EC417 - Power Electronics Assignment

Assignment Task

This design assignment is to be carried out in a group up to a maximum of 4 students. A simulation demo session and a single report should be submitted at the end of the semester. Marks will be allocated for the students as a whole based on the assessment rubrics of simulation demo and report. Mark will be deducted for groups with high similarity.

The Assignment

The assignment is to model and simulate AC to DC 5W USB Charger power electronic converter using MATLAB/Simulink Simscape Electrical and compare its performance.

The report should consist of the following sections.

1. Design Methodology

a. Modeling in MATLAB/Simulink Simscape, determine the switching frequency as well as P and I value of the PI controller

b. Repeat the above using PLECS

2. Results and Discussions

a. Analyse and discuss your converter performance including duty cycle, ripple voltage, converter efficiency, thermal analysis and etc.

b. Test your charger with different regions input voltage and frequency around the world.

c. Repeat the above for PLECS and discuss why there are difference.

3. Conclusion

This EC417 – IT and Computer Science has been solved by our PHD Experts at My Uni Paper.
