Abstract: An extension kit for an IT equipment cabinet is disclosed. The extension kit has two vertical profiles, two transverse profiles and four depth profiles. The two vertical profiles and the two transverse profiles form a rectangular frame, wherein each depth profile is fastened to the frame with one of its ends. In addition, two adapter profiles are provided, which are arranged parallel to the vertical profiles on the other ends of the depth profiles. These are designed to be fastened to an IT equipment cabinet to extend a depth of the cabinet without affecting its height or width.

Abstract: A cooling device having a vaporizer for vaporizing a working liquid, wherein the working liquid is held on a vaporizer bottom; a compressor for compressing a vaporized working liquid, wherein the compressor is configured to convey the vaporized working liquid from the bottom to the top in a setup direction; a liquefier having an upper wall configured such that the vaporized and compressed working liquid is condensable at the upper wall and drips down from top to bottom; and an intermediate bottom configured to collect a dripped-down working liquid, wherein the intermediate bottom comprises at least one opening through which the dripped-down working liquid may reach the vaporizer bottom.

Abstract: An electric motor includes: a rotor with a first number of permanent magnets, wherein each permanent magnet encompasses a first circular sector; a stator with a second number of pole feet, wherein a first group of coils is electrically connected via a first star point, wherein a second group of coils is electrically connected via a second star point to be conductive, wherein the second star point is electrically insulated from the first star point, wherein a coil of the first group of coils is arranged between two coils of the second group of coils; and a controller for applying drive signals to the first group of coils so as to provide the rotor with a torque with respect to the stator, and for applying a control signal that differs from the drive signals to at least one coil of the second group of coils.

Abstract: A plate for a heat exchanger, which comprises a plurality of unit cells, each one of the unit cells comprising a first face and a second face which is opposite the first face, the first face and the second face having a plurality of spacers which are arranged so as to produce mutually perpendicular directions of flow between the first face and the second face. The spacers differ between the first face and the second face in terms of number and/or shape and/or size.

Abstract: The present disclosure relates to method for use with a system having first and second uninterruptible power supplies (UPS 1 and UPS 2), and where the two UPSs are connected across a DC+ and a DC? terminal of a common battery, and where a neutral imbalance between neutral lines of the two UPSs has been corrected, giving rise to a current flow from a DC? bus of one of the UPSs to a DC? bus of the other one of the UPSs. The method corrects for a nominal DC reference voltage for one of the UPSs to eliminate the current flow to the DC? bus of the other UPS.

Abstract: A method of controlling an uninterruptible power supply system to increase component life includes decreasing a maximum output power limit of the uninterruptible power supply system when a temperature that the uninterruptible power supply system is experiencing has increased and increasing the maximum output power limit when this temperature has decreased. In an aspect, this temperature is ambient temperature of an equipment enclosure of the uninterruptible power supply system in which at least a rectifier and inverter of the uninterruptible power supply system are located. In an aspect, the method further includes upon the system going into an overload condition, determining an overload time limit based upon the temperature, the overload condition and an initial load condition. In an aspect, the method further includes upon the system going into a back-up power mode, determining a battery autonomy based upon the temperature.

Abstract: A method is provided for communicating data amongst controllers in a power supply system. The method include receiving a present measure of a parameter indicative of an operating state of an uninterruptible power supply (UPS); comparing the present measure to a control window for the parameter, where the control window defines a minimum value for the parameter and a maximum value for the parameter; updating the control window based on the present measure when the present measure falls outside of the control window; and transmitting the present measure via a controller area network to a managing controller when the present measure falls outside of the control window.

Abstract: An uninterruptible power supply system has a three-level T-Type inverter A method that improves clearing a short of a load coupled to an output of the inverter when the load experiences a short circuit event includes commutating with a controller each phase of the inverter in a two level mode current generation when output voltage and output current of that phase have the same direction and commutating each phase of the inverter in a three level mode current generation when the output voltage and output current of that phase have opposite directions.
