EXTREMELY URGENT TASK:

Masters Level Report on "Performance of single phase full wave rectifier controlled by PWM"

13 single spaced pages; 550 words per page; with Title Page, Outline and Reference List.

UK English

Harvard Referencing

Deadline: As soon as possible.

Task::

Semiconductor switching devices produce significant

harmonic voltages as they chop voltage waveform during the

transition between conducting and cutoff stages. Therefore, the main objectives of this report are as follow;

1-PWM switching technique

is proposed to shift the low-order harmonics to higher

frequencies away from the fundamental to be easily filtered.

2-Chopping technique is the control method that will be applied

to shape the output waveform so the output voltage

of the bridge rectifier will be “chopped” in a sequential

manner with a certain number of pulses and duty cycle to

control the flow of current through the [url removed, login to view] it will be used to devolve

the mathematical model.

3-MATHMATICAL MODLING to calculate the coefficients of Fourier series.

4-Calculation of the AC components(harmonics)of the output voltage for both controlled and uncontrolled rectifiers.

Note that additional materials will be provided:

1-papers to explain briefly my project.

2-schematic diagrams for both the controlled and uncontrolled rectifier.

3-A sample of report structure.
