摘　　要：本文研究两重化Buck变换器的设计方法。在研究基本型Buck变换器的结构和参数计算方法后,得到两重化Buck变换器的结构和主要器件的参数计算方法。在此基础上,基于相同的输入输出设计要求,设计了基本型和两重化Buck变换器,并得到具体的器件参数。通过PLECS仿真软件进行仿真分析,对比了两者的电气性能。仿真结果表明,两重化Buck变化器输出电压和电流纹波小,电流高次谐波含量低,电气性能显著优于基本型Buck变换器。This paper studies the design method of interleaved Buck converter.By analyzing the structure and parameter calculation method of the basic Buck converter,the structure and the parameter calculation method of interleaved Buck converter are obtained.On this basis,based on the same input and output design requirements,this paper designes the basic type and interleaved Buck converter,and obtaines the specific device parameters.The electrical performances of the two converters are compared by simulation analysis with PLECS simulation software.The simulation results show that,the output voltage and current ripple of the interleaved Buck converter are lower,the high-order harmonic current content is lower,and the electrical performance of the interleaved Buck converter is significantly better than that of the basic Buck converter.
