Project’s Steps and Testing

The

most

important

thing

to

be

considered

in

determining

the

water

flow

to

inlet

of

the

transducer

is

how

much

input

power

could

inter

to

the

turbine

blades
.


Pin=Q*H*g



The goal of the electronic circuit is to increase the
voltage that comes from the generator to a specified
value (i.e.
1.5
v).

The generator will produce AC Voltage.

AC/DC converter.





It is a step
-
down DC to DC converter.

It

is

a

switched
-
mode

power

supply

that

uses

two

switches

(a

transistor

and

a

diode)

and

an

inductor

and

a

capacitor
.

Battery

charger

is

a

device

used

to

put

energy

into

a

secondary

cell

or

(rechargeable)

battery

by

forcing

an

electric

current

through

it
.



The charger has three key functions:

I.
Getting

the

charge

into

the

battery

(charging)
.

II.
Optimizing

the

charging

rate

(stabilizing)
.

III.
Knowing

when

to

stop

(Terminating)
.





Find

an

environmental

design

that

co
uld

harvest

the

energy

of

water

flow

in

the

tap

for

charging

the

batteries
.


Use

the

remaining

output

current

to

switch

on

a

small

light

bulb

Micro

turbine

generator
:

The

wasted

water

from

tap

flows

through

it
.

Turbine
:

is

responsible

to

change

the

energy

of

the

water

to

mechanical

energy
.

Gear

box
:

is

responsible

to

increase

the

velocity

of

the

rotor

to

produce

more

flux

in

the

generator

side

which

will

increase

the

efficiency

of

the

unit

Used to simulate the electronic circuit to produce DC
voltage which will be used to charge a battery

It

used

to

create

the

PCB

of

the

electronic

circuit

The input power and output power from the micro
turbine generator was calculated as follow:

Water Density (ρ) at

Gravitational Acceleration (g )

9.81 m/s2

Height (H)

8 m

Flow Rate (Q) measured

7 L/min

Input Power

9.156 W

P

= η * P
in


= 50% * 9.156


= 4.578 W









For frequency change between 40 Hz and 60
Hz, the variation of

was:








The main purpose of the software:


Determine the output voltage from the circuit (
1.5
V).

Verify the output currents from the bridge of diodes, inductors and
the switch transistor ( choose
components).














Output voltage of the electronic circuit

Diode current

Transistor current

Depending on the current waveforms the following
components were chosen for the electronic circuit:


Diode SB5100

Power inductor FIT106

Power transistor IRLB3036

Triggering chip IRS21864

Capacitance with high voltage capability


























The schematic of electronic circuit board

Accept

responsibility

in

making

decisions

consistent

with

the

safety,

health

and

welfare

of

the

public
.


Be honest and realistic in stating claims .


Improve

the

understanding

of

technology,

its

appropriate

application,

and

potential

consequences
.

The project objectives were completely achieved.


This design is a solution for the environment to reduce
the pollution produced from Fossil fuels.


Improving the project by:

1.
Changing the place of the system.

2.
Using coin battery .



Designing the electronic circuit using
OrCAD

software .(some of
the components don’t have footprints in the
OrCAD

layout).


Using

the

DipTrace

software

to

create

our

own

footprints
.


Testing of the electronic circuits on the bread board; the result
doesn’t appear.
