This course starts with the laws of nature and life mechanisms, and then introduces the laws of electric energy processing and the topological structure of power converters, allowing students to have a comprehensive basic concept of electric energy processing, and can also connect it to nature, biological organs and other fields. There are operation and control mechanisms. Then, let’s go back to the devices and drive circuits required for the power processor, and use the laws of nature to derive various power processor structures. Through such enlightening training, students will be required to find mechanisms from nature or other fields that can be compared to the processing of electrical energy. Then students can realize the infinite magical effects of harnessing the principles of nature and ultimately, the principles of the world have their origins. After taking this course, it is expected that it will broaden students, horizon and stimulate their imagination. Teaching progress 1.
