Can someone help me with a simple circuit of an ups? It should have a 5 minutes backup and all parts should be available in the market.
JUST A SIMPLE CIRCUIT.
Is there anyone?
Please write me at upol@glinktel.com for any assisstance.

Ok ...Here it goes..
1:::OUTPUT POWER ---- ~500VA
2:::Battery Voltage----- 12V (7AHr) x 2pcs (Parallel connection to increase power and backup time)
3:::OUTPUT Voltage---- ~230VAC
4:::OUTPUT Frequency-- 50HZ(tolerance 2%)
Here are the requirement...now u can proceed to the next lesson
thanks to u very much
Hi Upol please take a look at this:
**broken link removed**
ITP is asking for a UPS with exact same requirements, so I suggest to
move to one topic so we can assist you both in the design of that UPS,
it seems to me like a school project.
Is it? In this case we have to help you guys with 2 different
designs, yes that's possible by using different ferrite tranformers and
drive circuits.
Hi Upol, can you check in your area for a 500VA transformer with 2x12Volt primary windings that has to be the first close to the core, normal transformers don't work properly because the primary 230 Vac winding is wounded close to the core and secondary is the last winding on top of the primary.
yes...I have a transformer like u described..But one thing...I got a transformer...which's half of the core is for primary and the other half is for the secondary. In such arrangement both the windings have the same distance from the iron core. Will these sort of transformer work?
