Power Magnetic Devices de Scott D Sudhoff

Power Magnetic Devices

Autor Scott D Sudhoff
en Limba Engleză Hardback – 2 dec 2021

Considerăm că Power Magnetic Devices reprezintă un instrument indispensabil pentru inginerii care activează în proiectarea sistemelor de putere, necesitând un nivel de experiență avansat, specific studiilor postuniversitare sau practicii profesionale în electromecanică. Subliniem că această a doua ediție, semnată de Scott D Sudhoff, nu se limitează la o abordare teoretică, ci impune o metodologie riguroasă bazată pe optimizarea algoritmică pentru rezolvarea problemelor de proiectare a inductoarelor, transformatoarelor și mașinilor electrice. Ca și Vencislav Cekov Valchev în Inductors and Transformers for Power Electronics, autorul distilează experiență reală în principii acționabile, însă Scott D Sudhoff extinde discuția prin integrarea algoritmilor genetici și a analizei cu element finit (FEA). Structura volumului reflectă o progresie logică: primele capitole stabilesc fundamentele matematice ale funcțiilor obiectiv și ale optimizării Pareto-optimale, trecând ulterior la circuite magnetice echivalente și pierderi în miez. Un punct forte al acestei ediții este includerea unor secțiuni noi dedicate componentelor magnetice pentru convertoare și invertoare, precum și analiza detaliată a capacității parazite. Credem că valoarea adăugată majoră constă în pachetul de resurse digitale, în special codul MATLAB open-source, care permite cititorului să aplice imediat conceptele de design evolutiv discutate. Spre deosebire de alte manuale tehnice, lucrarea de față reușește să echilibreze analiza fenomenelor de înaltă frecvență, precum efectele de proximitate, cu cerințele practice de management termic și caracterizarea materialelor magnetice moderne.

De ce să citești această carte

Recomandăm această lucrare inginerilor de putere și cercetătorilor care doresc să treacă de la metodele de proiectare prin încercare și eroare la un proces riguros de optimizare matematică. Cititorul câștigă acces la metodologii avansate de calcul și un set complet de instrumente software (MATLAB) pentru modelarea precisă a componentelor magnetice, esențiale în dezvoltarea convertoarelor de înaltă eficiență și a mașinilor electrice performante.

Descriere scurtă

Power Magnetic Devices Discover a cutting-edge discussion of the design process for power magnetic devices
In the newly revised second edition of Power Magnetic Devices: A Multi-Objective Design Approach, accomplished engineer and author Dr. Scott D. Sudhoff delivers a thorough exploration of the design principles of power magnetic devices such as inductors, transformers, and rotating electric machinery using a systematic and consistent framework.
The book includes new chapters on converter and inverter magnetic components (including three-phase and common-mode inductors) and elaborates on characteristics of power electronics that are required knowledge in magnetics. New chapters on parasitic capacitance and finite element analysis have also been incorporated into the new edition. The work further includes:
  • A thorough introduction to evolutionary computing-based optimization and magnetic analysis techniques
  • Discussions of force and torque production, electromagnet design, and rotating electric machine design
  • Full chapters on high-frequency effects such as skin- and proximity-effect losses, core losses and their characterization, thermal analysis, and parasitic capacitance
  • Treatments of dc-dc converter design, as well as three-phase and common-mode inductor design for inverters
  • An extensive open-source MATLAB code base, PowerPoint slides, and a solutions manual
Perfect for practicing power engineers and designers, Power Magnetic Devices will serve as an excellent textbook for advanced undergraduate and graduate courses in electromechanical and electromagnetic design.
