摘要
本文分析研究了基于电感或变压器绕组电压积分的间接电流型控制技术,通过对电感或变压器绕组的电压积分,可以将交变的脉冲波积分成三角波,该三角波能表征开关电流的变化规律,因此可以作为PWM的三角载波,从而实现占空比的调节。文中以推挽正激变换器拓扑为例,对其进行了原理实验研究。
The indirect current mode control (ICMC) which integrates the inductor voltage or the transformer's windings voltage is investigated. The pulse wave is integrated into a triangle wave which can represent varied character of the switch's current, So the triangle carrier can adjust duty ratios. Take push-pull forward converter topology as an example, the principle experiment of the indirect current mode control is made.
