UNINTERRUPTIBLE COOLING SYSTEM AND APPARATUS
First Claim
1. A cooling system including a compressor motor and a compressor operated by the compressor motor, the cooling system comprising:
- a first port configured for coupling with a primary power supply;
a second port configured for coupling with a secondary power supply, wherein the secondary power supply is a backup power source that allows the cooling system to operate when the primary power supply exceeds predetermined operating conditions;
a power circuit including a DC bus and a first plurality of switches, the DC bus coupled to the first port and the second port, the power circuit configured to deliver power from the first port and the second port to the DC bus and the first plurality of switches, wherein the first plurality of switches are configured to receive power from the DC bus and power the compressor motor; and
at least one control circuit configured to control power flow from the first port and power flow from the second port to the DC bus and the first plurality of switches, the at least one control circuit configured to control the compressor motor.

Abstract
A cooling system and power control apparatus provides an uninterruptible power supply. In one embodiment, the uninterruptible power supply provides power to an air conditioning system for cooling telecommunications equipment in the case of an AC power failure. Embodiments of the present invention include a first port configured for coupling with a primary power supply; a second port configured for coupling with a secondary power supply, wherein the secondary power supply is a backup power source that allows the cooling system to operate when the primary power supply exceeds predetermined operating conditions. A power circuit including a DC bus delivers power from the first port and the second port to a plurality of switches for controlling cooling equipment. A control circuit is configured to control power flow from the first port and power flow from the second port to the DC bus and the first plurality of switches.
