Power Supply Configuration System and Method

摘要

A power supply configuration system/method providing a digitally controlled uninterruptable power supply (UPS) to protected load devices (PLD) configured as power supply units (PSU) serviced by one or more power supply sources (PSS) is disclosed. The system generally includes a number of power supply sources (PSS) that are monitored by power condition sensing (PCS) circuitry that determines individual power source states within the PSS. This physical state information is used by a digitally controlled switching network (DSN) that reconfigures the electrical connections between the PSS and the individual PLD elements to properly route power from the PSS to the PLD in the event of individual PSS failures. The DSN receives phase/voltage state information from the PSS to ensure that current between the PSS and PLD is transferred in a synchronized manner and that PSS resources are properly protected during the switching transition.

1. A power supply configuration system comprising:
(a) primary power source (PPS) means; (b) secondary power source (SPS) means; (c) power condition sensing (PCS) means; (d) digitally controlled switching network (DSN) means; (e) power supply unit (PSU) means; (f) protected device load (PDL) means; and (g) AC+DC power supply (ADP); wherein said PCS means is configured to sense the power state condition (PSC) of said PPS means and generate a phase power condition (PPC) status that is electrically coupled to said DSN means; said DSN means is configured to electrically couple said PPS means or said SPS means to said ADP based on the state of said PPC status; said PSU means comprises an AC+DC power supply (ADP); said ADP comprises a boost converter (BCV) further comprising: a BCV input port and BCV output port; said BCV is configured to accept AC or DC voltage input at said BCV input port; said ADP comprises a DC-DC converter (DDC) further comprising: a DDC input port and DDC output port; said BCV output port is electrically coupled to said DDC input port; said PDL means comprises a DC-DC power supply (DDP) electrically coupled to a protected load device (PLD); and said DDC output port is electrically coupled to and supplies power to said DDP.
