Abstract: A method includes generating a turbo mode operation instruction based on a plurality of operating conditions, based on the turbo mode operation instruction, adjusting a system limit of a power supply so as to provide excess power to a load coupled to the power supply, detecting at least one operating parameter to obtain a detected operating parameter, determining whether the detected operating parameter exceeds a predetermined threshold, and reducing the system limit of the power supply so that the detected operating parameter drops below the predetermined threshold.

Abstract: A dual-input power supply has two power paths that connect a server in a data center to electrical power. Each power path has a first stage that comprises a power-factor correction circuit. The power paths share a common second stage that comprises a dc/dc converter. The first stages of the power paths collectively define a pair of first stages that is disposed either within a package that is off the motherboard or without a package and on the motherboard. Similarly, the second stage is disposed either within a package that is off the motherboard or without a package and on the motherboard.

Abstract: An apparatus includes a case, a first printed circuit board (PCB) and a second PCB within the case. The case includes a top portion and a bottom portion opposite to each other. The first PCB has a first surface and a second surface opposite to each other, and is attached to the top portion of the case via the second surface of the first PCB. At least one heat-generating device is mounted on the first surface of the first PCB. The second PCB has a first surface and a second surface opposite to each other, and is attached to the bottom portion of the case via the second surface of the second PCB. At least one heat-generating device is mounted on the first surface of the second PCB. The apparatus may include more PCBs. An inner shell may be provided forming an air duct within the case.

Abstract: An apparatus includes, on a top layer of a circuit board, a first and a second synchronous rectifier groups (SRGs) placed along first two opposite sides of a first phase of a transformer including three phases. A second and a fourth SRGs are placed along the first two opposite sides on a bottom layer of the circuit board. The first and second SRGs are connected between a first terminal of the first phase and a grounding terminal. The third and fourth SRGs are connected between a second terminal of the first phase and the grounding terminal. Two filter capacitor groups are placed along second two opposite sides of the first phase on the top layer. Another two filter capacitor groups are placed along the second two opposite sides on the bottom layer. The four filter capacitor groups are connected to a third terminal of the first phase.
