基于典型层次教案设计提高学生电气仿真能力

本文针对当前电气电子课程设计中暴露出的学生仿真能力不足的问题，以Boost变换器仿真为例，建立了统一状态方程，设计了典型层次教案，启发学生主动性思考，使其不仅知其然还要知其所以然，并提高实际仿真能力。文中还提出了一种电力电子数值仿真中状态空间模型的标准化方法，经实际仿真验证，能够有效提高仿真速度。不同层次的典型教案设计可以更好地贯彻因材施教，激发学生学习兴趣，充分发挥主观能动性。

Boosting Students' Abilities in Electrical Simulation Based on Typical Cascade Tutorial

Aiming at problems in students＇ simulation abilities emerged from electrical curriculum designs, this paper presents a typical design with cascade tutorial based on the example of the simulation of boost converter with universal state-space equations. It will be heuristic and benefit for students to think with go-aheadism, knowing not only what but also how and improving practical simulation abilities. A novel model normalization method is also provided for electrical electronics simulation, which is proved to be helpful for improving speed by practical simulation results. Typical tutorials with different levels can also satisfy the principle of teaching in accordance of students＇ aptitude, and inspire their interests in studies, which will be helpful to motivate themselves.
