Abstract: Control systems for a multi-level diode-clamped inverter and corresponding methods include a processor and a digital logic circuit forming a hybrid controller. The processor identifies sector and region locations based on a sampled reference voltage vector V* and angle Θe*. The processor then selects predefined switching sequences and pre-calculated turn-on time values based on the identified sector and region locations. The digital logic circuit generates PWM switching signals for driving power transistors of a multi-level diode-clamped inverter based on the turn-on time values and the selected switching sequences. The control system takes care of the existing capacitor voltage balancing issues of multi-level diode-clamped inverters while supplying both active and reactive power to an IT load. Using the control system, one can generate a symmetrical PWM signal that fully covers the linear under-modulation region.

Abstract: The cooling systems of the present disclosure include a first refrigerant circuit in thermal communication with a heat load and in fluid communication with a main condenser, a free cooling circuit in fluid communication with the main condenser and a free-cooled water source, a chilled water circuit in fluid communication with the main condenser and an evaporator, and a second refrigerant circuit in fluid communication with the evaporator and a secondary condenser. The free cooling circuit is in thermal communication with the first refrigerant circuit via the main condenser, the chilled water circuit is in thermal communication with the first refrigerant circuit via the main condenser, and the second refrigeration circuit is in thermal communication with the chilled water circuit and the free cooling circuit. The second refrigeration circuit cools a fluid flowing in the chilled water circuit. Methods of operating a cooling system are also disclosed.

Abstract: Modular air cooling and distribution systems include a fan and heat exchanger cooling assembly and a controller which controls the fan speed based on temperature and velocity measurements. The cooling assembly includes a fluid-to-air heat exchanger and a variable speed fan. The fluid in the fluid-to-air heat exchanger may be propylene glycol or water. The heat exchanger minimizes pressure drop and maximizes heat transfer. The quantity of cooling assemblies is selected to match the indoor cooling requirements. The cooling assemblies are easily assembled together, stacked vertically, and/or connected horizontally, to match the cooling load. If additional cooling capacity is needed in the future, more cooling assemblies can easily be added, and the cooling assemblies may be expanded vertically and/or horizontally. The speed of the fans of the fan and heat exchanger assemblies are controlled based on fluid temperature and fluid velocity measurements, which may be obtained by an anemometer.

Abstract: A power supply system includes an energy storage device electrically connected to a power grid, a power distribution assembly electrically connected to a load, and a power generation device electrically connected to the power distribution assembly. The energy storage device and the power grid are configured to supply electric power having a first voltage range to the power distribution assembly, which in turn, is configured to supply electric power having a second voltage range less than the first voltage range to the load. The energy storage device and the power generation device each are configured to at least temporarily supply a flow of electric power to the power distribution assembly when electric power from the power grid is interrupted such that a substantially uninterrupted flow of electric power is supplied to the load.

Abstract: The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

Abstract: A modular server rack cooling structure for cooling at least one server in at least one server rack of a data center assembly includes at least a first supporting member and at least a first heat exchanger. The first heat exchanger is coupled to the first supporting member, which is configured to position the first heat exchanger in heat transfer relationship with the at least one server. The first heat exchanger is not attached to the at least one server rack. The modular server rack cooling structure is also applied to a system that includes at least a first rack and at least a second rack disposed opposite from one another to form a hot aisle or a cold aisle. A method is disclosed for installing additional heat exchangers on the support structure of a modular server rack cooling structure to meet increased cooling capacity requirements without requiring additional space.
