CONTROL OF CURRENT SOURCE
CONVERTER FED REVERSING
INDUCTION MOTOR DRIVE BY
REMOTE CONTROL.
ABSTRACT
• The microcontroller receives the Infrared Signal from the TV
remote, the code of which is identified by the IR receiver
depending on which it switches ON/OFF the appropriate relay
or TRIAC for a split phase induction motor to achieve desired
direction.
• The Range of the system is up to 10 meters. The project can
also be used to switch ON/OFF electrical devices of maximum
load current of 5A by minor alteration.

EMBEDDED SYSTEMS
Definition for :-
EMBEDDED SYSTEMS
 A combination of hardware and software which together
form a component of a larger machine.
 An example of an embedded system is a microprocessor that
controls an automobile engine.
 An embedded system is designed to run on its own without
human intervention, and may be required to respond to
events in real time.

LED
LEDs are semiconductor devices are made out of silicon
When current passes through the LED, it emits photons as a
byproduct. Normal light bulbs produce light by heating a metal
filament until its white hot
LEDs present many advantages over traditional light sources
including lower energy consumption, longer lifetime,
improved robustness, smaller size and faster switching
TSOP 1738 RECEIVER PIN DIAGRAM
 It’s a standard IR remote control
receiver
 supporting all major transmission codes
 Pin1 – Connected to Ground
 Pin2 – Connected to Vcc
 Pin3 – Output Pin
 In Between 1st Pin and 2nd Pin we have
to connect one Capacitor
 TSOP 1738 Receives 14—bit of data
TSOP 1738 FEATURES
•
Photo detector and preamplifier in one package
•
Internal filter for PCM frequency
•
TTL and CMOS compatibility
•
Output active low
•
Low power consumption
•
High immunity against ambient light
•
Continuous data transmission possible (up to 2400 bps)
• Suitable burst length .10 cycles/burst
RELAY
IT IS A ELECTRO MAGNETIC SWITCH
USED TO CONTROL THE ELECTRICAL DEVICES
COPPER CORE MAGNETIC FLUX PLAYS MAIN ROLE HERE
Relay Driver ULN2003
 ULN is Relay driver application
 The ULN2003 is a monolithic high voltage and high current
Darlington transistor arrays.
 It consists of seven NPN Darlington pairs that features high-voltage
outputs with common-cathode clamp diode for switching inductive
loads.
 The collector-current rating of a single Darlington pair is 500mA.
 The Darlington pairs may be paralleled for higher current capability.
Contd …
• The ULN functions
as an inverter.
• If the logic at input
1B is high then the
output at its
corresponding pin
1C will be low.
