Application of Power Electronic Systems Battery Charging Renewable Energy from Wind Uninterruptible Power Supplies (UPSs) DC and Induction Motor Drives: A motor drive consists of An electric motor A power electronic converter And possibly a speed and/or position sensor Applications Servo motor drives in robotics Variable-speed drive for adjusting flow rates in pumps

SET Forms Student Evaluation of Teaching forms will be administered during the last two weeks of the class.

Scope and Applications

Power Flow through Converters An ac/dc converter is shown here Converter is a general term Converters: rectifier (ac – dc) and inverter (dc – ac) Rectifier mode of operation when power from ac to dc Inverter mode of operation when power from ac to dc

Power Processor as a Combination of Converters A converter is a basic module or building block of a power electronic system Converters: rectifier (ac – dc) and inverter (dc – ac) Energy storage elements (inductors and capacitors): decouple the input and the output sides

AC Motor Drives Converter 1 rectifies line-frequency ac into dc Capacitor acts as a filter; stores energy; decouples Converter 2 synthesizes low-frequency ac to motor
