摘要
介绍了隔离式Cuk变换器的拓扑结构及在光伏发电系统中的应用。隔离式Cuk变换器能够高效率的传递功率和减小纹波的输出,同时采用改进准滑模控制技术跟踪光伏系统的最大功率点,提高系统的性能和最大功率跟踪速度,实现强鲁棒控制。并进行仿真研究,验证了方法的有效性。
The paper presents the topological structure of isolated Cuk converter and application in photovohaic power generation systems. The isolated Cuk converter can efficiently transit the power and reduce the ripple wave output. Mean- while the improved quasi-sliding mode control technology is used to track the maximum power point of the photovoltaic system, to increase the system performance, the maximum power tracking speed and achieve strong robust control. The simulation matlab has verified the validity of the method.
