Modern Resonant Converters (MRC) by Prof.Ha
Introduction
Due to our excessive energy use, the earth is becoming hotter and hotter and facing climate change. Renewable and efficient energy consumption is necessary for our sustainable future. Power Electronics is the key technology for efficiently converting various energy.
Modern power electronics is supported by highly efficient wide-bandgap power devices and high-frequency components. The operating frequency is increasing and the parasitic components are highly involved in the operation modes. The resonance in the power converters became the most important feature for better efficiency and power density.
This lecture aims at the fundamental class guide and study for analysis and design of modern resonant converters and giving you deep insight to understand modern resonant converters. It includes impedance matching networks, single-ended resonant converters, isolated resonant converters, and wireless power transfer. This book will guide you to the first step to becoming an expert or great researcher in modern resonant converters. And it will train you with several basic techniques for future development and research.
