72651 - Power Converters for Renewable Energy Systems (2nd cycle)

Learning outcomes

The student will receive operating principles and design cues for power converters, aimed at optimal efficiency.

This knowledge can be used for analysis, design and control of power stage in wind farms and photovoltaics.

Course contents

Power Electronics

• Review of most common power electronic devices for static energy conversion: Diodes, MOSFET, IGBT.
• Basic Configurations  of DC / DC converters: buck, boost, buck-boost, flyback, forward.
• Modulation Techniques for DC / DC converters.
• Advanced configurations for DC / DC converters: half-bridge and full bridge.
• Voltage and current regulation for DC / DC converters.
• Single-phase inverter, PWM control technique.
• Three-phase inverter,  PWM control technique. Principle of current control.

 Applications

• Overview of wind energy conversion systems. Conventional wind energy conversion systems. Power grid connection.
