Abstract
An uninterruptible power supply (UPS) includes a first battery set and a second battery set. The UPS includes a charging circuit to charge the battery sets using alternating current (AC) power. The UPS includes a slot receptive to insertion of different types of output modules that each include an inverter to convert direct current (DC) power from the first and second battery sets, including a first type that connects the first and second battery sets in parallel and a second type that connects the battery first and second sets in series.
Claims15
An uninterruptible power supply (UPS) comprising:
- a first battery set and a second battery set;
- a charging circuit to charge the first and second battery sets using alternating current (AC) power;
- and
- a slot receptive to insertion of different types of output modules that each include one or more of an inverter and a converter to convert direct current (DC) power from the first and second battery sets, including a first type that connects the first and second battery sets in parallel and a second type that connects the battery first and second sets in series.
A removable output module for an uninterruptible power supply (UPS), comprising:
- a pair of first inputs to connect to a pair of outputs of a first battery module of the UPS;
- a pair of second inputs to connect to a pair of outputs of a second battery module of the UPS;
- a plurality of conductors to connect the first and second battery modules in one of parallel and series;
- and
- one or more of an inverter and a converter to convert direct current (DC) power from the first and second battery modules.
A method comprising:
- providing an uninterruptible power supply (UPS) having a first battery string and a second battery string and receptive to any of a plurality of different output module types including:
- a first type that connects the first and second battery strings in parallel and converts first DC power from the first and second battery strings to first AC power;
- a second type that connects the first and second battery strings in parallel and converts the first DC power from the first and second battery strings to second AC power;
- a third type that connects the first and second battery strings in series and converts the DC power from the first and second battery strings to the second AC power;
- and
- a fourth type that connects the first and second battery strings in series and converts the DC power from the first and second battery strings to second DC power;
- choosing a selected output module types as one of the first, second, third, and fourth types, based on whether the first and second battery strings are to be in series or in parallel, and then based on whether a DC-to-DC converter is to be included;
- and
- installing a removable output module of the selected output module type within the UPS to form a complete electrical circuit between the first and second battery strings within the UPS.
