Abstract

A component-level power electronics device is able to switch between a shutdown mode, a normal working mode, and a safe working mode, which includes: when the component-level power electronics device fails to receive the periodic communication signal, maintaining or switching to the shutdown mode; when the periodic communication signal received by the component-level power electronics device includes a heartbeat frame and does not include a voltage adjustment instruction, switching to the normal working mode; or when the periodic communication signal received by the component-level electric power electronics device includes the heartbeat frame and also includes the voltage adjustment instruction, switching to the safe working mode. The three working modes can ensure safety of both a device and a person, have a fast response speed, and are easy to implement.
