COMM 3075, College Name: Wireless Portable Mobile Charger Report

This report details the cost analysis and design specifications for a wireless portable mobile charger. The estimated cost is $50, with a focus on minimizing component expenses. Key elements include a converter/step-down transformer, diodes for AC rectification, capacitors, coils, and a magnet. The design emphasizes portability through compact components and an inductive charging pad. The report outlines the voltage conversion process, starting with converting high-strength AC current into lower voltages using a transformer, followed by rectification using diodes to produce fractional DC current, and finally, voltage regulation using a voltage regulator to maintain a stable 5V DC output. The report provides a comprehensive overview of the charger's functionality and design considerations.

Wireless Portable
Mobile Charger

COST
The estimated cost is 50
US Dollars.
Minimum cost has been
allocated for the various
components of the
charger.
The first component is
the converter or step
down transformer that
converts the high
voltage into lower
voltage in traditional
charging devices
Other components are
diodes for rectification
of the Alternate Current
or AC.
Capacitor which charge
till the waveform goes
to its peak and
discharge into Load
circuit when waveform
goes low
Coils
Magnet

PORTABILITY
The size of the device
has been kept small
by including
components that are
small in size.
The device will include
a charging pad which
will feature a closely
joined electromagnetic
inductive charging.

VOLTAGE HANDLING
The first step is to convert
the high strength A.C
current into lower volts
which can be handled by
the device. The transformer
within the charger performs
this particular action.
The next step is the process
of rectification that includes
deducting the negative
fraction of the Alternate
Current therefore the
fractional DC current is
produced at that point.
4 diodes work together in
this regards.
The rectifier that may
perform this task is available
in the commercial shops
which consists of the four
diodes.
However, the most important
device in this function is the
voltage regulator. This is the
component which will
maintain the inflow of
electricity inside the device
at 5V DC.
