CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
The single phase bridge DC to AC inverter could be properly designed only after
considering few assumptions and conventions. This single phase full bridge inverter is
responsible for producing the square-shaped output voltages for a single-phase load. While
executing this project, I provided a better performance of a single phase full bridge inverter
with the resistive load. I used Multisim software for simulating and improving the power
inverter device. Moreover, I have used the duty-cycle based configurations of LM555 timer
for generating the AC outputs of 50Hz. Two distinct BJT transistors of NPN and PNP were
also utilized for converting the 12 V DC to 24 AC cycle. I selected a low-pass filter for
testing and transforming distorted square wave into pure sinusoidal wave. Therefore, I have
executed the project with proper standards by providing a complete design of single phase
full bridge inverter.

CE 2.2.2 Objectives developed for the project
The single phase full bridge inverter is the significant electronic device that
transforms the DC to AC. I had to follow a set of standards for getting the perfect and desired
outcome. There were a couple of activities that were required to be executed properly. I have
used single phase uncontrolled rectifiers for a number of power electronic based converters. I
wanted to improve the inherent limitations of a power inverter and therefore, in order to
complete my project and generating power by designing a single phase full bridge inverter, I
have developed the following objectives:
 To propose the design of a single-phase full bridge inverter with all necessary
components as well as items.
 To improve or remove the inherent limitations of a power inverter.
 To utilize the software of Multisim for simulating and improving the power inverter
device.
 To use effective ways for estimating the drop in voltage within the circuitry with the
facility design.
 To have familiarity with DC to AC inverter design and single phase half bridge
inverter.
CE 2.2.3 My area of work
I was appointed as the chief electronics and communication engineer in this project. I
had experience in the field work due to my previous involvement in few projects and this I
had the core responsibility of designing the entire single phase full bridge inverter. I was
responsible for identifying the components required to design this inverter and provider
proper guidance to my team leader and head of the departments. Being, the chief electronics
and communication engineer, I was supposed to make the circuit diagram and even

implement the circuit. Moreover, I had submitted weekly progress reports to my project
leader and head of the department.

CE 2.2.5 My responsibilities throughout the project
In the project of Single Phase Full Bridge Inverter, I was assigned for proposing a
compact design for the single-phase full bridge inverter. For this purpose, I had to use the
various non linear control techniques, which are used in the pulse width modulation inverters.
I had to ensure that the sliding mode control offers robustness against external disturbances
and parameter variations. Moreover, I even used my intellect for solving the issues faced in
this project. My other responsibility was to use Multisim software for implementing the
circuit of this single-phase full bridge inverter properly. I also had to consider the full-bridge
voltage source inverters with the resistive load. The circuit was being operated by simply
switching 4 switches, S1, S2, S3 as well as S4 and these four switches were switched on and
