摘要

DC-DC变换器在许多应用中发挥着关键作用。这种应用需要高增益，而不需要对线路和负载的任何变化改变电压。与传统升压拓扑结构相比，二次升压变换器(QBC)提供了中等高的电压增益。然而，由于存在三个RHP零点，使得系统的稳定性和闭环性能难以实现。本文对QBC进行了稳定性分析。本文讨论了QBC中II型和III型控制器的设计。为了保证QBC的稳定运行，提出了II型和III型控制器的组合。并与传统PI控制器进行了性能验证和比较。

Stability Analysis of Quadratic Boost Converter with Different Controllers

DC-DC converters have played a key role in many applications. Such applications demand high gain without any change in voltage for any changes in line and load. Quadratic Boost Converter (QBC) provides a moderately high voltage gain compared to conventional boost topology. However, stability and closed-loop performance are difficult to achieve because of three RHP zeros. A stability analysis of QBC was conducted in this paper. The design of Type II and Type III controllers for QBC is discussed in this paper. A combination of Type II and Type III controllers is proposed for a stable operation of QBC. Performance is validated and compared with the conventional PI controller.
