The essential textbook for all marine engineers and ETO officers, covering advanced electrotechnology theory. Designed as a companion to Reeds vol 6: Basic Electrotechnology for Marine Engineers, this indispensable textbook goes beyond the scope of the earlier book to cover more advanced aspects of theory. This comprehensive coverage of more advanced topics makes this an essential book for professional trainees studying for merchant navy marine engineering Certificates of Competency (CoC). It also covers the electrotechnology syllabi for undergraduate and postgraduate students pursuing degrees in marine and electrical engineering. This edition has been revised, updated and expanded to remain current, with new additions on control systems, machine learning and AI, plus advances in semiconductors and microelectronics. It includes sample exam questions with worked examples to help improve assessment outcomes.
