A low-delay and high-speed transmission strategy for emergency priority insertion
In power electronics systems,some special topological circuits can't be directly protected when they fail,so it is necessary to upload fault signals to the upper controller for unified and coordi-nated protection,so as to avoid secondary faults.However,the short-circuit fault time that power de-vices can withstand requires a small transmission delay for emergencies such as faults.Therefore,em-ploying an appropriate low-latency transmission strategy is crucial to ensure timely response and pro-cessing of urgent signals.To address this,a low-latency high-speed transmission strategy with prio-rity insertion for emergency events was designed.Firstly,the input and output signals of the power electronic device were analyzed to determine the priority of different data types,with the highest prio-rity assigned to emergency events,ensuring their insertion into the communication link for transmis-sion at any time.Secondly,based on the module segmentation principle,relevant modules were pro-grammed using verilog language.Finally,the correctness of emergency priority insertion strategy was verified by software simulation and hardware test.The results show that the strategy can effectively reduce the transmission delay of emergency events,enabling the system to respond quickly to urgent events,and achieve the goal of maintaining the safety of power electronics systems.
