Abstract: A power supply apparatus includes a first power module, a second power module, an energy storage module, and a controller. An output terminal of the first power module is connected in parallel to an output terminal of the second power module, which is then connected to a load, and load dynamic response performance of the second power module is better than load dynamic response performance of the first power module. The energy storage module is connected to the output terminal of the first power module and connected between a midpoint of the load and a reference ground. The energy storage module is configured to store electric energy and supply power to the load. The controller is configured to, in response to the load being in a dynamic change status, control the second power module to supply power to the energy storage module.

Abstract: The power supply system includes a first voltage conversion unit, where the first voltage conversion unit is an isolated voltage conversion unit, and the first voltage conversion unit is connected to a power supply, and is configured to convert a voltage of the power supply into a power supply voltage of the service board, that is, a first voltage; and a second voltage conversion unit, where the second voltage conversion unit is a non-isolated voltage conversion unit, the second voltage conversion unit is deployed on the service board, and the second voltage conversion unit is configured to convert the first voltage into a power supply voltage of a first load module on the service board, that is, a second voltage.

Abstract: A wireless communication system configured for the efficient allocation of resources is provided. The wireless communication system can include a transmit system having a first set of one or more antennas each configured to transmit a data signal over a region to a receive system having a second set of two or more antennas each configured to receive the transmitted data signal. The transmit system can be configured to adjust a transmission parameter of a data signal based on a level of signal fading in the region to sustain a target bit rate, adjust a power and a bit rate at which a data signal is transmitted based on the level of signal fading in the region and select a subset of antennas within the first set of antennas to be used to transmit a data signal based on the level of signal fading in the region.
