Sinossi
Written in plain language, Fundamentals of Power Electronics sets forth the basic principles of power electronics. Starting with the various types of devices, protection, and series and parallel operation of silicon controlled rectifiers, it details all the aspects of power electronics essential to building a strong foundation for the further study and practice of industrial or power electronics engineering. The author devotes considerable attention to a wide variety of applications, from AC and DC motors, heating, and welding to HVDC transmission and thyristor controlled electrical drives.
Fundamentals of Power Electronics is filled with diagrams that clarify the concepts presented. Each chapter includes sections containing numerous examples and short questions with answers. An appendix furnishes a series of power electronics experiments that explore SCR characteristics, UJT firing circuits, voltage and current commutation, triac characteristics, and the RC triggering scheme of SCR.
