Abstract: This application provides a photovoltaic power optimizer and a method and apparatus for controlling same, and a photovoltaic power generation system. The photovoltaic power optimizer includes: a power optimization module, a bypass module, and a control module, where the bypass module is connected to an input end of the power optimization module, an output end of the power optimization module, and the control module, and the control module is connected to the power optimization module; and when detecting that the power optimization module is faulty, the control module is configured to control the bypass module to be on, to bypass the faulty power optimization module, so that the photovoltaic battery component can be directly connected to other battery groups in the photovoltaic power generation system, and connected to an inverter.

Abstract: A memory access technology and a computer system, where the computer system includes a memory controller and a medium controller connected to the memory controller. In the computer system, when detecting that an error occurs in first data that is returned by the medium controller in response to a first send command, the memory controller determines sequence information of the first send command in a plurality of send commands that have been sent by the memory controller within a time period from a time point at which the first send command is sent to a current time, and sends a data retransmission command to the medium controller to instruct the medium controller to resend the first data based on the sequence information.
