Edris Vision/Mission • Power electronics is one of the fastest changing “enabling infrastructure technologies” in electrical engineering. • It has made and continues to make significant impacts on power and energy infrastructures, which constitute one of the pillars of the foundation of our society and the rest of the world. • Power electronics-based controllers are the key elements for transforming the electric grid from being a “passive” to be an “active” system, i.e., flexible, controllable, securely utilizable up to its maximum capacity, and delivering power with the quality needed for a “digital” society.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
