6.  Review of Ultrcapacitors ◦ Physical construction and operation of ultrcapacitors ◦ Application of ultracapacitors in energy storage for automotives and renewable energy sytems ◦ Electrical characteristics and equivalent circuits of ultracapacitors 

7.  DC-DC Converter ◦ Select and design a dc-dc converter to charge the ultrcapacitor from a small 12 V battery (size the battery for the application) ◦ Select a dc motor with high starting current for the application ◦ Simulate the converter in PSICE ◦ Use MATLAB/Simulink to model the complete system 

8.  Demonstrate the application with the battery, ultracapacitor, dc-dc converter and motor ◦ Identify the parameters that would be important in optimising the overall system ◦ Build and test the complete system
