Method for a centralized external power supply with a built-in uninterruptible power supply

Disclosed is a method for a centralized external power supply (CEPS) with a built-in uninterruptible power supply (UPS). Benefits include consolidation to one power unit that is a UPS system and an external power supply for one or multiple PC systems and provides surge and black-out protection.

The popularity of purchasing UPSs for home PC systems has grown among end users. The disclosed method describes a centralized external power supply (CEPS) that contains a built-in UPS that has the capability to supply power to multiple PC systems and/or peripherals (see Figure 1). Two output options are possible:

·        The CEPS converts the 60-Hz line input to the appropriate DC output.

·        The CEPS converts the 60-Hz line input to high-frequency AC output.

The disclosed method provides several advantages, including:

·        Consolidation to one power unit that functions as both a UPS system and an external power supply.

·        Centralized power source to power multiple PC systems and/or peripherals.

·        Reduced PC cost by moving the power supply out of the PC chassis.

·        Reduced PC system size by removing the power supply from the system chassis

·        Built-in surge and black-out protection for a stationary system.

·        Reduced total cost for the external power supply and UPS system.

·        Improved incentives to the power supply vendors from selling a more advanced system.

·        Improved convenience for users because they may n...
