Brief Handbook Description: This unit of study aims to provide the fundamentals of power electronics. It provides description of the operation principles and control of these blocks. Through analysis and design methodologies, it delivers an understanding of modern enabling technologies associated with energy conversion. Through laboratory hands-on experience on actual industrial systems, such as electrical motor drives, robotic arms, and power supplies, it enhances the link between the theory and the "real" engineering world.

The following topics are covered:

Introduction to power electronic converters and systems; analysis, design, simulation, and operation of power electronic converters; power semiconductor devices; passive devices; the conversion toplogy includes DC/DC, DC/AC, AC/DC, and AC/AC for various applications.
Assumed Knowledge: 1. Differential equations, linear algebra, complex variables, analysis of linear circuits. 2. Fourier theory applied to periodic and non-periodic signals. 3. Software such as MATLAB to perform signal analysis and filter design. 4. Familiarity with the use of basic laboratory equipment such as oscilloscope, function generator, power supply, etc. 5. Basic electric circuit theory and analysis
