ELEC4614 - Power Electronics

A/Prof John Fletcher (Room EE131)

Lab Helpers: Merlin Chai, Nguyen Quang Dai, Ahmed Ahsan, Tan Cheng, Vo Thai Hau

 

 

**********************************************************************

Course History: The undergraduate professional elective course on Power Electronics used to have the course ID : ELEC4240.  From 2007, the course ID was changed to ELEC4614. From 2008, this course has been included in the list of Professional Development courses so that postgraduate students (who previously enrolled in ELEC9240) may take it. Postgraduate students enrolled in this course are now required to take the laboratory component of this course.

Please make sure that you read the ‘Laboratory General Instructions for ELEC4614’ before the lab and have printed out and signed the ‘Laboratory Safety Declaration’ form which you should bring to the first laboratory. If you do not bring it you cannot participate in the laboratory.

 

 

 

1.       Wednesday 7 March 2013

 

Lab schedule added

 

 

2.       Monday 25 March 2013

 

Revised Lab schedule added

 

3.       Laboratory Report requirements

 

 

 

Lab Schedule – A new and improved lab schedule is now available. Please check – I should have allocated to the time slot given to you by the UNSW enrollment system. Please make sure that you read the ‘Laboratory General Instructions for ELEC4614’ before the lab and have printed out and signed the ‘Laboratory Safety Declaration’ form which you should bring to the first laboratory. If you do not bring it you cannot participate in the laboratory.

 

Please also remember there is no lecture on Wednesday morning – I will let you know at the Tuesday lecture if I intend to use the Wednesday session.

 

 

I have changed the lab sequence slightly please check – it only affects Monday afternoon Odd weeks and only the laboratory that you will do, not the time.

 

 

Added tutorial questions.

 

 

Added revised lab schedule with week 8 labs rather than week 12 labs.

 

 

Please read - Laboratory report requirements.

 

 

Added links to lecture material and PPT for next lecture on inverters.
