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

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
