Abstract: A transfer switch for hybrid switching between a first power source and a second power source, the transfer switch includes a first switch and a second switch, the first and second switch connecting a load to a first power source and a second power source, respectively. The first switch includes at least one first solid state switching device (SSSD) pair. The second switch includes at least one second SSSD pair. The at least one first SSSD pair includes a different type of switching devices relative to the type of switching devices of the at least one second SSSD pair. Moreover, a controller may be configured to selectively cycle the at least one first SSSD pair and the at least one second SSSD pair on and off to electrically couple one of the first power source and the second power source to the load.

Abstract: Technologies for interactive predictive control of uninterruptible power supply systems are disclosed. In an illustrative embodiment, a method of controlling a double-conversion uninterruptible power supply (UPS) system may include defining, with a digital signal processor (DSP), a curve as a function of a plurality of user-input reference points associated with an inductor coupled to either an input or an output of the double-conversion UPS system, where the curve is indicative of an electromagnetic behavior of the inductor. The method may also include determining, with the DSP, in response to an application of current to the inductor, an inductance value for the inductor based on the defined curve and the applied current. The method may further include setting, with the DSP, as a function of the determined inductance value, a duty cycle to control switching of at least one of an active rectifier and an inverter of the double-conversion UPS system.

Abstract: Systems and methods for reducing inrush current to energize a transformer from a first power source or second power source using a transfer switch device including monitoring input phase voltage at a first and second switching pair, sending a first set of gate signals to the first switching pair and second set of gate signals to the second switching pair to selectively couple the transformer to the first power source or second power source, and operating the first switching pair and second switching pair in a normal operating mode at a next cycle once transformer flux reaches a saturation point. The transfer switch device includes a first switch and second switch connected to the first power source and second power source, respectively, and each switch including the first switching pair and second switching pair connected in a reverse orientation to enable a bi-directional flow of current at each phase.

Abstract: A method of operating a static transfer switch is provided. The method includes monitoring a voltage waveform for each phase of first and second power sources, and calculating flux for each phase of the power sources. The method also includes determining (i) a first flux difference between the respective flux of the first phases of the first and second power sources, (ii) a second flux difference between the respective flux of the second phases of the first and second power sources, and (iii) a third flux difference between the respective flux of the third phases of the first and second power sources. The method further includes turning off a third solid-state switch to disconnect the third phase of the first power source from a load, in response to the controller determining that the third flux difference is greater the first and second flux differences.

Abstract: Technologies for transferring a load by a static transfer switch (STS) to a catcher uninterruptible power supply (UPS) are disclosed. In an illustrative embodiment, each STS in a catcher UPS system monitors an available power of the catcher UPS. The STS determines, in response to a power failure event of an associated UPS, whether a real-time power supplied to a load connected to the STS exceeds the available power of the catcher UPS and whether the STS has priority over each other STS in the system. The STS transfers the load from the associated UPS to the catcher UPS in response to determining that the real-time power supplied to the load does not exceed the available power of the catcher UPS and that the STS has priority over each other STS in the system.

Abstract: In one aspect, a controller for managing electrical faults in a microgrid is provided. The microgrid includes electrical loads, electrical sources, and circuit protection devices that selectively couple the electrical loads and the electrical sources with each other. The controller comprises at least one processor configured to direct a grid tie switch to open to electrically isolate the microgrid from an electric grid, determine, in response to directing the grid tie switch to open, that an electrical fault exits in the microgrid, and determine whether a fault current of the electrical fault is less than a threshold value. The at least one processor is further configured to direct the grid tie switch to close to electrically connect the microgrid to the electric grid and increase the fault current above the threshold value in response to determining that the fault current is less than the threshold value.
