View Patent ↗An uninterruptible power supply (UPS) system that may incorporate a battery subsystem including at least one battery for generating electrical power, and a UPS subsystem including at least one power module. At least one first bus system may couple the battery subsystem to the UPS subsystem to supply electrical power to the UPS subsystem.
