i've college assignment to design OFFLINE UPS. Unfortunately we dont have good guidence at college. I'm also eltrx newbie in design.
Plz Suggest some links. Also guide me step by step how to proceed.
Specifications:
1) 500VA
2) o/p= 230 V quassi-square
3) battery:24V, 7.5A backup time: 30 mins.
(from this we can get VA and AHr. rating of battery)
Features/Indicators:
1) Charging
2) Battery starts trickling
3) overload trip indicator (with time condn, should not trip immediately, wait few seconds)
4)MOSFET f/b isolation (whats this ??? :?: )
Plz reply back.
regards,
Neil.
