摘要： An electrical power transfer system for selectively connecting a load to a first power source or a second power source includes a first switch having an input selectively connected to the first power source and an output connected to the load. A second switch includes an input and an output connected to the load.

摘要： An uninterruptible power supply (UPS) may include direct cooling for various components of the UPS that generate heat. The direct cooling may be part of a cooling system that directs the generated heat to the ambient environment external to the room or building housing the UPS such that the heat load of the UPS places a minimal or zero load on the air-conditioning system for the room within which the UPS is located. The cooling system can utilize multiple cooling loops to transfer the heat from the heat-generating components of the UPS to the ambient environment.

摘要： An uninterruptible power supply system (100) has a flywheel system/battery combination (106) as a source of back-up DC power. When power is restored after a power outage, a controller (302) of the uninterruptible power supply system (100) controls the rectifier (102) to keep its DC output voltage sufficiently low so that only the flywheel system (118) of the flywheel system/battery combination (106) is initially recharged. Once the flywheel system (118) is recharged, the controller (302) is configured to raise the voltage of the rectifier's DC output voltage to the nominal DC output voltage of the rectifier (102), both for recharging the battery pack (116) of the flywheel system/battery combination (106) and to provide DC power to an inverter (104) of the uninterruptible power supply system (100).
摘要翻译：不间断电源系统（100）具有作为备用DC电源的飞轮系统/电池组合（106）。当停电后恢复供电时，不间断电源系统（100）的控制器（302）控制整流器（102）使其DC输出电压保持足够低，使得只有飞轮系统的飞轮系统（118） /电池组合（106）最初被充电。一旦对飞轮系统（118）进行再充电，控制器（302）被配置为将整流器的DC输出电压的电压升高到整流器（102）的额定DC输出电压，两者用于对电池组（116）进行再充电飞轮系统/电池组合（106），并且向不间断电源系统（100）的逆变器（104）提供直流电力。

摘要： A centralized cooling system can selectively deliver individualized cooling to individual electrical load units. The system can provide direct cooling from a manifold of cooling outlets in a controlled manner based on the sensed electrical loads of particular load units. A branch monitoring system monitors the load on electrical feeds that are coupled to electrical load units. A controller is coupled to the branch monitoring system and provides output to control a cooling unit. At least one control valve is further coupled to the controller downstream of the cooling unit generally at each cooling outlet to control an amount of cooling fluid, such as air or liquid, directed to one or more of the units. If a load changes for a given unit, the controller can actuate a cooling valve coupled to a corresponding cooling outlet and alter the amount of cooling fluid flowing into or around the unit(s).
