  • Boost-input backed-up uninterruptible power supply
    Patent number: 5684686
    Abstract: A boost-input backed-up uninterruptable power supply from an input voltage source, such as a 60 cycle 120/240 Vac service, provides an uninterrupted output voltage to a load connected to a return. The backed-up power supply has an input rectifier and low energy storage filter coupled to the input voltage source for converting the input voltage source into at least an unregulated positive dc voltage source, and an unregulated negative dc voltage source. Each respective unregulated source has a respective unregulated dc voltage value with respect to the return. Two 120V battery stacks provides respective positive and negative battery voltages at corresponding positive and negative battery output terminals.
