Fundamentals of Power Electronics and Drives by Dr. Jigneshkumar Desai provides a comprehensive, practice-oriented introduction to modern power electronics and electrical drive systems. Designed for undergraduate and postgraduate students as well as practicing engineers, this textbook seamlessly integrates theory with real-world applications through extensive MATLAB/Simulink simulations and hands-on design examples.

The book systematically covers semiconductor switches (diodes, thyristors, MOSFETs, IGBTs), rectifiers (single-phase and three-phase converters, dual converters), DC-DC converters (buck, boost, buck-boost, choppers), and inverters (single-phase, three-phase, SPWM control). A major emphasis is placed on electrical drives and control systems, including DC drives, vector control of induction motors, scalar control methods, and advanced drive systems for BLDC and PMSM motors, with detailed coverage of speed control, torque regulation, and field-oriented control.

Practical applications such as SMPS, UPS systems, and relay circuits are explored alongside a unique chapter on PCB design using KiCad, featuring complete design workflows from schematic capture to manufacturing file generation. The book addresses critical power quality challenges—harmonics, ripples, EMI, and switching transients—with proven mitigation techniques and compliance guidance for IEEE 519 and IEC 61000 standards.

With hundreds of circuit diagrams, waveforms, simulation models, worked examples, and design calculations, this book provides both a solid theoretical foundation and practical skills essential for careers in power systems, renewable energy, electric vehicles, and industrial automation.
