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;
power circuitry 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 power circuitry; and
a second controller, substantially similar to the first controller, coupled to the first controller, and coupled to the power circuitry;
wherein each of the first controller and the second controller is 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.

25. A method of providing redundant control of an uninterruptible power supply having a first controller and a second controller, the method comprising:
-
determining a first set of values corresponding to operational parameters of the uninterruptible power supply using the first controller; determining a second set of values corresponding to the operational parameters of the uninterruptible 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; controlling output power of the uninterruptible power supply using the first controller; and upon failure of the first controller, controlling the output power of the uninterruptible power supply using the second controller. - View Dependent Claims (26, 27, 28)
