Input Filter Design (Coursera)

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
