Abstract: The present invention provides an uninterruptable power supply system and method with a first AC source providing three-phase AC power, a DC source providing DC power, and a power converter receiving AC power from the first AC source and/or DC power from the DC source and delivering two wire DC power to a load via a DC output line. One pole of the DC output line is connected to the neutral reference of the four-wire AC-power supply line. The system may include a bypass device for passing power from its output side to the DC output line with the bypass device and the power converter being connected in parallel to the DC output line. The bypass device may include at least one switching unit, which receives AC power at its input side, and a control unit to supply pulsed power from an AC power supply.
