Abstract: Various embodiments of the present technology provide methods for boosting a voltage differential of an energy storage by using a boost component, determining a server system being switched to a boost mode, and discharging the energy storage to provide additional power supplies to the server system during the boost mode. In some embodiments, processing demands of a server system can be monitored. In response to determining that a boost mode is needed to support processing demands of the server system or detecting a component being a bottleneck in processing pipelines of the server system, a boost activation signal can be generated. The boost activation signal can cause a CPU, the bottleneck component, or another component of the server system to operate under a higher clock speed such that a higher processing capacity can be achieved.

Abstract: The present disclosure provides a system and method for dynamically defining a specific input pin of a management controller (e.g., a baseboard management controller (BMC)) of a server system in response to a new device being plugged into the server system. The new device comprises one of a power supply unit (PSU), an automatic transfer switch (ATS), or a battery backup unit (BBU) of the server system. In some implementations, the PSU, the ATS, and the BBU are modularized into a plurality of ATS modules, a plurality of PSU modules, and a plurality of BBU modules, respectively. Each of the plurality of ATS modules, the plurality of PSU modules, and the plurality of BBU modules has substantially the same physical size.

Abstract: A system and method for current balancing from a three-phase AC power source is disclosed. The system includes power supply units, each having inputs coupled to one output of the three phase power source, and a neutral conductor. Multiple loads are each coupled to a DC output of one of the power supply units. Each of the loads include a component having adjustable power consumption. A controller is coupled to each of the power supply units and each of the loads. The controller is operable to compare the power consumption of each of the loads to an average value. The controller adjusts the power consumption of at least one of the loads to balance the power consumption between the loads.

Abstract: A power supply unit that allows measurement of the capacitance without interrupting operation of the unit is disclosed. The unit includes a controller that causes a voltage change of a capacitor from a first threshold voltage between two periods of time. The time difference of when the voltage reaches a second threshold voltage is measured and the capacitance is determined from the time measurement, voltage change and power dissipation. The determination of capacitance may be performed while the power supply unit is actively supplying power.

Abstract: Various examples of the present disclosure provide a high efficient battery backup (BBU) system and systems and methods for managing the BBU system through a microcontroller unit (MCU) and an ORing FET system of the BBU system. In some examples, a baseboard management controller (BMC) of a server system is used to control the MCU and the ORing FET system of the BBU system such that the BBU system can operate in multiple operating modes without a battery discharger. The operating modes of the BBU system includes, but are not limited to, a battery constant-current-charging mode, a battery constant-voltage-charging mode, a battery discharging mode, or a battery capacity calibration mode.

Abstract: The present disclosure provides a system and method enabling a self-burn-in test for a power supply device (PSD) of a server system using a multi-phase scheme. The PSD comprises a power-width modulation (PWM) controller, and a plurality of power stages. Each of the plurality of power stages comprises a driver, a high-side MOSFET, and a low-side MOSFET. In one aspect of the present disclosure, upon receiving a test mode command from a controller of the server system, the PWM controller can send a PWM signal to switch a specific power stage to the On state, and send at least another PWM signal that switches other power stage(s) of the plurality of power stages to the Tri-state. During a subsequent self-burn-in test of the specific power stage, low-side MOSFET(s) of the other power stage(s) can function as a load for the specific power stage.
