Abstract
Systems, apparatuses, and methods are described for a versatile UPS. The versatile UPS is operative to provide power to a load and to an interconnected network for delivering electricity from producers to consumers (i.e., an electricity grid, or simply, “a grid”). The versatile UPS has a plurality of switches providing for a multiplicity of switching states. The output to the load, the grid, or both is dependent, at least in part, on the switching states. Related systems, methods and apparatus is also described.
Claims19
An apparatus comprising:
- an uninterruptible power supply (UPS) comprising:
- a load terminal;
- a first alternating current (AC) terminal, configured to provide input AC power to a first power converter;
- a second AC terminal, configured to provide additional input AC power to the load terminal;
- the first power converter connected to a battery and to a second power converter;
- the second power converter connected to the load terminal;
- a first switch circuit disposed between the first AC terminal and the first power converter, wherein the first switch circuit comprises a first switch, a second switch, and a first silicon controlled rectifier (SCR), wherein the first switch and second switch are disposed in series between the first AC terminal and the first power converter, and wherein the first SCR is disposed in parallel to the second switch;
- a second switch circuit disposed between the second AC terminal and the load terminal;
- and
- one or more controllers configured to operate the first switch circuit, the second switch circuit, the first power converter, and the second power converter in a plurality of operating modes.
