Informationen zum Autor Dr. P. C. Sen is Emeritus Professor of Electrical and Computer Engineering at Queen's University, Canada. Dr. Sen received his Ph.D. degree at the University of Toronto in 1967. He has worked for industries in India and Canada and was a consultant to electrical industries in Canada. He has authored over 215 technical papers in the general area of electric motor drives and power electronics. He is the author of two internationally acclaimed textbooks: Principles of Electric Machines and Power Electronics and Thyristor DC Drives (Wiley, 1981). He has taught electric machines, power electronics, and electric drive systems for over 45 years. His fields of interest include power electronics, electric drive systems, switching power supplies, wind energy systems, digital control, fuzzy logic control, and modern control techniques for power electronics and motor drive systems. Klappentext Principles of Electric Machines and Power Electronics, Third Edition combines the traditional areas of electric machinery with the latest in modern control and power electronics. Multi-machine systems, brushless motors, and switched reluctance motors are covered, as well as constant flux and constant current operation of induction motors. Additional material is included on new solid state devices such as Insulated Gate Bipolar Transistors and MOS-Controlled Thyristors.
