“探究教学”在是以教师为引导,学生参与合作为主体的教学方式。文章主要是在以引导学生在实践中的调研分析的基础上,结合自身专业的特点和生产生活实际情况设计了一款输出电压精度高、纹波率小,总体性能优良,基于单端反激式拓扑结构的25W、48V转+5V、+15V、-15V三路输出反激式开关电源。Saber2007对所设计电路的部分关键模块进行的仿真实验的结果显示:本三路输出反激式开关电源电路简单、有效输入电流范围宽、电源的动态响应速度快、控制精度高的开关电源,尤其适合在对电源精度要求较高或负载条件较差的情况下使用。在教师的引导下,通过实际的项目创造个性化学习。
“Inquiry Teaching ” is a teaching method taking teachers as guide and students participating in cooperation as the main body. The article is based on the guidance of students in the research and analysis based on the practice, combined with their own professional characteristics and the actual production and living conditions designed a high output voltage accuracy, low ripple rate, the overall performance is excellent, based on single-ended flyback Topology 25W, 48V to + 5V, + 15V, -15V three-way output flyback switching power supply. Saber2007 part of the design of the circuit simulation of the key modules of the simulation results show that: The three-way output flyback switching power supply circuit is simple, effective input current range, dynamic response speed, high precision switching power supply, in particular Suitable for high precision power requirements or poor load conditions to use. Under the guidance of teachers, create personalized learning through practical projects.
