Hi, i am working on project that needs to belong to the lightweight division, so i was wondering if i could dismantle the E-I Transformer i have, with that i say, take off the laminations and mount it on the PCB with just the plastic that the copper wire is envolved, by doing that it almost weights nothing. My question is, if i take the laminations off, what would this cause to transformer and circuit?
Another question, i want to match two transformers in parallel operation, to do that i am thinking of ensuring the same voltage at no load, this will also match the impedance right ? Because, if the voltages are the same, there will be no circulating induced current on the secondary circuit and the if the impedance is the same, the load they will share will also be the same, right ? Or there are other parameters to consider, like the size of the copper wire that each transformer has, or going even further, the voltage is produced with turn ratios, so they could be producing both 15.7 but with different impedances.
So i have a transformer with 17.8VAC at no load and another one with 15.7VAC at no load, they are both from the same manufacturer, they are almost the same thing, both rated for 15VAC( I know, i know, 17.8VAC rated for 15? State-of-the-art manufacturers). To easier way is to reduce the 17.8VAC to 15.7VAC as i see, them i just need to remove secondary turns on the 17.8 transformer ?
