D fully coupled output transformer:
Raphaelite has accumulated many years of experience in transformer design and production, and in 2014 introduced an output transformer with extremely complicated structure and manufacturing process. Products
include: single-ended output transformer, and push-pull output transformer two types #. (Some models use single crystal copper winding)
Features of fully coupled output transformer:
Fully coupled means that the secondary winding of the output transformer is 4Ω 8Ω 16Ω, which can realize multi-layer and symmetrical structure all 11 joints with the primary winding, so that the leakage inductance can be controlled to the minimum state under each impedance, completely solving the traditional The 8Ω output transformer has poor sound at the 4Ω output tap and the 16Ω output transformer has poor sound at 8Ω taps or 4Ω taps.
The difference between a fully coupled output transformer and a conventional output transformer winding structure:
The multi-impedance output of the traditional output transformer is generally realized by means of the secondary winding pomelo head. For example, an output transformer of 0Ω-4Ω-8Ω-16Ω, 16Ω is the most complete coupling between the farthest end and the primary winding, but 4Ω. With 8Ω, it is difficult to obtain a fully synchronous coupling with the primary winding if the oil head is used. The uncoupled part will have a different frequency response range from the farthest 16Ω output due to the increased leakage inductance. That is to say, the 4Ω and 8Ω impedance output of the tapping mode is not as good as the 16Ω effect of the remote display from the index and the sense of hearing. (General test indicators are measured by the far-end fully coupled winding impedance) The multi-output impedance of the fully coupled output transformer is realized by the ingenious serial-parallel connection of several secondary windings. There is no tap in this way, and each winding can be coupled with the primary comprehensive symmetry, and the leakage can be achieved under different impedances Minimize. This design can get a 0--4Ω-8Ω-16Ω frequency response basic 1, consistent tone, and lower DC internal resistance!
