Late or Missed Assignments, Reports, or Projects
• Contact the course GA or professor in advance of the
deadline.
• Late assignments will be deducted 10% per day up to 3
days (after which they will receive 0 marks).
• If you miss the midterm or final exam for a medical or
similar reason, appropriate documentation should be
forwarded immediately to the office of the Assoc. Dean
of Engg. Only then, test make-up arrangement can be
taken.

Battery Charging
Renewable Energy from Wind and Solar
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
o An ac/dc converter is shown here
o Converter is a general term
o Converters: rectifier (ac – dc) and inverter (dc – ac)
o Rectifier mode of operation when power from ac to dc
o 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
