Abstract: A converter and a power supply system are disclosed, and relate to the power electronics field, to resolve a problem that a sampling circuit in an OBC circuit is relatively complex. The converter includes an alternating current unit, a switching unit, a conversion unit, a direct current unit, and a controller. The alternating current unit includes a U line, a V line, a W line, and an N line. The N line is connected to a ground of the controller, so that the controller can be directly connected to the U line, the V line, and the W line, to collect a voltage of the U line, a voltage of the V line, and a voltage of the W line. This simplifies the sampling circuit.

Abstract: This application provides a model training-based communication method and apparatus, and a system, to effectively decrease a data amount of a parameter transmitted between the communication device and the central server. The method includes: The communication device determines a change amount of a first model parameter value. If the communication device determines, based on the change amount of the first model parameter value, that a first model parameter is stable, the communication device stops sending an update amount of the first model parameter value to the central server in a preset time period. The update amount of the first model parameter value is determined by the communication device based on user data in a process of performing model training. The communication device receives a second model parameter value sent by the central server.

Abstract: An autonomous lane change method and apparatus, and a storage medium are provided. The method includes: calculating a local neighbor feature and a global statistical feature of an autonomous vehicle at a current moment based on travel information of the autonomous vehicle at the current moment and motion information of obstacles in lanes within a sensing range of the autonomous vehicle (S1101); obtaining a target action indication based on the local neighbor feature, the global statistical feature, and a current control policy (S1102); and executing the target action according to the target action indication (S1103). It can be learned that, on the basis of the local neighbor feature, the global statistical feature is further introduced into the current control policy to obtain the target action indication. Therefore, the target action obtained by combining local and global road obstacle information is a globally optimal decision action.

Abstract: The invention provides a method, an apparatus and a system for controlling network congestion. The method includes: sending a control frame or a beacon frame to a station in a network when network congestion occurs, so as to instruct the station to enlarge a contention window when the station needs to send data. The method can achieve the congestion control for a network before collision occurs to a station, avoiding more serious network congestion caused by each station still contending for a channel after the network congestion occurs; since an access point can send a control frame or a beacon frame to the station when determining that congestion occurs to the current network, to instruct the station which needs to send data to re-determine a backoff time, a rapidly congestion relief of the whole network is achieved, and also a fair channel contention of each station is guaranteed.
