Power Electronic Circuit Fault Simulation Based on LabVIEW and Simulink

为了对电力电子电路故障时的工作情况进行探讨与分析,本文以三相桥式全控整流电路为例,基于LabVIEW和Simulink建立了电力电子电路在故障情况下的电路仿真模型,对电路故障时的工作情况进行了仿真分析,仿真结果展示于LabVIEW界面中,仿真参数亦可在界面直接修改。该故障仿真对理解电路原理、推测故障原因及在电路设计时选取器件参数等有参考意义。

In order to discuss and analyze the working conditions when the power electronic circuit fails,this article take the threephase bridge full-controlled rectifier circuit as an example,established the circuit model of the power electronic circuit using LabVIEW and Simulink under fault conditions,then simulate and analysis the working situation of circuit faults.The simulation results are displayed in the LabVIEW interface,and simulation parameters can be modified directly on the interface also.The fault simulation has reference significance for understanding the circuit principle,estimating the cause of the fault,and selecting the device parameters when designing the circuit.
