power:
- supplying power to a power distribution system from the power supply while charging an energy storage device inside the power supply;
- when the AC power to the power supply is interrupted:
- supplying power to the power distribution system using the energy storage device in the power supply for a holdup time H, and powering down at least one component in the computer system coupled to the power distribution system.
A computer system, comprising:
- at least one power supply coupled to, and configured to supply power to, a power distribution system;
- power distribution system is coupled to, and configured to supply power to, at least one component, and a controller;
- power supply comprises:
- DC/DC converter and energy storage device, wherein energy storage device is sized to provide a holdup time H when under a partial load Lp;
- when power supply is receiving AC power:
- energy storage device is charging and does not supply energy to power distribution system;
- when AC power flowing into power supply is interrupted:
- energy storage device supplies power to power distribution system;
- power supply is coupled to, and configured to send signals to controller, wherein the signals indicate when energy storage device is supplying power to power distribution system;
- controller is coupled to, and configured to send control signals to power distribution system, wherein the control signals enable/disable power to the at least one component.
A computer system, comprising:
- at least one power supply coupled to, and configured to supply power to, a power distribution system;

- power supply comprises:
- DC/DC converter and energy storage device, wherein energy storage device is sized to provide a holdup time H when under a partial load Lp;
- when power supply is receiving AC power:
- energy storage device is charging and does not supply energy to power distribution system;
- when AC power flowing into power supply is interrupted:
- energy storage device supplies power to power distribution system;
- power supply is coupled to, and configured to send signals to controller, wherein the signals indicate when energy storage device is supplying power to power distribution system;
- controller is coupled to, and configured to send a control signal to the at least one component, wherein the at least one component powers down in response to the control signal.
