Only by understanding both semiconductor device theory and high-power application can the designer be sure of selecting the correct power device for a given application. This book covers both the switches themselves and the circuitry required to make them work effectively. In this revised and updated version the author has added an entire new section on passive components – capacitors, soft magnetic materials, and resistors. In addition to describing their properties, characteristics, and ratings, he illustrates their use with examples. Important additions to the applications section include converter underlap, reversible converters, and standby and uninterruptible supplies. Many more real examples and problems ensure that the reader gains a thorough working knowledge. Part 1 covers power device electrical and thermal characteristics and how they relate to a device’s structure; part 2 describes device driving and protection techniques; part 3 covers power electronic applications and part 4 is the new section on passive components – capacitors, soft magnetic materials, and resistors.
