# Experimental power electronics curriculum and reference

Alex J. Hanson, an assistant professor in the department of electrical and computer engineering at The University of Texas at Austin, created the TI experimental power electronics reference and curriculum. This hands-on, experimental curriculum with lectures and labs teaches power electronics to university students. The videos in this series provide a knowledge base and refresher for current engineers. A project is also included that leverages power electronic knowledge to create a real-world solution.
