BASIC USE AND RUNNING OF UPS IS WRITTEN ABOVE ....
LET ME GIVE SM DETAIL EXPLANATION
UN-INTERRUPTIBLE POWER SUPPLY(UPS)---- HAS BASIC 6 CIRCUITS FOR ITS COMPLETE WORKING
1> MAINS UNDER AND OVER VOLTAGE CUT-OFF CIRCUIT
2> BATTERY CHARGER CIRCUIT
3> RELAY CHANGE OVER CIRCUIT(FROM MAIN TO BATTERY MODE-IN ABSENCE OF UTILITY)
4> BATTERY DEEP CUT OUT CIRCUIT (AT LOW BATTERY THIS CKT WILL CUT OFF BATTERY FROM CKT)
5> INVERTER CONTROL CIRCUT (CONVERTS FROM DC TO AC)
6> POWER OUTPUT STAGE (WITH THE HELP OF TIMER(555),TRANSISTOR AS A SWITCH AND USING MOSFET OR IGBT WITH APPROPRIATE DRIVER TO SWING DIRECT CURRENT TO ALTERNATING AT 180 DEGREE PHASE DIFFERENCE AND PRODUCING 50 HZ FREQ WE CAN DELIVER THE 220 V AC POWER
