I have step down 12-0-12 1Amp transformer input volts 220V and output 12V. As it is step up transformer Np > Ns. I was wondering if I can change it to step up transformer by reversing the input to secondary coil and output at primary coil.
There are 3 wire at secondary coil. how do I connect those wire so that I can use 2 wire as input?(or 12V to both end)
1.step down can change into step up transformer?
2.is there any power loss?(compare to step up transformer,actually I see there is some thin and thick copper wire binding in the transformer. Will this affect the power loss?
update: I have 12V(Two 6V acid lead battery connected in series) I=16A(8A each battery) and i will add some resistor to get I=1A still working on the inverter part for AC current. The load is 9W CFL 100-300VAC.
