An interleaved boost converter 100, comprising a switching circuit 102 with two switching arms 122 and 124, each including at least two switches and an inductor. A load detection module 104 determines the electrical load, while sensors 106 monitor the temperature and operational time of the switches. A control unit 108 is configured to activate both switching arms 122 and 124 upon boot-up and deactivate one switching arm when the electrical load falls below a predefined percentage of total capacity. The control unit 108 alternates operation between the switching arms 122 and 124 if the temperature or operational time of switches in one arm exceeds predefined thresholds, reducing thermal stress and enhancing efficiency. When the electrical load exceeds the predefined percentage, both switching arms 122 and 124 are reactivated. Adaptive phase control optimizes efficiency, minimizes losses, reduces thermal stress, and improves reliability by dynamically adjusting operational phases.

The present disclosure relates to a spacer for circuit breaker. The spacer 300 for a circuit breaker, comprising a cuboidal enclosure having a plurality of surfaces 301, 302, 303, 304, 305, 306 forming a space for mounting over a top of the circuit breaker with one or more adjacent circuit breakers. The plurality of surfaces includes a first surface 301 having a plurality of cutouts for dissipation of heat from the circuit breaker, a second surface 302 having an open slot for allowing connection of wires. Further, a third open surface 303 and a fourth open surface 304 is provided which forms the space within the enclosure for mounting over the top of the circuit breaker. Further, a fifth surface 305 and a sixth surface 306 is provided which are opposite to each other and having a thickness to provide an air gap with the one or more adjacent circuit breakers.

A power distribution unit may include an input power connector configured to receive input electrical power from an external power source. The power distribution unit may include a primary busbar configured to receive the input electrical power from the input power connector and distribute the input electrical power via a power configuration. The power distribution unit may include an output controller assembly configured to receive distributed input electrical power from the primary busbar and manage the distributed input electrical power. A power distribution unit may include a plurality of receptacles configured to receive the distributed input electrical power from the output controller assembly, wherein power to one or more of the plurality of receptacles is based on the power configuration.

A heat pump system may include a remote condenser arranged in an outdoor unit. The heat pump system may include a flooded condenser arranged in an indoor unit, where the remote condenser is coupled to the flooded condenser via a remote condenser port. The heat pump system may include a refrigerant pump configured to move a refrigerant from the remote condenser to the flooded condenser. The heat pump system may include a segregation valve configured to segregate the remote condenser when not in use. The heat pump system may further include a compressor, an evaporator, and an expansion valve.

A modular data center infrastructure system can include one or more through modules and one or more end modules. The modules can be disposed above one or more cabinets, such as computer equipment cabinets. The modules can be disposed above an aisle between two rows of cabinets and/or coupled to opposing pairs of cabinets. The modules can be coupled to one another. The system can include a first through module coupled above a first opposing pair of the cabinets, a second through module coupled to the first through module and/or above a second opposing pair of the cabinets, and an end module coupled to one of the through modules and/or above a third opposing pair of the cabinets.

A system and method for continuous real-time monitoring of a primary chiller device of a pumped two-phase chiller system includes flow rate and outlet temperature sensors within the primary chiller device, continually sensing a flow rate and outlet temperature of a primary fluid refrigerant leaving the primary chiller device to circulate through a pumping unit and transfer heat absorbed from downstream IT devices (and, with respect to direct-to-chip (D2C) systems, downstream chip assemblies). The pumping unit controller receives the collected flow rate and outlet temperature data and, when the flow rate and/or outlet temperature deviates from acceptable ranges, e.g., too low a flow rate, too high an outlet temperature, detects an imminent failure of the primary chiller device and responds accordingly, e.g., requesting shutdown of the primary chiller device or the downstream IT devices.

Systems and methods for providing consistent and reliable thermal insulation for electrical components that are proximate to a transformer within an overall data center environment that is executing high-power and variable high-performance computing (HPC) and/or artificial intelligence (AI) workloads are disclosed. By installing a conductor pass-through device that both enables electrical cables to connect to the transformer via channels in the device and also provides thermal insulation against excess heat being emitted from the transformer, the other electrical components stay within their normal operating temperature ranges and do no overheat.

A power distribution panel can include a cabinet having a top and a bottom, one or more breakers at least partially disposed within the cabinet, and one or more busbars at least partially disposed within the cabinet. The top of the cabinet can include one or more top cable entries and the bottom of the cabinet can include one or more bottom cable entries. The busbars can selectively receive cables from the top cable entries and/or the bottom cable entries. The power distribution panel can be configured and/or reconfigured for top entry or bottom entry.

An outside cabinet assembly is disclosed. A cavity is formed under ground. An enclosure is received in the cavity. An equipment cabinet is received within the enclosure and configured to house electronic components. An environmental control unit (ECU) is thermally coupled to the equipment cabinet. A utility fluid conveyance (UFC) is disposed outside the enclosure. A thermal transfer system (TTS) is in fluid or thermal communication with the ECU and extending from the enclosure to the UFC disposed outside the enclosure. The TTS may include a heat-conductive conduit thermally coupled to the UFC through a thermal interface material so as to exchange heat with fluid transported by the UFC to regulate an internal temperature of the equipment cabinet while the equipment cabinet remains under the ground.

A cooling system can include a cooling loop, a targeted cooling path, a valve for controlling the flow of a first cooling fluid through the targeted cooling path, and a controller for operating the valve. The cooling loop can include a first heat exchanger for transferring heat from a first heat load to the first cooling fluid, a second heat exchanger for rejecting heat from the first cooling fluid, and a prime mover for circulating the first cooling fluid through the cooling loop. The targeted cooling path can include a third heat exchanger for transferring heat from a second heat load to the first cooling fluid.
