摘要： A memory management method, apparatus, and system are provided. The memory management method is performed by a memory management hardware accelerator, and the memory management hardware accelerator is coupled to an application subsystem (501) and a communications subsystem (503). The application subsystem (501) is configured to run a main operating system, and the communications subsystem (503) is configured to run a communications operating system. The method includes: obtaining a set of memory addresses corresponding to dynamic memory space allocated by the main operating system to the communications subsystem (S001), where the set of memory addresses includes one or more memory addresses; and sending some memory addresses in the set of memory addresses to a component of the communications subsystem (S002).

摘要： This application provides a method for managing a charging pile system (100) and the charging pile system (100). The method includes: When a first charging terminal (51) in a plurality of charging terminals (50) is connected to a first to-be-charged device (61), a power scheduling module (30) determines first needed power transmitted by a first DC/DC module (41) correspondingly connected to the first charging terminal (51), where the first needed power is needed power of the first to-be-charged device (61); the power scheduling module (30) determines total surplus power transmitted by all AC/DC modules (10), where the total surplus power is a difference between total rated power of the at least one AC/DC modules (10) and transmitted power; and the power scheduling module (30) transmits first transmit power to the first DC/DC module (41) based on a value relationship between the first needed power and the total surplus power. In this method, the charging pile system (100) can accurately meet a charging requirement of a to-be-charged device (60).

摘要： A three-phase interleave converter with a three switching state cell includes: a filter circuit, a power factor correction circuit, a star connection between the filter circuit and the power factor correction circuit, and a second capacitor 7; where an output end of the filter circuit is connected to an input end of the power factor correction circuit by using a conducting wire; the star connection is set on the conducting wire connecting the filter circuit and the power factor correction circuit; one end of the star connection is connected to the conducting wire and the other end of the star connection is connected to one end of the second capacitor 7; and the other end of the second capacitor 7 is connected to an input wire. By using the foregoing solution, the number of capacitors is reduced from the original three to one. In this way, fewer capacitors are used, and the volume is further reduced, thereby increasing the power density.
