Abstract

Power supply apparatus for a telecommunications base station disclosed. The power supply apparatus comprises means for receiving an AC mains power supply (10), conversion means (18; 60; 70; 72) for converting the AC mains power supply to a DC voltage, a DC bus (20) for supplying DC power to at least one DC load (22, 24) in the base station, and a standby generator set (34). Means (14) are provided for detecting an irregularity in the mains power supply, and power for the base station is supplied from the standby generator set on detection of an irregularity in the mains power supply. The standby generator set (34) is a variable speed generator set, and the conversion means is operable to convert an output of the variable speed generator set to a substantially constant DC voltage to supply the DC bus when the base station is powered by the variable speed generator set.
