An introduction to power conversion equipment and systems for high-energy particle accelerators will be presented. Typical types of power conversion equipment used in accelerators including high voltage and high power DC and pulsed power supplies, modulators and fast kicker pulsers, medium power thyristor and switchmode converters and low power bipolar trim supplies will be covered. The advantages and limitations of different topologies including performance and cost considerations will be described. The matching of power supplies to typical application circuits, such as magnets, kickers, pulse-forming networks, etc., and the merits and performance of the integrated systems will be discussed. Basic feedback control system designs and implementations for current and voltage regulation will be presented. Power line considerations, power factor, harmonics and system impedance effects will also be covered. Machine and personnel protection interlocks, strategies for electromagnetic compatibility, reliability analysis and overall performance of power conversion equipment will be discussed. The course will tend towards qualitative descriptions and concepts rather than elaborate analysis. Participation in class discussions, a computer laboratory and homework to enhance concept understanding will be required. Prerequisites: A fundamental understanding of electrical and electronics technology and mathematical knowledge through basic calculus. Textbook to be provided: "Introduction to Power Electronics" by David W. Hart, Prentice Hall publishers.
