Provided in the embodiments of the present disclosure are a method for detecting short circuit of a discharger in a parallel UPS system and a parallel UPS system. The method includes: controlling a charging switch of a battery charger in a target UPS submodule to be closed in a case where the parallel UPS system operates under a condition of mains input without any battery, where the target UPS submodule is any UPS submodule from the at least two UPS submodules; and detecting, for each of the UPS submodules, a current on a common battery input side of the UPS submodule, and determining whether a discharger in the UPS submodule is short-circuited based on the current on the common battery input side of the UPS submodule.

A system and method for continuous real-time monitoring of charge levels, e.g., fluid refrigerant available within a refrigerant reservoir of a pumping apparatus for a two-phase cooling system, receives power data corresponding to a current load drawn by each server or information technology (IT) device served by the pumping apparatus. Based on the received power data, the controller infers the expected charge level, e.g., the proportion of fluid refrigerant that should be remaining within the refrigerant reservoir as opposed to circulating in the secondary fluid network of the cooling system, and compares the expected charge level to an actual current charge level sensed within the refrigerant reservoir, initiating a gentle system shutdown and/or generating an alert if the actual charge level sufficiently deviates from the expected charge level based on the received power data.

A system and method for smart pre-cooling in a single-phase or two-phase cooling system maintains a thermal buffer tank in fluid communication with the primary and secondary fluid networks of the cooling system (as applicable) wherein a fluid thermal buffer may be stored to provide reserve cooling capacity. A controller of the cooling system receives weather data, e.g., ambient temperatures for one or more segments of an hour, day, week, or other predetermined duration. For each segment, based on forecasted ambient temperatures, the controller may direct the thermal buffer tank to charge or use reserve cooling capacity to minimize overall energy consumption. For example, when temperatures are lower the thermal buffer tank may charge additional cooling capacity, and when temperatures are higher the thermal buffer tank may deploy reserve cooling capacity to reduce the burden on other chiller devices in removing heat from the system.

Star-delta convertible connector (200) and method of operating the same for selectively establishing a star configuration or a delta configuration in a three-phase power distribution system are disclosed. The connector includes a socket assembly (202) having multiple receptacles electrically coupled to corresponding terminals and arranged to receive phase conductors and, selectively, neutral conductors, as well as an interchange plug receptacle. The interchange plug (204) includes prongs carrying at least one conductive busbar (222) configured to establish different electrical interconnections based on plug orientation. In a first orientation, the busbar electrically interconnects phase conductors with neutral conductors to establish a star configuration, and in a second orientation, the busbar electrically interconnects phase conductors with one another to establish a delta configuration. Switching between configurations is accomplished by removing the interchange plug, reorienting the interchange plug by approximately 180 degrees, and reinserting the interchange plug, without rewiring, disassembly, or removal of the socket assembly.

A system for operating a circuit breaker is disclosed. The system includes a shunt coil configured to trip a circuit breaker. A first voltage source is configured to produce a first voltage and second voltage source configured to produce a second voltage. A voltage selection circuit configured to select one of the first and second voltage sources. A shunt drive circuit configured to drive an actuation voltage to the shunt coil based on a selected one of the first and second voltages.

A system and method for power aware thermal management of a data center environment including IT devices receiving operating power from power distribution units (PDU) may include sensing current cooling capacity of a cooling system including chiller devices for transferring thermal energy generated by the IT devices by circulating a fluid refrigerant through the IT devices via a fluid network. Similarly, the PDUs may sense and report current operating power distributed to the IT devices. A cooling system controller may, when current power distribution data sufficiently deviates from the current cooling capacity (e.g., indicative of an imminent surge or drop in power and a corresponding shift in heat load), direct the chiller devices to adjust device setpoints to proactively address the imminent shift in heat load within the fluid network.

A power distribution panel (100) can include a cabinet (110), two or more breakers (120) at least partially disposed within the cabinet (110), and one or more busbars at least partially disposed within the cabinet (110). The busbars can include one or more line busbars (152), one or more neutral busbars (158), and one or more ground busbars (164). The breakers (120) and/or busbars can be selectively coupled to each other and/or selectively isolated from each other.

A cooling system can include a first cooling loop for extracting heat from a load, a second cooling loop for rejecting the heat, and a controller for controlling one or more aspects of the first cooling loop and/or the second cooling loop. The first cooling loop can include a first heat exchanger for transferring heat from the load to a first cooling fluid, a second heat exchanger for transferring heat from the first cooling fluid to a second cooling fluid, and a flow control valve for controlling flow of the first cooling fluid through the first cooling loop. The controller can monitor a parameter and/or operate the flow control valve to maintain a temperature associated with the load. The controller can selectively boost a cooling capacity of the first cooling loop when a change in the parameter exceeds a threshold.

The present disclosure relates to the field of power supply and an uninterruptible power supply is disclosed. The uninterruptible power supply includes a first power board, a liquid cooling plate, a second power board, a first set of power devices arranged on the first power board, and a second set of power devices arranged on the second power board; the liquid cooling plate is stacked between the first power board and the second power board, and is configured to dissipate heat from the first set of power devices and the second set of power devices; the liquid cooling plate comprises an inlet, an outlet, and a cooling passage communicating the inlet and the outlet, and the cooling passage is configured to accommodate a coolant; and the first set of power devices and/or the second set of power devices includes a temperature-sensitive component and multiple power components, and the multiple power components are located in front of the temperature-sensitive component along a flow direction of the coolant in the cooling passage. In the present disclosure, heat dissipation for the temperature-sensitive component with higher temperature sensitivity is prioritized to ensure a service life of the uninterruptible power supply, and then heat dissipation of other power components is performed, so that liquid cooling for all power components is suitably considered.

A shelf may include a top surface. The shelf may include a set of retain tabs configured to couple a set of battery modules. The shelf may include a set of alignment tabs configured to align one or more battery modules of the set of battery modules as the one or more battery modules are translated from a non-secured position to a secured position.
