ABSTRACT:
In a partitioned power converter system having a central uninterruptible power supply ("UPS") stage couplable between a commercial power source and a peripheral stage, the central UPS stage including a primary converter that converts commercial power from the commercial power source to a distribution voltage; a battery boost converter, coupled to a battery reserve system, that boosts a battery voltage produced thereby to the distribution voltage; and mode switching circuitry that alternatively couples one of the primary converter and the battery boost converter to the peripheral stage, selective bypass circuitry and a method of increasing the efficiency of the power converter system. The selective bypass circuitry includes: (1) a controller for determining a load on the battery boost converter and (2) a bypass circuit, coupled to the controller, for coupling the battery reserve system directly to the peripheral stage when the battery boost converter is loaded less than a preselected lower limit, the bypass circuit thereby bypassing the battery boost converter and eliminating inefficiency associated therewith under light load conditions.
