Title: METHODS AND EQUIPMENT FOR PROVIDING BACKUP POWER IN CELLULAR BASE STATIONS
Abstract:
A load accumulator for a cellular base station antenna includes a plurality of input terminals configured to receive a plurality of input voltages, a plurality of output terminals configured to be coupled to a respective plurality of tower top equipment and configured to supply output voltages to the tower top equipment, a plurality of switches coupled to respective ones of the plurality of input terminals and the plurality of output terminals; a voltage sensor coupled to at least one input terminal of the plurality of input terminals and configured to sense a level of one of the plurality of input voltages received at the at least one input terminal, a supplemental input terminal configured to receive a supplemental voltage, and a control logic coupled to the voltage sensor and to the plurality of switches and configured to detect that the supply voltage supplied to the at least one input terminal has fallen below a threshold voltage, and in response to detecting that the supply voltage supplied to the at least one of the plurality of input terminals has fallen below the threshold voltage, to supply the supplemental voltage to a respective one of the plurality of output terminals.
