课程详情

The course is an introduction to switched-mode power converters. It provides a basic knowledge of circuitry for the control and conversion of electrical power with high efficiency. These converters can change and regulate the voltage, current, or power; dc-dc converters, ac-dc rectifiers, dc-ac inverters, and ac-ac cycloconverters are in common use. Applications include electronic power supplies, aerospace and vehicular power systems, and renewable energy systems.

说实话,我的电路基础知识还是在MITx的6.002x上补的。虽然大学学过一些电路课,但早就还给老师了。没想到能够在MOOC上重新找回些电路的信心。

这门课讲的是开关电源,所有人手边就有的东西。然而,它的原理就不是所有人都说得清楚的了。为何要用开关电源?开关电源效率如何?怎么样能让输出保持稳定?如何设计符合要求的开关电源?这都是这门课要回答的问题。而且,从我上课的经历来看,这门课完美地回答了这所有问题。如果想了解这方面的知识,这门课就是最好的选择。

可能有的人不了解这门课的老师和所在学校。科罗拉多大学波德分校绝对是名声在外,出过很多诺贝尔奖。Robert Erickson教授则是电源领域著名教科书Fundamentals of Power Electronics的作者,Amazon评分高达4.5。大家都说他的书通俗易懂,讲解清晰。

由于我的电路知识才捡起来没多久。所以上课的时候还是很花了些力气的。每周做作业的时间也多在4个小时左右。不算一门很轻松的课。好在作业并不算多。努力一下就坚持下来了。做完作业也很有成就感。而且作为典型的工科课程,老师很强调估算的作用。如果是要估算的题目,你去使用matlab得出精确解了反而不能得分。其实这正是工程的精髓,所有设计都是从估算开始的。

总的来说,一门好课。非常值得想了解的人投入时间。
