- 2. Title and Introduction
SIMULATION BASED IMPLEMENTATION OF DC-DC BOOST CONVERTOR
USING FUZZY LOGIC CONTROLLER TO ENHANCE THE TEACHING AND
LEARNING OF POWER ELECTRONICS COURSE.
Introduction:
The purpose of designing and development of multifunctional PIC microcontroller based trainer is
to design such embedded system trainers which have different functions modules to be used for
teaching and learning on one board.
It will help the students of engineering and technical education to get in depth knowledge and
practical hands on experience about programming and implementation of PIC microcontroller in
various embedded systems applications.
On very affordable price, students may even place this trainer board in their home made labs
especially for technical education students trainings ,the trainer to be developed would support the
good process of learning.
This PIC trainer consist of ten on-board embedded modules including main board and
programmer, and experimental Lab manuals for all embedded modules.

- 3. Problem Statement
The current curricular in technical universities and institutions are more theoretical
rather than technical hands-on based, thus producing graduates who are unable to
meet the ever-rising demand of industry for skilled engineers.
The employment cost is ultimately increased, as the employers have to spend extra
on providing the required training.
The emphasis in the light of education policy is to have more hands-on practical
rather than academic.
The price range for fully equipped workstations that comes complete with
microprocessor or microcontroller training kits is very high and also additional costs
such as maintenance of the board should be taken into account.
This contributes to the limited number of boards and the ratio of available board to
the students in the lab come to be very high – 1:2 or 1:3, which may depreciate the
effectiveness of the teaching and learning process, consequently, the time taken to
complete the whole syllabus will lengthen and probably the objective of the module
taught will not be achieved.
Most of the technical courses are being taught by using modules, that are prepared
by vendors with mostly low academic background. Hence, such modules are
produced with fixed features and usually have constraints in adapting to the
changing needs of a technical institution.

- 5. Scope and Limitation
PIC Trainer to be developed should support the decent process of
learning and teaching, students can also bring this trainer from their labs
and continue work at their own places.
This project serves as a fundamental for the students to indulge actively
in the development of embedded system
It is intended that the module designed should be free from any
firmware, meaning that it should be open to any program and configuration
without having any firmware that could interfere with user programs.
The best thing is that the development of the programs, compiling, and
then the simulations are all carried out with the freely available software
tool Microchip MPLAB.
PIC Education Trainer for students is the best way to help the students
improve their skills and in the meantime reducing the cost for universities.

- 6. Theoretical Framework
The theoretical framework that will be used in the study is the InputProcess-Output Model. In the IPO model, a process is viewed as a
series of boxes (processing elements) connected by inputs and
outputs. Information or material objects flow through a series of tasks
or activities based on a set of rules or decision points.

- 7. Operational Definition
There are many steps involved in the design and development of this
training panel. The panel includes, one main PIC board which is
integrated with various multi-functional embedded system modules.
All the modules are prototyped, PIC Simulator IDE is used to simulate
the interface between the target microcontroller and certain available
module . Then, modules are also constructed on a breadboard and
tested. The successful modules are then prototyped on a printed circuit
board. Finally all the modules together with its running board are
integrated and tested for their functionality.
PIC microcontroller main board is the heart of this panel. It acts as the
main processing units for all inputs and outputs. Various multifunctional embedded system modules are being controlled using Clanguage programming which is downloaded in the microcontroller.
The modules are multi-functional and hence they are flexible in their
operation, which can be modified using programming.

- 8. LITERATURE REVIEW
Hardware component's of PIC Microcontrollers:
PIC microcontroller production counts are in the billions per year, and the controllers
are integrated into many appliances we have grown used to, like household appliances
telecommunication, automotive industry, aerospace industry, industrial automation.
hardware can be classified as input or output. Inputs range from simple switches to
complex analog sensors which measure physical values and (ultimately) convert them
into a corresponding voltage. Outputs encompass primitive LEDs as well as
sophisticated actuators.
Switch/Button : The button is one of the simplest input elements. It consists of two
contacts which are connected if the button is pressed. So if one of the contacts is
connected to for example GND and the other is connected to the microcontroller input
and to VCC through a pull-up resistor (either internally by the microcontroller.
Matrix Keypad: The matrix keypad consists of several buttons which are arranged in a
matrix array.
Potentiometer: The potentiometer is a variable voltage divider. It has three pins: Two
for the input voltages Ua and Ub, one for the output voltage Uz. Depending on the
position of a turning knob, Uz is somewhere within [min{Ua, Ub}, max{Ua, Ub}]. The
correlation between the position of the knob and Uz can be either linear or logarithmic.

Hardware component's of PIC Microcontrollers:
LED: The LED (light emitting diode) is the most basic output element. Its form and
color vary widely to accommodate a wide variety of applications. The color of a LED is
determined by the chemicals used for it. Common colors are red and green, but
yellow, orange, blue and white LEDs are also readily available, as well as LEDs emitting
light in the infrared or ultraviolet bands.
Numerical display: A seven-segment display (SSD), or seven-segment indicator, is a
form of electronic display device for displaying decimal numerals that is an alternative
to the more complex dot-matrix displays. Seven-segment displays are widely used in
digital clocks, electronic meters, and other electronic devices for displaying numerical
information.
Motors: Electric motors use electric energy to achieve a rotary motion. There are two
basic principles which are used to create rotary motion in electric motors: the Lorentz
force and magnetic attraction.
DC Motor: DC motors use DC voltage to achieve rotary motion. They have two pins
with which to control the speed and direction of their rotary motion.
A stepper motor is a brushless, synchronous electric motor that converts digital
pulses into mechanical shaft rotation. Every revolution of the stepper motor is divided
into a discrete number of steps, in many cases 200 steps, and the motor must be sent a
separate pulse for each step.

- 10. PIC Based: The main advantages of using the PIC are low external part
count, a wide range of chip sizes (now from 5-pin up!) available, nice
choice of compilers (assembly, C++, BASIC, etc.) good wealth of
example/tutorial source code and easy programming. Once bought, the
PIC's program memory is empty, and needs to be programmed with code
(usually HEX files) to be usable in a circuit. Those trainers they controller
by PIC architecture they have very good outcomes and results because
they are very efficient for educational and training on-board modules.
PID Based:
The basic function of a controller is to execute an
algorithm (electronic controller) based on the control engineer's input
(tuning constants), the operators desired operating value (set point) and
the current plant process value. They are expensive trainers and only
cover some specific operation and not interface with any module.
PLC Based:
PLCs based trainers are used in many industries and
machines. Unlike general-purpose computers, the PLC is designed for
multiple inputs and output arrangements, extended temperature
ranges, immunity to electrical noise, and resistance to vibration and
impact. These trainers are used for industrial robotics and automation.
Microcontrollers: Microcontrollers may use four-bit words and
operate at clock rate frequencies as low as 4 kHz, for low power
consumption. They will generally have the ability to retain functionality
while waiting for an event such as a button press or other interrupt;
power consumption while sleeping may be just Nano watts, making
many of them well suited for long lasting battery applications. Other
microcontrollers may serve performance-critical roles, where they may
need to act more like a digital signal processor (DSP), with higher clock

- 13. Methodology
The selected modules designed should come with open input/output
that are free to be interfaced or ported to any type of microcontrollers.
But, due to simplicity, only few microcontrollers are chosen
PIC16F84A and PIC16F877.
Before all the modules are prototyped, PIC Simulator IDE Version
5.22 is used to simulate the interface between the target
microcontroller and certain available modules. The modules are also
constructed on a breadboard and tested.
The successful modules are then prototyped on a printed circuit board.
Finally all the modules together with its running board are integrated
and tested for their functionality.
