Input Filter Design from Coursera

This course can also be taken for academic credit as ECEA 5707, part of CU Boulder’s Master of Science in Electrical Engineering degree.

This is Course #3 in the Modeling and Control of Power Electronics course sequence. After completion of this course, you will gain an understanding of issues related to electromagnetic interference (EMI) and electromagnetic compatibility (EMC), the need for input filters and the effects input filters may have on converter responses. You will be able to design properly damped single and multi-section filters to meet the conducted EMI attenuation requirements without compromising frequency responses or stability of closed-loop controlled power converters.

We strongly recommend students complete the CU Boulder Power Electronics specialization as well as Courses #1 (Averaged-Switch Modeling and Simulation) and #2 (Techniques of Design-Oriented Analysis) before enrolling in this course (the course numbers provided below are for students in the CU Boulder's MS-EE program):

● Introduction to Power Electronics (ECEA 5700)

● Converter Circuits (ECEA 5701)

● Converter Control (ECEA 5702)

● Averaged-Switch Modeling and Simulation (ECEA 5705)

● Techniques of Design-Oriented Analysis (ECEA 5706)

After completing this course, you will be able to:

● Understand conducted electromagnetic interference (EMI) and the need for input filter

● Understand input filter design principles based on attenuation requirements and impedance interactions.

● Design properly damped single-stage input filters.

● Design properly damped multi-stage input filters.

● Use computer-aided tools and simulations to verify input filter design

Reviews summary

Input filter design: practical emi solutions

According to students, this course provides an excellent and crucial deep dive into input filter design, especially for power electronics professionals. Learners consistently praise the instructor's brilliant expertise and crystal clear explanations of complex topics like electromagnetic interference (EMI) and impedance interactions. The course is highly valued for its focus on properly damped single and multi-section filters, with many finding the simulation examples and practical application highly beneficial. However, some learners caution that a very strong background in power electronics prerequisites is essential, as the pace can be fast and the content is theory-heavy in parts, requiring significant prior knowledge.

Computer-aided tools and examples aid design verification.

"The simulation examples using MATLAB were super helpful."

"The use of computer-aided tools to verify designs was also a huge plus."

"The theoretical foundation provided is strong... My only minor critique is that the simulation exercises, while shown, could benefit from more interactive elements."

Focuses on real-world damped filter design and applications.

"The content on multi-stage damped filters was incredibly practical... I feel much more confident in designing filters for my projects now."

"The focus on properly damped filters is highly relevant for real-world applications. This course is a significant asset for anyone working in power electronics."

"The best course on EMI filter design I've taken online... Highly practical for professional engineers."

Brilliant explanations simplify complex engineering concepts.

"The instructor's explanations of EMI/EMC concepts and impedance interactions were crystal clear."

"Excellent deep dive... The instructor is brilliant and makes complicated topics like EMI attenuation and impedance interactions understandable."

"A crucial course... The instructor's clear lectures and the practical examples make this a standout."

Covers complex material quickly, especially multi-stage designs.

"Some parts felt a bit rushed, especially the multi-stage filter design."

"The pace sometimes felt too fast for the amount of new information, especially in the later modules."

"I felt the course jumped quickly into complex material without enough scaffolding."

Strong prior knowledge is vital for success in this course.

"The course assumes a strong background. The prerequisites listed were absolutely essential, maybe even more so than emphasized."

"I found this course incredibly difficult. The prerequisites were not sufficiently emphasized, and I felt like I was constantly playing catch-up."

"Make sure you are *very* comfortable with the recommended prerequisites before starting."
