摘　　要：针对电力电子系统开关器件较多、数学分析较复杂且其FPGA建模开发周期长等问题,文章提出了一种用于电力电子拓扑仿真的FPGA快速建模方法。其首先对电力电子的开关器件进行等效以简化数学模型,省略了复杂的数学分析;然后,运用Matlab自带的power-analyze函数求得电力电子拓扑的系统矩阵;最后,根据所得的系统矩阵快速简便地建立系统的FPGA模型,将FPGA的开发周期缩短了1/4左右。通过与SimPowerSystem模型对比,仿真结果验证了所提方法的有效性。Power electronic system has many switching devices and its mathematical model is complex and hard to analysis.In addition,the cycle of FPGA modeling is long.This paper proposed a FPGA rapid modeling approach for power electronic topology simulation.Firstly,a simplified mathematical model is obtained by the switch equivalent of power electronic switching devices,which helps to simplify the complicated mathematical analysis;secondly,power-analyze function is adopted to obtained system matrix;finally,according to the matrix of the system obtained,new FPGA model will be built easily and quickly,which can shorten 1/4 development time of FPGA.The simulation results demonstrate the effectiveness of the proposed method compared with the SimPowerSytem model.
