摘要
为了让学生了解电力电子技术最新研究进展,对DC-DC变换器实验进行了改进,开展分数阶和整数阶Buck变换器的对比研究。推导两种变换器的传递函数,设计电压单闭环控系统,构造分数阶电感和电容的分抗链等效电路,通过伯德图、时域仿真和硬件实验对两种变换器进行对比,理解分数阶变换器的优越性。实验方案满足新工科和工程教育的高阶性和创新性要求,为“电力电子技术”课程教学改革提供新的思路。
To let students understand the latest research progress in power electronics technology,improvements are made to the DC-DC converter experiment,and a comparative study of fractional-order and integer-order Buck converters is carried out.The transfer functions of the two converters are derived,a voltage single-closed-loop control system is designed,and the fractional-order inductor and capacitor fractional reactance chain equivalent circuits are constructed.The two converters are compared through Bode diagrams,time-domain simulations,and hardware experiments to understand the advantages of fractional-order converters.The experimental scheme meets the high-level and innovative requirements of new engineering and engineering education,providing new ideas for the teaching reform of the Power Electronics Technology course.
