摘要： Examples described herein relate to a power management system. The power management system may include an input power filter coupled between a common power bus having a first voltage level and a load. The input power filter may include a variable impedance circuit coupled to an input capacitor. Further, the power management system may include a bus voltage controller coupled to the input power filter to detect a transient event causing a surge in a load current drawn by the load and to alter an impedance of the variable impedance circuit to limit an input current flowing via the variable impedance circuit, thereby maintaining voltage on the common power bus within a predefined range from the first voltage level.

摘要： A method, system, and device for using an interface controller to validate and authenticate controller code for a commodity device to be included within a computer system (e.g., a power supply) are provided. In one example, a commodity device controller includes dynamic memory for control software (e.g., control code to control operation of the commodity device) that may be validated (and/or updated) using an interface controller. The interface controller may perform this update/validation at startup (or run-time) to ensure secure control over aspects of the computer device including the commodity device control code. If a security risk is detected it may be mitigated in various ways, including disabling of the commodity device. Control code provided by third-parties (e,g., supplier of commodity device) may be validated and secured using disclosed techniques.

摘要： A power supply may include a power input to connect to a power source to receive an input power for the power supply, a bulk capacitor operatively connected to the power input, and a threshold manager having a processor operatively connected to the power input and the bulk capacitor. The threshold manager to monitor the input power, calculate a threshold to perform a shutdown operation based on a shutdown requirement provided by a computing device, and in response to a power loss of the input power, monitor a bulk voltage of the bulk capacitor and send an alert to the computing device to perform the shutdown operation when the bulk voltage meets the threshold.

摘要： Example implementations relate to a variable soft start device. For example, in an implementation, the variable soft start device may set the capacitance of a variable capacitance circuit connected to a soft start pin of the electronic fuse. The variable soft start device may read a power-good signal from the electronic fuse and determine the capacitance to set according to the power-good signal.

摘要： Various examples provide systems and methods in which a capacitor is charged by an active first power factor correction module and a voltage across the capacitor is determined while the second power factor correction module is exclusively active. A health state of the second power factor correction module may be determined based on the determined voltage across the capacitor.

摘要： Examples disclose a power system comprising a first power supply to provide a first power to a load. Further, the power system comprises a second power supply to detect a droop in the first power to the load, the droop associated with a decrease in efficiency of the first power supply. Additionally, the second power supply is to balance the load based on the droop detection by providing a second power in addition to the first power to the load to increase the efficiency of the power system.

摘要： Example implementations relate to determining computing device information. In some examples, a controller may comprise a processing resource and a memory resource storing machine-readable instructions to receive a waveform corresponding to an input current that includes a non-cyclical irregular waveform modification from a power supply of a computing device, analyze the modified waveform of the input current to determine a binary message included in the modified waveform, and determine, based on the binary message, information about the computing device.
