AI Technical Summary

Problems solved by technology

This process, from the time the utility power goes out until the load is transferred to the generator, can take nearly 60 seconds, and in some cases much longer, thus dangerously disconnecting critical cooling systems A very long time
With today's higher density data centers, where critical loads (processors, storage, and communications) are kept online with battery-backed systems, cooling systems that are not kept online can potentially can cause critical loads to overheat, potentially dangerously in some cases
It is unwise to place pumps, fans, compressors or motors in a dedicated UPS system as computing equipment may suffer from poor line quality and / or noise

Embodiment Construction

[0006] figure 1 is a schematic diagram of a redundant DC power supply system, ie, system 100 . System 100 is configured as a 2N power system, where N is the number of power supplies required to properly support the power load. System 100 includes: generators 101A, 101B, rectifiers 105A, 105B, motor drives 111A, 111B, motors 113A, 113B, sensors 150A, 150B, and controller 155 .

[0007] Briefly, the system 100 provides DC power to the motor drives 111A, 111B which drive the motors 113A, 113B. Through the sensors 150A, 150B, the controller 155 monitors parameters related to the operation of the motors 113A, 113B, thereby controlling the motor drives 111A, 111B such that the sensed parameters remain within desired ranges.

[0008] The system 100 receives alternating current (AC) from utilities 102A, 102B. AC current from utility 102A is coupled through circuit breaker 122A and AC current from utility 102B is coupled through circuit breaker 122B. The circuit breakers 122A, 122B...

Abstract

There is provided a system that includes a power feed that distributes a direct current (DC) voltage in a building. The DC voltage is in a range of about 300 - 600 volts DC. The system also includes a motor, and a motor drive. The motor drive receives the DC voltage via the power feed, and from the DC voltage, derives an output that drives the motor.

Description

technical field [0001] The present invention relates to a highly reliable redundant direct current (DC) power system that provides modulated power to motors used in cooling data centers and critical infrastructure. Background technique [0002] Critical infrastructures, such as data centers, telecom centers and other infrastructures that require high-density, runtime-critical power supplies to handle storage and communications, are steadily increasing their power and cooling requirements. In these critical infrastructure applications, not only must reliable power be provided, but equally reliable cooling must be provided. If cooling fails, even for a short period of time, computer equipment can be severely affected. Furthermore, due to the enormous amount of energy used by these centers, systems must be designed and implemented that are not only resilient but also highly efficient. [0003] Traditionally, the power delivered to the motors that provide the movement of fluid...
