A method and apparatus for controlling a neutral point clamped inverter circuit, and a neutral point clamped inverter. It is detected that whether the inverter circuit operates in an abnormal state. In a case that the inverter circuit operates in the abnormal state, a control mode of the inverter circuit is changed to a specified control mode in which a transistor that may be damaged is in an off state. In this way, there is not current flowing through the transistor, avoiding damage of the transistor and thereby improving safety of the inverter circuit.

Method and apparatus for controlling modes of inverter circuit, and inverter

A wiring device of photovoltaic power generation equipment includes an aluminum wire and a copper-aluminum transition element. One end of the aluminum end is connected with the aluminum end of the copper-aluminum transition piece, and the other end of the aluminum end is configured to connect with an external connecting component. The copper end is configured to connect with photovoltaic power generation equipment. In the wiring device of the photovoltaic power generation equipment provided in the present application, the copper-aluminum transition piece is arranged at the position of the photovoltaic power generation equipment, and the aluminum end of the copper-aluminum transition piece is connected to the external connecting component by the aluminum wire, avoiding using copper wire for long-distance conduction. The cost of the aluminum wire is much lower than that of the copper wire. Therefore, the cost of the wiring device provided by the application is reduced.

Embodiments of the present invention provide a task scheduling method and apparatus on a heterogeneous multi-core reconfigurable computing platform. The method includes: when determining that a to-be-executed hardware task is in a ready state, adding the to-be-executed hardware task into a target hardware task queue corresponding to a function of the to-be-executed hardware task; reconfiguring, according to a priority of the to-be-executed hardware task and a usage status of multiple reconfigurable resource packages, at least one reconfigurable resource package in the multiple reconfigurable resource packages into a target intellectual property IP core that can execute the to-be-executed hardware task. According to the embodiments of the present invention, a more proper resource reconfiguration occasion can be determined, and a more appropriate reconfigurable resource package can be used for resource reconfiguration, thereby reducing reconfiguration overheads and improving utilization of reconfigurable resources in a task scheduling process.

Task scheduling method and apparatus on heterogeneous multi-core reconfigurable computing platform

A method for task scheduling on a heterogeneous multi-core reconfigurable computing platform is disclosed, the method includes: determining an execution manner of a target task according to popularity of the to-be-executed target task and usage of a reconfigurable resource of the heterogeneous multi-core reconfigurable computing platform, where the execution manner includes a hardware manner or a software manner, for the target task, there is no corresponding target intellectual property IP core for executing the target task on the heterogeneous multi-core reconfigurable computing platform, the popularity of the target task is used to indicate central processing unit CPU usage of the target task, and the usage of the reconfigurable resource is used to indicate a usage status of the reconfigurable resource; and executing the target task according to the determined execution manner.
