摘要： Systems and methods of controlling an uninterruptible power supply are provided. The uninterruptible power supply includes an input configured to receive input power having three phases, an output configured to provide output power, a power conversion circuit coupled with the input and the output, one or more sensors configured to monitor one or more parameters related to the output power, and a controller coupled with the power conversion circuit and the one or more sensors. The controller is configured to receive, from the one or more sensors, values for the one or more parameters, and based on the values for the one or more parameters, select a number of phases of the input power for receiving power for the power conversion circuit.

摘要： Methods and systems for detecting and identifying faults in air-cooled systems are provided. The systems and methods may utilize a prediction model based on an energy balance relationship. In certain methods, one or more measured parameters associated with the air-cooled system may be compared with corresponding parameters generated by the prediction model. One or more faults may be detected and identified based upon deviations between the measured and detected system parameters.

摘要： Systems and methods for controlling a UPS system to adapt to power availability requirements and to increase the ef- ficiency of the UPS system are disclosed. The UPS system may include a modular UPS system or a parallel UPS system having a plurality of units. One method of controlling the UPS system includes obtaining actual power consumption by a load coupled to the UPS system, determining a log based power schedule in response to obtaining the actual power consumption and determining power availability for the UPS system in response to determining the log based power schedule. The method may further include adjusting a power capacity of the UPS system based on the power availability, by hibernating or activating at least one unit of the plurality of units of the UPS system.

摘要： An uninterruptable power supply (UPS) is provided. The UPS includes a first input constructed to receive input power from a first power source, a second input constructed to receive input power from a second power source, an output constructed to provide output alternating current (AC) power derived from at least one of the first power source and the second power source, an inverter coupled to the first input, the second input, and the output and constructed to generate the output AC power, and a controller coupled to the inverter. The controller is configured to identify one or more harmonics in the output AC power, generate an inverter reference signal, and modulate the inverter reference signal to reduce harmonic distortion contributed by the one or more harmonics.
