GATE Exam Preparation: Fundamentals and Solved Problems in Power Electronics

Preparing for competitive engineering exams requires a rock-solid grasp of foundational circuits and the ability to solve complex analytical problems under time constraints. This text-based course breaks down the essential principles of power electronics, helping you bridge the gap between academic theory and exam-style problem-solving. You will begin by establishing a strong foundation in core terminology, semiconductor switch characteristics, and mathematical analysis techniques before tackling actual exam questions. What you'll learn: Understand the operational principles of power semiconductor diodes, thyristors, BJTs, MOSFETs, and IGBTs; Analyze single-phase and three-phase uncontrolled and controlled rectifiers with various load types; Evaluate the performance of DC-DC converters including buck, boost, and buck-boost topologies; Solve previous years' exam questions on power electronics with clear, step-by-step mathematical derivations; Apply modern power conversion concepts and efficiency calculations to academic problems. The course starts with fundamental definitions and circuit laws, gradually progressing through detailed written analyses of classic exam problems. This course is designed for engineering students and graduates preparing for competitive exams who want to strengthen their conceptual understanding of power electronics.
