摘要
Boost变换器的开环传递函数有一个位于右半平面的零点,使得使用单一的反馈电压环难以同时保证系统在受到某种扰动作用时,既有很好的动态品质又不致造成系统失稳.平均电流控制模式是提高Boost变换器稳定性和动态调节特性的有效方法.分析并推导了Boost变换器的平均电流控制模型,通过对系统的分析和仿真,其结果证明了所建模型的正确.
It is difficult Boost converter has good dynamic adjustment performance and stability if the system using a single voltage feedback loop get some interference. The reason is Boost converter has a zero point in right half plane. Average current control mode is an effective way to improve dynamic adjustment performance and stability of Boost converter. An average current control mode of Boost converter is analyzed and derived. Through analyzing and simulating the system, it is proved that the mode is correct.
