摘要
在“电力电子技术”课程中,单相桥式电路是一种基础的DC/AC逆变电路。但在教学实践中,往往直接给出电路结构,只注重波形绘制和公式推导,导致学生难以深入理解。因此,基于Buck电路,对桥式逆变电路拓扑进行研究,提出一种渐变推演的教学方法。该方法不仅能够让学生循序渐进地理解桥式逆变电路的产生及其工作原理,同时能够引导学生对电力电子拓扑推演的思考,提高对电力电子课程的学习兴趣。
In the course of Power Electronics Technology,single-phase bridge inverter circuit is a basic DC/AC inverter circuit.However,in practice,the structure of bridge circuit is often given directly,and only the waveform and formula of each circuit are focused,which makes it difficult for students to deeply understand the essential principle.Therefore,a teaching method of gradual topology derivation of bridge inverter circuit is proposed based on Buck circuit.This teaching method not only enables students to understand the generation of bridge inverter circuit and its working principal step by step,but also enhances their understanding and thinking of power electronics topology deduction,and enhance their learning interest in power electronics courses.
