Abstract
A power supply system for supplying power to a system load is described. The power supply system includes a plurality of power supply modules. Each power supply module includes a power-generating module, a unidirectional device, and a fan. When the power-generating module is in normal operation, the power generated by the power-generating module is sent in one direction to the system load through the unidirectional device. When the power-generating module fails, the fan is powered from a terminal connected to the system load.
Claims15
A power supply system for supplying power to a system load, the power supply system comprising:
- a plurality of power supply modules, wherein each power supply module comprises:
- a power-generating module for generating power to supply to the system load;
- a unidirectional device connected to the power-generating module at a first terminal and connected to the system load at a second terminal;
- and
- a fan for providing an air stream to dissipate the heat generated by the system load, the fan being connected to the second terminal of the unidirectional device;
- wherein (i) when the power-generating module is in normal operation, the power generated by the power-generating module is sent in one direction to the system load through the unidirectional device, and (ii) when the power-generating module fails, the fan is powered from the second terminal connected to the system load;
- wherein each second terminal of the power supply modules is coupled with one another to supply power to the system load.
A method for cooling a system load, the method comprising:
- coupling outputs of a plurality of power supply modules with one another to supply power to the system load, wherein each power supply module comprises a power-generating module and a fan.
- for one power supply module, using a unidirectional device as an output stage, the unidirectional device receiving power from a power-generating module and supplying power to the system load;
- and
- connecting the output of the unidirectional device to the fan of the power supply module;
- wherein when the power-generating module is in normal operation, the fan is powered by the power-generating module, and when the power-generating module fails, the fan is powered by the output of the unidirectional device connected to the system load.
A fan system for cooling a system load, the fan system comprising:
- a unidirectional device being connected to a power-generating module at a first terminal and connected to the system load at a second terminal;
- and
- a fan for providing an air stream to dissipate the heat generated by the system load, the fan being connected to the second terminal of the unidirectional device;
- wherein (i) when the power-generating module is in normal operation, the power generated by the power-generating module is sent in one direction to the system load through the unidirectional device, and (ii) when the power-generating module fails, the fan is powered by the second terminal connected to the system load.
