Current-Mode Control (Coursera)

For peak current-mode controlled converters, slope compensation, and high-frequency effects are discussed in detail. Upon completion of the course, you will be able to understand, analyze, model, and design high-performance current-mode controllers for dc-dc power converters, including peak current-mode controllers and average current-mode controllers.

We strongly recommend students complete the CU Boulder Power Electronics specialization as well as Course #1 (Averaged-Switch Modeling and Simulation) 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)

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
