Reiss uses P. T. Barnum's Joice Heth hoax to examine the contours of race relations in the antebellum North. Barnum's first exhibit as a showman, Heth was an elderly enslaved woman said to be the 161-year-old former nurse of the infant George Washington. Seizing upon the novelty, the newly emerging commercial press turned her act--and especially her death--into one of the first media spectacles in American |

Sommario/riassunto |
|
Advanced Matrix Converters: Topology, Modulation, and Control is a comprehensive guide for readers interested in developing advanced direct AC-AC converters, commonly known as matrix converters (MCs). These MCs offer an all-silicon and environmentally friendly solution that has garnered increasing attention in recent years due to their ability to eliminate bulky passive components and improve the converters' power density, conversion efficiency, and reliability. This book covers the principles of topology construction, advanced modulation strategies, application areas, and control methods. It includes topics such as efficient AC-AC conversion, multi-level conversion, and high-performance adjustable speed drives. It is an essential resource for researchers, engineers, and designers who must select the most appropriate new topologies and control methods for specific applications. Focuses on novel topologies, enhanced modulation strategies, and high-performance control methods Covers the concept and operation of advanced direct AC-AC conversion technology from fundamentals to applications Includes worked examples and solutions to problems. |
