This is Course #5 in the Modeling and Control of Power Electronics Specialization. The course is focused on modeling and control of grid-tied power electronics. Upon completion of the course, you will be able to understand, analyze, model, and design low-harmonic rectifiers and inverters interfacing dc loads or dc power sources, such as photovoltaic arrays, to the single-phase ac power grid.

We strongly recommend students complete the CU Boulder Power Electronics Specialization as well as Courses #1 (Averaged-Switch Modeling and Simulation) and #4 (Current-Mode Control) before enrolling in this course.
After completing this course, you will be able to:
● Understand the operating principles of low-harmonic, high power factor rectifier and inverters
● Model and design current shaping and voltage control loops in power factor correction (PFC) rectifiers
● Model and design control loops in single-phase dc-to-ac inverters
● Design photovoltaic power systems tied to the single-phase ac power grid
● Use computer-aided tools and simulations to verify the design of rectifiers and inverters
