Core of the Toroidal Output Transformer
A toroidal output transformer has a donut shaped core which is highly efficient. The core is constructed with grain-oriented silicon-iron, and is slit to form a ribbon of steel that is wound like a very tight clock spring. With this type of constructed there is virtually no air gap. With the core being entirely wrapped it allows the output transformer to operate at a higher flux density than a standard transformer. Toroidal transformers can operate at 1.6 to 1.8 Tesla while El cores are limited to 1.2 to 1.4 Tesla.
Efficiency of Toroidal Output Transformers
Efficiency is a measure of a transformer's ability to deliver the input power to the load. The core winding of a toroidal output transformer makes all of the molecules aligned with the direction of the flux. If molecules are not aligned with the flux direction it increases a core's reluctance, which degrades performance to the level of common steel when the molecules are 90 degrees out of phase. Toroidal output transformer can have up to 90 to 95% efficiency while El laminated transformer can be as low as 40% efficiency. In a toroidal output transformer, the standby losses are significantly reduced under no-load operation because of the lower magnetizing currents required by the toroidal core.
In a toroidal output transformer, the efficient use of the core material results in a size and weight reduction of up to 50% allowing it to be used in innovate applications and to be used in enclosed space constraints. The way the toroidal output transformer are construction allows it to have very low levels of noise-inducting stray magnetic field, which makes it a perfect for amplifiers and hi-fi systems and other electronic.
In the past toroidal output transformers has been very expensive and most application could not justify the extra cost. With today's technology in production techniques, it has lowered the cost of toroidal output transformers.
