Abstract: An intelligent static transfer switch provides a primary voltage source to a destination facility via a primary power supply, monitoring the voltage level associated with the primary power supply. When the primary voltage drops below a threshold level (e.g., conditions normally associated with a transfer to a backup power supply), the switch samples the waveform of the primary voltage and compares the sampled waveform to reference waveforms stored to memory, each reference waveform corresponding to an order to allow or inhibit the transfer to backup power. When the sampled waveform matches a reference waveform, the switch carries out the corresponding order (allow or inhibit). When there is no match, the switch allows transfer to backup power but continues to monitor the sampled waveform to determine whether the transfer should have been allowed or inhibited. The sampled waveform is added as a reference waveform with the appropriate allow or inhibit order.

Abstract: Systems and methods for providing consistent and reliable power to a data center that is executing high-power and variable high-performance computing (HPC) and artificial intelligence (AI) workloads are disclosed. By installing a three-phase current sensor at or near the data center, or along the power grid before the power arrives at a power conversion system (PCS), the power conversion system is configured to response faster to changing and variable workloads that ramp up and down both quickly and inconsistently. A controller within the PCS is then configured to customize the amount of power that is sent to the data center coming from converted power from the grid, and from a battery energy storage system.

The component may include one or more DC/DC converter circuits configured to receive one or more second input powers from one or more second power sources and convert the one or more second input powers into one or more second DC powers. The component may include a DC link configured to receive the first DC power and the one or more second DC power, wherein the DC link merges an output of the first DC source and output of the one or more second DC sources to produce a final DC power.

Abstract: A system and method for multi-distribution load management control includes a controller for managing power distribution from a utility alternating-current (AC) source and at least one rapid-recharge direct-current (DC) storage device. The controller detects a load change event, e.g., load step or load drop associated with periodic fluctuation or cycling of high rate of change loads between peak and minimum power levels. Based on rate of change of the load change event, an average load power is determined. The controller maintains the average load power drawn from the utility source by supplying the high rate of change loads from the utility source and DC storage device in proportion. During minimum power cycles associated with the high rate of change loads, the average load power is maintained and power diverted in proportion to the DC storage device for recharging in preparation for the next peak power cycle.
