Abstract
Uninterruptible Power Supply (UPS) systems and methods for a communications signal distribution system, such as a cable television (CATV) signal distribution system that distributes a communication signal and an Alternating Current (AC) power over a coaxial cable having a conductor and a sheath, include an input neutral line and an input voltage line. A first circuit is configured to convert an input voltage between the input neutral line and the input voltage line into first and second complementary Direct Current (DC) voltages. A second circuit is configured to convert the first and second complementary DC voltages into an AC voltage between an output neutral line and an output voltage line, and to connect the output neutral line to a coaxial cable sheath and the output voltage line to a coaxial cable conductor. The first and second circuits are configured to connect the input neutral line to the output neutral line without an intervening transformer winding.
