Abstract: A voltage regulator having a multiple of main stages and at least one accelerated voltage regulator (AVR) bridge is provided. The main stages may respond to low frequency current transients and provide DC output voltage regulation. The AVR bridges are switched much faster than the main stages and respond to high frequency current transients without regulating the DC output voltage. The AVR bridge frequency response range can overlap with the main stage frequency response range, and the lowest frequency to which the AVR bridges respond may be set lower than the highest frequency to which the main stages respond.

Abstract: Controlling voltage supplied to a load includes predicting a load current transient, generating a turbo signal in response to predicting the load current transient, and increasing, in response to the turbo signal, responsiveness of a voltage regulator supplying voltage to the load.

Abstract: Methods, systems, and apparatus, for powering AC and DC loads in the event of a power failure. In one aspect, a system includes one or more DC loads that are powered by DC power, one or more AC loads that are powered by AC power, and an uninterruptible power supply (UPS). The UPS includes AC terminals connected to an AC power source and to the one or more AC loads to power the AC loads, DC terminals connected to a backup battery and to the one or more DC loads to power the DC loads a bidirectional AC/DC converter connected between the AC terminals and the DC terminals, and a controller that selectively switches the bidirectional AC/DC converter to the first mode when the AC power source is available and to the second mode when the AC power source is not available.

CPC classification number: G06F1/3296
Abstract: The technology is generally directed to a coordinated power throttling mechanism for a payload using power provided by a rack such that the rack power does not exceed a threshold amount for greater than a predetermined period of time. The coordinated power throttling mechanism includes the rack providing a power throttling signal to the payload and the payload executing the power throttling upon detection of the throttling signal. The payload may detect the throttling signal and, after a delay, execute the power throttling. The delay may ensure that all payloads within the rack have detected the power throttling signal.

Abstract: The subject matter described herein provides systems and techniques for the integration of TLVR technology in a vertical power VR module. A multiple-secondary TLVR topology using a controlled leakage inductance in the place of a separate compensation inductor, Lc, may be employed for the vertical power VR module. In addition, the capacitance inside the device to which the TLVR based vertical power VR module supplies power, rather than an output capacitance board, may be used in order to allow the module to be a single layer. Example structures that may include one or more primary windings and/or one or more secondary windings for each of possibly multiple linked phases of the TLVR based module are provided. The windings may be formed using traditional copper windings or printed circuit board (PCB) copper trace winding.

Abstract: The subject matter described herein provides systems and techniques for the integration of Trans-Induction Voltage regulator (TLVR) technology in a vertical power Voltage Regulator (VR) module. The capacitance inside the device to which the TLVR based vertical power VR module supplies power, rather than an output capacitance board, may be used in order to allow the module to be a single layer. In some instances, output capacitors may be integrated into components of the structures to provide adequate operational capacitance previously provided by the output capacitance board. Example structures may also include a controller.
