“工程实践与科技创新”是一项包含四个阶段的系列课程，通过强化的实验操作训练，帮助学生获得一定的工程研发体验。引导学生在解决工程实际问题中提升测量技巧、工程设计能力和高效率团队协作能力。

“工程实践与科技创新IIIA”是第三阶段课程模块。学生将设计并实现一个带有单片机监控电路的开关稳压电源系统，这是一项中等复杂度的工程实际设计问题。设计过程中，要求设计者折中地考虑和确定软件复杂度和硬件复杂度、系统整体性能和局部性能。

要求学生具有电路设计、程序设计的基础知识和基本实验技能，并具备一定的工程系统综合设计能力。

学生以多人为小组开展项目工作。小组得分中，平时活动参与度评价约占10%，实验工程原型作品评价约占65%，设计报告评价约占25%。组长负责给出组内成员贡献程度评分，作为个人得分的重要依据。

Engineering Practice and Technology Innovation is a series of laboratory courses including four stages, which are designed to help undergraduates obtain engineering research and development experiences by intensive laboratory training. The course guides the students to improve their measurement skills, design abilities and to build capacity for high performance teamwork in solving practical engineering problems.

Engineering Practice and Technology Innovation Part IIIAisone of the third stage course modules. The students are required to design a DC-DC Switch-mode Power Supply System supervised by a Single-Chip Microcontroller, which is a practical engineering subject with medium complexity. The designers should carefully keep trade-offs between the hardware and the software complexity, the whole and the partial performance.

Some fundamental knowledge of electronic circuits design and program design as well as basic experimental skills is supposed to be the prerequisite.

The students are required to implement their projects among a three-member group. Grading for engineering prototypes makes up approximately 65% of final grade for each group, while those for participation in ordinary activities and design reports make up10% and 25% respectively. Furthermore the group leaders are required to evaluate each member’s contribution, which will be a significant hint of final grade for each student.
