Abstract:
1. A power conditioning system for providing clean and uninterrupted power to loads, comprising: a cabinet; an input circuit including a passive filter for receiving three phase AC power; an AC to DC converter receiving AC power from said input circuit; a regulating DC to DC converter receiving DC power from said AC to DC converter; a high frequency DC to AC inverter; an output circuit including a passive filter receiving power produced by said high frequency DC to AC inverter; two banks of batteries, said system configured to receive DC power from either of said banks to produce AC power by said high frequency DC to AC inverter such that the connection of both battery banks is not necessary to operate said high frequency DC to AC inverter, said system further configured to allow replacement of batteries in one of said banks while supplying power to said high frequency inverter from another of said battery banks, further wherein said banks are organized in a front and rear vertical rack, each rack providing access to each individual battery without the removal of other batteries, wherein the front rack may be swung about a pivot point near the bottom of the rack to provide access to the rear rack; a battery charging circuit receiving internal DC power, said battery charging circuit connected to provide charging for said batteries; and wherein said AC to DC converter is configured to operate using either 400 or 480 volt AC three phase input power.
