INTRODUCTION

An Uninterruptible Power Supply / Source,

UPS & battery backup, is an electrical

apparatus that provides emergency power

to a load when the input power supply fails.

PARTS OF UPS

UPS SYSTEM contains the following parts :- • CHARGER CARD• BATTERY• INVERTER CARD• DISPLAY CARD• EMI FILTER• STABLIZER• BUZZER• FAN

.

RECTIFIRE BATTERY

CHARGER CARD:- It consists of a rectifier which converts AC in to DC to charge the Battery.

Input Output Main AC supply DC

It converts the DC into AC.INVERTER CARD:-

BATTERY INVERTERACDC

EMI Filter:-An EMI (Electromagnetic Interference) filter helps to reduce spikes and electrical noise.

INVERTER EMI FilterAC with Noise & spikes

Pure AC

STABLIZER:- Regulates the voltage to the constant range that is safe for the loads.

DISPLAY CARD & BUZZER :-•LEDs are used to indicate the user about the UPS status. Status :- overloading, charging ,online/ offline.

•BUZZER is used to give warnings like: Low battery

Overloading

FAN:-

It is used for the cooling of UPS System.

TYPES

OFFLINE LINE INTERACTIVE ONLINE

OFF LINE UPS

The mains to battery changeover time or battery

to mains changeover time is very low as

compared to inverter.

Changeover time in inverter is 500 msec.

Offline UPS has changeover time of 3-8 msec.

DIAGRAM OF OFF LINE UPS

Offline UPS are normal weight UPS and are widely used for domestic Purpose.

ON LINE UPS

On line UPS always remains on battery, whether input

supply (AC) is present or not.

When mains supply (AC) is present, it provides power to

DC supply of inverter section & charges the battery bank

conjointly.

When mains supply (AC) is not present, it will run the connected

load to the battery bank.

DIAGRAM OF ON LINE UPS

LINE INTERACTIVE UPS

The battery to power converter / inverter is

always connected to the o/p of the UPS.

When the input supply (AC) fails, transfer

switch opens and then the inverter starts

functioning to load immediately.

DIAGRAM OF LINE INTERACTIVE UPS

APPLICATIONS:-

UPS generally used , where data loss causes a serious problem like in:-

• Computers• Operation Theaters• Banks • Control Room applications

DIFFERENCE B/W UPS & INVERTER

UPS• It has high switching speed

& very low switchover time(2 to 4 ms).

• It is used for computer applications.

• Output is sine wave.

INVERTER• It has low switching speed

& high switch over time (20 to 40 ms)

• It is used for home appliances like TV , Fan , Tube-light etc.

• Output is square wave.

ENERGY CONSERVATION

AGENDA

WHAT IS ENERGY? TYPES OF ENERGY WHY TO CONSERVE? WHAT CAN WE DO? ENERGY CONSERVATION IN INDIA

RENEWABLE ENERGY:

Renewable energy can be generated

continuously practically without

decay of source

Solar energy , Wind energy , Geothermal

energy , Hydro energy

NON-RENEWABLE

ENERGY:

Non-renewable energy is energy that comes from

the ground and is not replaced in a relatively short amount of time.

e.g. energy generated from combustion of fossil fuels , coal ,

gas etc.

WHAT IS ENERGY ?

Energy lights our cities, powers our vehicles, and runs machinery in factories. It warms and cools our homes, cooks our food, plays our music, and gives us pictures on television. Energy is defined as the ability or the capacity to do work.

WHY TO CONSERVE IT ?

We have limited resources available on earth. Our demands are continuously increasing day by day. It is possible that someday most of the non-renewable resources will be exhausted and we will have to switch over to alternate energy

Limited Fuels• At present consumption levels-• Crude oil will last only for 40

years.• Gas will last for 60 years.• Coal will be finished in nearly

200 years.

• Ever thought of life without oil and gas?

We save our money when we save energy.

We reduce pollution when we save energy.

We save our energy when we save energy.

WHAT WE CAN DO ?

RECYCLE - compositing waste materials into new products to prevent waste of potentially useful materials. Turn off all electronic devices that are not in use. Not only turn them off but try to remember to unplug them. You will be surprised how much you will save with this simple step! Replace old light bulbs with energy saving fluorescent bulbs. They may cost more, but will save you much more in the long run.

At Home•We should not keep lights unnecessarily switched on.• Reduce the energy your appliances consume by analyzing star ratings.• Improve your water heating efficiency to reduce energy costs.

At Public Places

• Switch of the fans and lights in the places like bus terminal and railway stations when not necessary.• Switch off the street lights.• Big Hoardings, lightened up for the whole evening and nights are other wastage of power which can be and should be avoided

HOW WILL IT HELP ?

Let’s Take an simple example

• Power saved: 100W-13W = 87W=87W X 6 Hours X 365 Days=17520 WH=17.520 kWH or Units=Rs. 52.56

Say Rupees 50 per one bulb replaced.

We replace one 100W bulb with a 13W CFL and assume electricity is available for Rs. 3.00 per unit. and this bulb is used for 6 Hours a day.

ENERGYCONSERVATION IN INDIA

About 70% of India's energy generation capacity is from fossil fuels, with coal accounting for 40% of India's total energy consumption followed by crude oil and natural gas at 24% and 6% respectively. India is largely dependent on fossil fuel imports to meet its energy demands. By 2030, India's dependence on energy imports is expected to exceed 53% of the country's total energy consumption. In 2009-10, the country imported 159.26 million tonnes of crude oil which amount to 80% of its domestic crude oil consumption and 31% of the country's total imports are oil imports. The growth of electricity generation in India has been hindered by domestic coal shortages[ and as a consequence, India's coal imports for electricity generation increased by 18% in 2010
