Dual secondary 266 primary tests
- I am very impressed with the power transfer with dual secondaries, and the associated increase of relative amp turn actions between primary and secondary. A dramatic increase of voltage in vs voltage out is shown on the outer layers of phases 1 & 3 in the 266 pancake coil assembly, each facing their respective secondaries. It is immediately seen that when only the top secondary is in place drawing amperage, the amperages of the three primaries are not reduced significantly, but when the additional bottom secondary is brought into play, this yeilds a significant overall primary amperage reduction, for the same amount of amperage formally found on the top coil, is now split between the coils in an unequal ratio according to their differing amounts of magnetic field issuing from the 266 primary poles, now somewhat tightly coupled with larger turn secondaries providing a voltage rise to the ending loads. However once the secondaries are loaded down by loads, extracting a portion of amperage that would normally circulate in the LC loops, then the dramatic efficiencies are reduced to common examples of power transfer. In fact the incandescent bulbs are probably only 50% efficient.
