Description
Book SynopsisDesigned to complement a range of power electronics study resources, this unique lab manual helps students to gain a deep understanding of the operation, modeling, analysis, design, and performance of pulse-width modulated (PWM) DC-DC power converters. Exercises focus on three essential areas of power electronics: open-loop power stages; small-signal modeling, design of feedback loops and PWM DC-DC converter control schemes; and semiconductor devices such as silicon, silicon carbide and gallium nitride.
Meeting the standards required by industrial employers, the lab manual combines programming language with a simulation tool designed for proficiency in the theoretical and practical concepts. Students and instructors can choose from an extensive list of topics involving simulations on MATLAB, SABER, or SPICE-based platforms, enabling readers to gain the most out of the prelab, inlab, and postlab activities.
The laboratory exercises have been taught and continuously impr
