摘　　要： 利用FPGA的并行计算特性,在电力电子模型的实时仿真中FPGA可以实现纳秒级的仿真步长,能够更加真实的呈现电力电子开关器件的特性。通过分析Buck变换器在电感电流连续导通模式下的数学模型,基于XILINX公司的System Generator搭建了Buck变换器的数学模型,并对其进行了实时仿真,与器件仿真的结果进行了对比,从仿真结果中,可以看出该数学模型的有效性,可以在一定误差范围内取代Buck变换器的器件模型,同时也为实际的电路研制和调试提供了思路。 Using the parallel computing characteristics of FPGA, the FPGA can realize the nanosecond simulation step size in the real time simulation of power electronic devices and models, which can show the characteristic of power electronic switching devices more reality. Through the analysis of the buck converter in inductor current continuous mode of mathematical model, with the Xilinx system generator tools we built the mathematical model of the buck converter, and carries on the real-time simulation, and compared with device simulation results, from the simulation results, it can be seen the effectiveness of the mathematical and can replace the device model of Buck converter in a certain error range, and also for the actual circuit design and debugging provides a way.
