Abstract: This application relates to a converter in a photovoltaic power generation system and a converter control method. An input end of the converter is connected to at least one photovoltaic module, and an output end is connected to an inverter. The control method includes: determining an output power-voltage (PV) curve of a converter based on an output PV curve of the photovoltaic module; and controlling a voltage output of the converter based on the output PV curve of the converter. The output PV curve includes at least a simulated voltage limiting section and a constant power section that are connected. In this application, an existing MPPT control policy of the inverter can be adapted when a voltage-limited output is implemented, to avoid a case in which a power of a photovoltaic string drops to zero.

Abstract: The present disclosure provides a display control method and apparatus for a game screen, a storage medium, and an electronic device, and the method comprises: providing a first touch control region on the graphical user interface, and configuring the virtual character to perform at least one of displacement and rotation in the game scene according to a first touch operation received by the first touch control region; providing a second touch control region on the graphical user interface, and when a second touch operation in the second touch control region is detected, changing the presented visual field of the game scene on the graphical user interface; when an end of the second touch operation is detected, controlling the presented visual field of the game scene on the graphical user interface to be restored to a state before the second touch operation.
