DC Power Supply: Design, Build, and Presentation (APTE 5601)

This assignment focuses on the design, construction, and presentation of a DC power supply. Students are tasked with researching, designing, and building a DC power supply of their choosing, such as a phone or tablet charger. The project requires detailed documentation, including the purpose, specifications, circuit design, calculations, oscilloscope waveforms under no-load and full-load conditions, and a list of components. Students must create a working model and demonstrate its functionality through video and oscilloscope readings. The final submission includes a professional-grade report or brochure suitable for potential financial backers, incorporating all supporting evidence, revisions, and a statement of originality. The assessment criteria cover various aspects, including cover page, file submissions, program functionality, style, screenshots, descriptions, and adherence to deadlines.

Bachelor of Applied Technology
APTE 5601 Electrical and Electronic Principals.
Assignment 1: DC Power supply.
Final Due Date: Monday 27th June 2016
Other milestone dates as below
Aim:
To demonstrate knowledge, skills and understanding of Digital electronics and integrated
circuit analogue ampliers.
Scenario:
You are wanting to produce your own DC power supply, you need financial support to build
and market the product.
You are to research, design and build a DC power supply of your choosing.
Eg. Phone charger, tablet charger, battery charger, car battery charger, multi voltage DC power
supply.
Your power supply can be 230V supply or 12 V DC supply.
Advance task:
Contact a manufacture and find out how much it would be to mass produce your product and
make a presentation for presenting your product for financial support (like the Dragons Den on
TV)
Material:
Unitec can provide you with most standard electronic components. You will need to provide
the housing (box to put it in) and any specialised item e.g. adaptors or connectors for a phone.
You can use the components in the Technicians room. You may order component via Suresh
our Technician but you need to be aware that it takes a lot of time for items to be delivered.
You MUST build the power supply and not being able to get the necessary components is not
an excuse. These power supplies are yours to take home once marked.

You are to
30th May Provide a document
detailing your power supply.
Include: Purpose (what is it going to do)
Specification: Power in, power out ,voltage and
current.

7th June Provide supporting
documentation for your
working power supply
including calculations and
multisim information
Include: Circuit design, full explanation of
opporation, oscilloscope wave forms with your
circuit working at Full Load and No Load.
Oscilloscope should show wave forms at supply
in, transformer, rectifier, filter, regulator, supply
out. Any where needed to show the similar
depending on your design. You need to also
include the List of Components you need.
25%
13th June Build working model Provide evidence of your bare (no box) working
model. This should be as a video showing what
you have built how it works and performs under
no load and full load conditions. Use an
oscilloscope to show this.
25%
20th June Submit daft report Provide a draft outline of your report, how it will
look and what it will include. Any other
information you require feedback on.
27th June
This date
can not be
extended.
Submit Final Highly
Professional Document. E.g.
Report, Brochure
Your document needs to be of a standard that you
could give to a potential employer or financial
backer. It should have impact and class. It needs to
be presented in colour and beautifully bound.
Your pride or workmanship is important.
Grammer and spelling should be perfect, Layout
and format to a professional standard. You should
include all supporting evidence as submitted
previously and any additional information This
can be as attachments in you make a document
that is not a report otherwise it should be included
in your report. Comment on how your design
differs from your final product, what changes you
made and why.

Statement of Originality: Must be signed and attached with each
submission
I confirm that
This is an original assessment and is entirely my own work.
When I have used ideas, tables, diagrames etc of other writers, I have achknowledged the source in
every case.
This assessment evern thas not previously been submitted as assessed work for an academic course.
