Working & circuit designing
Power supply unit
Overall view of project
To fulfill the day to day need of mankind we
need to innovate new techniques.
Mobile based appliances controlled system is
evolved to control any kind of electrical
appliances from a significant distance.
Mobile communication technique , DTMF
technology and Micro-controller are used to
configure this project.
Aim of the project-
Controlling electrical appliances by using
mobile by providing signals through DTMF circuit.
Working & circuit designing-
(INTERFACE OF RELAY WITH MICROCONTROLLER)
Power supply unit-
Provides desire DC supply.
Transformer is used to get 12V AC.
Rectifier is used to convert AC to DC.
Regulator eliminates ripple by setting out put to a fixed
Smoothing is performed by large electrolyte
capacitor Connected across DC supply
Unsmooth DC is denoted by dotted line and
smooth DC by solid line
Here a capacitor of 1000uF,400uF,100uF is used
as smoothing ckt.
A rectifier is an electrical device that converts
alternating current (AC), which periodically reverses
direction, to direct current (DC), current that flows in
only one direction, a process known as rectification.
This project can be further enhanced to the
High voltage A.C Applications by changing the
ratings of the Relay.
By this we can control and monitor the high
speed induction motors as well as synchronous
motors. This can be done in an economical
