Abstract
Status of a bypass source of parallel-connected UPSs is determined from a load share when a loading of the parallel-connected UPSs meets a predetermined criterion. Status of a bypass source of the parallel-connected UPSs is determined from a bypass source voltage when the loading of the parallel-connected UPSs fails to meet the predetermined criterion. The loading may include an aggregate loading, and failure of a bypass source of a UPS may be identified responsive to detecting that a load share of the UPS is less than a predetermined proportion of the aggregate loading. Alternatively, failure of the bypass source may be identified by detecting that a bypass voltage fails to meet a predetermined criterion. Bypass circuits of the UPSs may be controlled responsive to a load share and/or a bypass source voltage.
