HI
I AM HAVING FEW PROBLEMS IN MAKING UPS CIRCUIT.
THERE ARE 2 SECTIONS OF IT
1...CHARGING SECTION
2...INVERTER SECTION
1,,,,,,,,,,,,,,FOR CHARGING SECTION I HAVE USED PWM TECHNIQUE BY GENERATING
A RAMP OF MY DSIRED LEVEL AND THEN COMPARING TO THE BATTERY
VOLTAGE LEVEL,THUS PROVIDING APPROPRIATE TRIGGER PULSE FOR SCR THAT CHARGES BATTERY
THROUGH A BRIGE AND CAPACITOR.
NOW REMEMBER THAT I AM USING 12 V 4 A BATTERY NORMALLY USED IN MOTORBIKIES.
NOW BATTERY IS CHARGED WHEN SCR IS TRIGGERED AND THROUGH CAPACITOR WHICH IS CHARGED
BY PULSATIND DC FROM BRIDGE..
NOW MY QUESTION IS WILL SCR BE OFF AFTER BATTERY IS FULLY CHRAGED BY COMPARISION OF
BATTERY VOLTAGE AND CAPACITOR VOLATGE ON CATHODE AND ANODE CATHODE OF SCR RESPECTIVELY..
2,,,,,,,,,SECOND I AM MAKING INVERTER USING MOSFET BRIDE TECHNIQUE,
NOW MY CIRCUIT IS RUNNING WITH NORMAL LAB BATTERY SUPPLY BUT NOT WITH BATTERY
I AM USING FOR PROJECT THAT 12V 4 A
IT TENDS TO CREATE A PROBLEM WHEN IT IS COUPLED WITH THAT BATTEY,,
PLEASE DO REPLY ON THIS ,AND SORRY I CAN'T POST U THE LAYOUT OF THE CIRCUIT ,
