Methods and apparatus for providing uninterruptible power
First Claim
1. A power supply system comprising:
- a power input to receive input power from a power source;
a power output to provide output power to a load;
at least one battery having a battery output that provides battery power;
at least one power circuit coupled to the power input to receive the input power, coupled to the battery output to receive the battery power, and coupled to the power output to provide the output power from at least one of the battery power and the input power;
a first controller coupled to the at least one power circuit;
coupled to the first controller, and coupled to the at least one power circuit;
a first storage device associated with the first controller, anda second storage device associate with the second controller;
wherein each of the first controller and the second controller is configured to determine operational parameters of the power supply system; and
wherein the power supply system is configured to store a first set of parameters determined by the first controller and a second set of parameters determined by the second controller in each of the first storage device and the second storage device.

Abstract
Power supply systems and methods are provided. In one aspect, a power supply system includes a frame, a power input to receive input power from a power source, a power output to provide output power to a load, at least one battery module mounted in the frame and having a battery output that provides battery power, at least one power module mounted in the frame and coupled to the power input to receive the input power, coupled to the battery output to receive the battery power, and coupled to the power output to provide the output power from at least one of the battery power and the input power, a first controller coupled to the at least one power module, and a second controller, substantially similar to the first controller, coupled to the first controller, and coupled to the at least one power module, wherein each of the first controller and the second controller are configured to determine operational parameters of the power supply system and store a first set of parameters determined by the first controller and a second set of parameters determined by the second controller.

11. A method of controlling a power supply having a first controller and a second controller, the method comprising:
-
obtaining a first set of values corresponding to operational parameters of the power supply using the first controller; obtaining a second set of values corresponding to the operational parameters of the power supply using the second controller; storing the first set of values and the second set of values in a memory associated with the first controller; storing the first set of values and the second set of values in a memory associated with the second controller; designating one of the first controller and the second controller as a main controller and designating one of the first controller and the second controller as a redundant controller; controlling output power of the power supply using the main controller. - View Dependent Claims (12, 13, 14, 15, 16, 17)
