斩波电路的尖峰电流分析

Analysis of Peak-Current of a Chop-Circuit

分析了斩波电路的开关换流过程，讨论了（ＧＴＲ）开通时尖峰电流的产生机理，并根据建立的电路模型求出了尖峰电流的解析表达式，最后提出了限制尖峰电流的措施及新见解．

The switching and current-exchanging processes of a chop-drcuit are analysed, and the cause of peak-current when the GTR is turned on discussed. Based on the model established, formulas for the peak-current are derived. Moreover, some measurements and new viewpoints to astrain the peak-current and to ensure the cirtcuit working in safety are proposed.
