The document discusses uninterruptible power supplies (UPS). It defines a UPS as a critical device that provides emergency backup power when the primary power source fails. A UPS contains components like an AC to DC converter, batteries, inverter, and battery charging unit to regulate voltage and provide continuous power. UPS systems are used to protect equipment from power disturbances that can cause data loss or equipment damage. The document outlines the components and functions of a basic UPS.

4. INTRODUCTION
AFTER COMPLETION OF THIS PRESENTATION A STUDENT
WILL BE ABLE TO UNDERSTAND:
4

5. DEFINE UNINTERRUPTIBLE POWER SUPPLY?
• AN UNINTERRUPTIBLE POWER SUPPLY (UPS) IS A CRITCAL DEVICE
(INHOMES,COMPANY,SITES) THAT HAS AN ALTERNATE SOURCE OF
ENERGY THAT CAN PROVIDE EMERGENCY POWER WHEN THE
PRIMARY POWER SOURCE IS TEMPORARILY DISABLED

6. WHAT THE ALTERNATE NAMES OF UPS
 UPS SYSTEM
 UNINTERRUPTIBLE POWER SUPPLY SYSTEM
 UNINTERRUPTIBLE POWER SOURCE SYSTEM
 BATTERY BACKUP SYSTEM

7. WHY WE USE A UPS?
• PROTECTS AGAINST MULTIPLE TYPES OF POWER
DISTURBANCES
• ONLY DEVICE THAT PROTECTS IS UPS
• OFFERS PROTECTION AGAINST
COMPUTER AND EQUIPMENT DAMAGE
DATA LOSS,BUT DUE TO UPS IT MAY BE SAVED

8. CAUSES OF POWER DISTURBANCES
• STORM ACTIVITY – LIGHTNING, WIND, ICE
• OBJECTS COMING IN CONTACT WITH POWER LINE AND
TRIPPING BREAKER – TREE BRANCHES, ANIMALS, OTHER
• CONSTRUCTION ACTIVITY
• ACCIDENTS – MOTOR VEHICLE, OTHER
• EQUIPMENT FAILURE
• OVER LOADING
• NON-LINEAR LOADS
• POOR GROUNDING

9. CAVITATION

12. PROBLEMS RESULTING FROM POWER DISTURBANCES
• DATA ERRORS
• DATA LOSS
• BLOWN FUSES
• TRIPPED BREAKERS
• OVERLOADED NEUTRAL CONDUCTORS
• MOTORS
 HEATING
 SPEED VARIATION
 VIBRATION
• TRANSFORMERS
 HEATING
 AUDIBLE NOISE

14. UPS COMPONENTS
14
 AC TO DC CONVERTER
 BATTERY
 INVERTER
 BATTEY CHARGING UNIT
 SOFTWERE CONTROL
 SWITCHES

15. CONVERTER - AC TO DC
PROTECTS AGAINST SPIKES AND TRANSIENTS
WE USE IT IN DAILY LIFE TO CHARGE,CAR BUS BATTERIES

16. BATTERY
ENERGY STORING DEVICES
CONVERT CHEMICAL ENERGY TO ELECTRICAL ENERGY

17. INVERTER – DC TO AC
VOLTAGE REGULATOR – PROTECTS AGAINST SAGS, SURGES AND
FLUCTUATIONS

18. BATTERY CHARGING UNIT
VOLTAGE REGULATOR
RESPONSIBLE TO BATTERY CHARGING
PROTECT OVER CHARGING

19. MONITOR AND CONTROL HARDWARE / SOFTWARE
 Control all the operation of UPS

20. CAVITATION
• Cavitation is the formation of bubbles or cavities
in liquid, developed in areas of relatively low
pressure around an impeller. The collapsing of
these bubbles trigger intense shockwaves inside
the pump, causing significant damage to the
impeller and/or the pump.

21. GENERAL DISCUSSION
21
• DOES A UPS OFFER COMPLETE PROTECTION?
• DO YOU THINK “POWER DISTURBANCES WON’T HAPPEN TO YOU”
?

22. DOES A UPS OFFER COMPLETE PROTECTION?
22
• SOME POWER DISTURBANCES MAY EXCEED THE
HANDLING CAPABILITY OF THE UPS.
• UPS FAILURE

23. DO YOU THINK “POWER DISTURBANCES WON’T HAPPEN
TO YOU” ?
23
• POWER DISTURBANCES OCCUR FREQUENTLY, THOUGH MANY
ARE SMALL AND WITH OUT CONSEQUENCE
• AN ON-LINE UPS CAN PROTECT AGAINST MORE SIGNIFICANT
POWER DISTURBANCES WHEN THEY DO OCCUR

24. RECAPITULATION
THINGS TO CONSIDER WHEN SPECIFYING A UPS
24
• POWER QUALITY
 ARCHITECTURE - LINE INTERACTIVE OR ON-LINE
 IMMUNITY TO DISTURBANCES OTHER THAN OUTAGE
• RUN TIME
• RELIABILITY
• AUDIBLE NOISE
• MONITOR AND CONTROL HARDWARE / SOFTWARE
 LOCAL / REMOTE CONTROL
• INITIAL COST
• MAINTENANCE COST
• WARRANTY

26. ?
CAN WE STORE THE ELECTRICITY EASILY?

27. YES
WE STORE IT ONLY MEANS TILL NOW ARE
BATTERIES SO THE BATTERIES ARE MAJOR
COMPONENTS TO STORE ELECTRICTY

28. BATTERY
 STORE ENERGY
 CONSISTING ONE OR MORE CELLS
 TWO ELECTRODES
 POSITIVE TERMINAL, ANODE,
 NEGATIVE TERMINAL, CATHODE
 CHANGE ELECTROCHEMICAL ENERGY TO
ELECTRICAL ENERGY

29. CONCLUSION
Dear student today we discuss about UPS
WHAT IS UPS?
DEFINE UNINTERRUPTIBLE POWER
SUPPLY?
WHAT IS THE ALTERNATE NAME OF UPS?
WHY USE A UPS?
UPS COMPONENTS
Tomorrow we shall discuss about Solar System.
