Abstract: Communicating with verified data includes receiving a request with a first device where the request is addressed to a register within the first device and sending a response with the first device to a second device where the response includes an address of the register.

Abstract: Examples disclose a controller with a meter interface to receive a first input power measurement provided from a meter. The meter delivers input power to a rectifier which delivers power to a load. Additionally, the examples disclose the controller with a rectifier interface to receive a second input power measurement provided from the rectifier. Further, the examples disclose the controller to manage the rectifier based on the first and the second input power measurements.

Abstract: A method for balancing input current with at least two parallel power supplies, including the steps of defining an input current difference tolerance, measuring input current from the at least two parallel power supplies, calculating an absolute value of the difference between the two measured input currents, and when the calculated value exceeds the tolerance, performing the subset of steps including employing an adjustment technique to calculate new operating parameters for the two power supplies, configuring the two power supplies with the new operating parameters, and repeating the steps above except for the defining step.

Abstract: Method and system for load sharing in a multiple power supply system. At least some of the illustrative embodiments are power supply units including a switching circuit, a coarse adjustment circuit coupled to the switching circuit (the coarse adjustment circuit configured to send an internal command to the switching circuit to modify a pulse width modulated signal that controls output current of the power supply unit), and a communication port coupled to the switching circuit. The power supply unit configured to receive from an external device over the communication port an external command to modify the pulse width modulated signal of the switching circuit. The power supply unit is also configured to modify the output current, the amount of modification based on the external command, and the internal command from the coarse adjustment circuit.

Abstract: Communicating with verified data includes receiving a request with a first device where the request is addressed to a register within the first device and sending a response with the first device to a second device where the response includes an address of the register.

Abstract: A method for power capping is disclosed. The power supplied to a load from a power supply is compared to a power capping limit 302. When the power drawn by the load exceeds the power capping limit, power to the load is supplied by both the power supply and an energy storage device 304.

Abstract: A system and method are provided for supplying power to a load using deep-sleep-mode power supplies. Each of plural switching power supplies includes an input converter, an output converter and a standby converter. Each is configured to have its output converter connected to the load, and each is configured to operate in at least an online mode in which the input, output and standby converters are enabled for switching, and a deep sleep mode in which the input, output and standby converters are disabled from switching. A system controller is configured to place a first set of the plural switching power supplies in the online mode and a second set of the plural switching power supplies in the deep sleep mode while the load is operating and the power supplies in the first set are supplying power to the load.

Abstract: Systems and methods of an adaptive rating for a backup power supply are disclosed. An exemplary method includes measuring electrical output for a load. The method also includes determining an adaptive rating for at least one battery module of a backup power supply. The method also includes storing changing adaptive ratings for the at least one battery module over time based on the measured electrical output for the load.
