Can any body present here may help me in understanding and making a UPS based on SMPS AC to DC converter so that there will be no need of any type of transformer and the UPS would not be bulky and heavy. It should handle be capable of handling atleast 500Watts of Power.
hi for this request U should use
SG3225 or tl494 or tl598 circuit these are the best chip for smps work
(note: in which case U should use transformer but with smps it's can be little & more light )
