Patent number: 12470148Abstract: 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.Type: GrantFiled: October 6, 2022Date of Patent: November 11, 2025Assignee: Google LLCInventors: Shuai Jiang, Xin Li, Woon-Seong Kwon, Cheng Chung Yang, Qiong Wang, Nam Hoon Kim, Mikhail Popovich, Houle Gan, Chenhao Nan

Patent number: 12334245Abstract: 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.Type: GrantFiled: August 8, 2024Date of Patent: June 17, 2025Assignee: Google LLCInventors: Chenhao Nan, Houle Gan, Runruo Chen, Qiong Wang, Xin Li

Patent number: 12242326Abstract: 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.Type: GrantFiled: August 24, 2022Date of Patent: March 4, 2025Assignee: Google LLCInventors: Xiong Li, Xin Li, Qiong Wang, Kaushik Vaidyanathan, Chenhao Nan, Robert Ashby Armistead, III

Publication number: 20240396447Abstract: 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.Type: ApplicationFiled: May 22, 2023Publication date: November 28, 2024Inventors: Shuai Jiang, Chenhao Nan, Houle Gan, Qiong Wang

Each unregulated voltage converter includes a switched block producing an output voltage across its output terminals. The power supply includes a voltage supply input coupled to at least one of the unregulated voltage converters, and an unregulated voltage bus coupled to at least one of the unregulated voltage converters. The power supply includes a voltage regulator coupled to the unregulated voltage bus and producing a regulated voltage across its output terminals. The output terminals of the voltage regulator are connected in parallel to the output terminals of at least one of the unregulated voltage converters. This can produce a regulated output voltage across a pair of power supply output terminals.Type: GrantFiled: August 16, 2017Date of Patent: May 8, 2018Assignee: Google LLCInventors: Shuai Jiang, Chenhao Nan, Xin Li, Chee Chung, Mobashar Yazdani
