|
摘要
对交错并联式单端正激变换器工作模态进行了分析,对关键部分的设计过程进行了计算和说明。采用平均电流法建立系统小信号模型,给出了输出电压闭环控制的补偿函数及参数设计方法,研制了一款原理样机。通过原理样机的试验分析可知,获得的试验结果与理论分析一致,证明了分析结果和系统参数的正确性。
The operating modal of the single-end forward interleaved parallel converter was analyzed,and the design process of its key parts was calculated and explained. A small-signal model was set up in the average current method,the compensation function and parameter design method for the output voltage closed-loop control were given,and an elementary prototype was developed. Finally,experimental analysis of the elementary prototype indicated that the test results were consistent to theoretical analysis and proved the correctness of analysis results and system parameters.
