Lecture 06 Charging infrastructure, DC-DC Converters - III

🚗⚡ Charging Infrastructure & DC–DC Converters – III | Flyback & Forward Converters | Electric Vehicles | Lecture 06 In this lecture, we introduce Isolated DC–DC Converters, which provide galvanic isolation, improved safety, and greater design flexibility for electric vehicle power conversion systems. The lecture begins with transformer models and the dot convention, followed by a detailed analysis of the Flyback Converter and Forward Converter operating in Continuous Conduction Mode (CCM). Step-by-step derivations of voltage conversion ratios, inductor current ripple, minimum inductance, output capacitor design, and operating waveforms are presented to help build a strong foundation in isolated power converter design. 📚 Topics Covered ✅ Introduction to Isolated DC–DC Converters ✅ Advantages of High-Frequency Transformer-Based Converters ✅ Ideal, Complete, and Simplified Transformer Models ✅ Transformer Dot Convention ✅ Flyback Converter: Operating Principle ✅ Flyback Converter Steady-State Analysis ✅ Voltage Conversion Ratio ✅ Diode Current and Waveform Analysis ✅ Minimum Magnetizing Inductance Design ✅ Output Capacitor Design ✅ Limitations of Flyback Converters ✅ Forward Converter: Operating Principle ✅ Forward Converter Steady-State Analysis ✅ Voltage Conversion Ratio and Waveforms ✅ Inductor and Capacitor Design Considerations 🎯 Who Should Watch?
