Abstract
A multi-mode uninterruptible power supply (UPS) is provided. The multi-mode UPS includes a first path including a rectifier and an inverter, and a second path in parallel with the first path, wherein the multi-mode UPS is operable in an economy mode in which power flows from a utility to a load through the second path while at least one of the rectifier and the inverter is activated, the at least one of the rectifier and the inverter operable to perform at least one of DC voltage regulation, reactive power compensation, and active damping.
Claims20
A multi-mode uninterruptible power supply (UPS) comprising:
- a first path comprising a rectifier and an inverter;
- and
- a second path in parallel with said first path, wherein said multi-mode UPS is operable in an economy mode in which power flows from a utility to a load through said second path while at least one of said rectifier and said inverter is activated, said at least one of said rectifier and said inverter operable to perform at least one of DC voltage regulation, reactive power compensation, and active damping.
A power system comprising:
- a utility;
- a load;
- and
- at least one multi-mode uninterruptible power supply (UPS) coupled between said utility and said load, said multi-mode UPS comprising:
- a first path comprising a rectifier and an inverter;
- and
- a second path in parallel with said first path, wherein said at least one multi-mode UPS is operable in an economy mode in which power flows from said utility to said load through said second path while at least one of said rectifier and said inverter is activated, said at least one of said rectifier and said inverter operable to perform at least one of DC voltage regulation, reactive power compensation, and active damping.
A method of operating a power system, said method comprising:
- coupling a multi-mode uninterruptible power supply (UPS) between a utility and a load, wherein the multi-mode UPS includes a first path including a rectifier and an inverter, and a second path in parallel with the first path;
- and
- operating the multi-mode UPS in an economy mode in which power flows from the utility to the load through the second path while at least one of the rectifier and the inverter is activated, the at least one of the rectifier and the inverter performing at least one of DC voltage regulation, reactive power compensation, and active damping.
