CE 1.2 Project Background
CE 1.2.1 Characteristics of the project
A power inverter can be defined as the specific electronic device, which changes the
DC or direct current to the AC or alternating current. The output voltage, output frequency,
total power handling and the input voltage is completely dependent on the designing of the
circuitry or device. I have designed a power converter for converting DC to AC. Furthermore,
I even focused on the method of converting lower voltage of DC power to the higher voltage
of DC source with the help of PWM or pulse width modulation. The outcome of the method
was analyzed for further checking as well as analysis. The main result of this project was to
obtain two different forms of AC outputs, which are pure sine wave and modified sine wave.
I have seen the modified sine wave as maximum of the square wave than the sine wave.
Moreover, I used the transformer that can easily boost up the voltage up to 220 volts. Hence,
in the project, I have significantly developed the compact and complete design of DC to AC
power converter and hence evaluated the efficiency of the desired outcome.

CE 1.2.2 Objectives developed for the project
During the project of Design and Fabrication of DC to AC Power Converter, the
entire designing part required higher constants that can easily reduce the effectiveness and
operation. I have even found out the fact that the utilization of higher dielectric constants can
subsequently provide a narrow bandwidth. Thus, in the project my objective was to develop a
design while making the significant trade off within the conversions from DC to AC.
Therefore, for completing this project with higher efficiency as well as priority, I have
successfully developed the following objectives:
 To review and analyze several methods of conversions that is efficient.
 To propose an appropriate design for the DC to AC converter.
 To check the different forms of outputs of sine waves.
 To review the output and check with the desired outcome.
 To use the transformer for boosting up voltage of 220 volts.
CE 1.2.3 My area of work
Since, during this project work I had experience in field work; I was appointed as the
chief electrical engineer. I had been working as a team member under the proper guidance of
my team leader. I had to help my other team members in this particular project. Before
starting the work in this project, I have researched about the converter that helps to convert
direct current to alternating current. The practical part of the project was started only after
studying and reviewing the past studies based on DC to AC power converter for
understanding and evaluating the properties and characteristics. My major area of work was
simply to convert the lower DC power voltage to the respective higher DC source voltage.
My other important areas of work were to participate within the usage as well as
advancement of the complete computerized and digitalized management system. I even
directed the design department to prepare the detailed drawings and requirement drawings.

My major segment was related to commercial kitchen equipment. I selected oven for this
purpose. The complete installation as well as implementation of the oven was done by me
and I even monitored and checked the quality of materials. I was also recruited as the
assistant of my team leader.

CE 1.2.5 My responsibilities throughout the project
In this project, as a chief electrical engineer, I had to undergo various electrical works
with my team members and team leader. My first responsibility was performing the electrical
maintenance work, wherever required after involving the important repair to all the higher
line MEP infrastructures and utilities. I even installed, altered, maintained and finally
repaired the electrical wiring system and equipment. As the chief electrical engineer, I also
prepared and presented several sketches to show the locations of equipment or wirings. Since,
I was executing the project related to kitchen equipment; I had to note down the wave forms
on the basis of input current and voltage and finally match them with the desired output
