摘要
为解决直接AC/AC变换器的输出纹波计算问题,本文建立了以DC/DC变换器结构为基础的六种AC/AC变换器的理想模型。利用这些理想模型,DC/DC变换器的一般分析方法可方便地引入到AC/AC变换器的分析中,然后,论文以Buck型AC/AC变换器为例,给出其电路输出纹波系数的计算公式。为了证明理论分析的正确性,搭建了实验电路,实验结果与理论计算得到了很好的吻合。
To resolve the problem of output voltage and current ripple calculation for direct AC/AC converter, the ideal model of AC/AC converter based on DC/DC converter are presented in this paper. By using these models, the common analysis method for DC/DC converter can be easily introduced into the analysis for AC/AC converter. Then, the voltage and current calculation for Buck type AC/AC converter is given in this paper. To satisfy the correction of the theoretical analysis, an experiment circuit has been built, and the result show the excellent match to the theoretical calculation.
