Toroidal Transformers, by meeting today's requirements for smaller, more efficient, quieter and safer products, are being accepted in an increasing range of electronic and electrical equipment With toroidal transformer smaller dimensions, lighter weight and low stray magnetic fields , you can build more compact, lower cost quality products without sacrificing performance. Toroidal has a round shape with no air gaps, and with the primary and secondary windings uniformly distributed around the core, locks in\" the magnetic field and makes the toroidal transformer very quiet and efficient. Toroidal transformers are built around a ring-shaped core, which, depending on operating frequency, is made from a long strip of silicon steel or permalloy wound into a coil, powdered iron, or ferrite core.

Advantages of toroidal transformers 1. High efficiency and high performance price ratio Toroidal core has good electromagnetic performance, like high saturation magnetic flux density, high primary inductance and large unit magnetizing power capacity, which improve the utilization ratio of the core and the winding window area, and reduce the number of turns and the direct current resistance, and also greatly improve the overload capacity and load efficiency of the toroidal transformer. Based on these conditions, the product design does not need to consider more power margin and heat dissipation conditions, and also effectively control the cost. 2. Excellent no-load characteristics Toroidal core is wound with high permeability silicon steels, no gap on magnetic circuit, low magnetic resistance. Under the same power and magnetic field density, the no-load loss and exciting current of toroidal transformer are only 50%~70% of other transformers, which reduce the standby loss and improve the equipment operation reliability. 3. Low noise There is no gap of toroidal core, the silicon steels are tightly winded, and after the vacuum impregnation with pressure it becomes a whole. Even in the middle, high magnetic frequency, it will not cause noise due to magnetic expansion. This is what the EI, dry-type and other lamination cores cannot match. 4. Low magnetic flux leakage, low leakage inductance Toroidal core has a high saturation flux density, and the coil is uniformly distributed on the core, magnetic potential difference can effectively reduce the magnetic leakage. Normally, with the same transformer specifications, the magnetic flux leakage of toroidal transformer is only 1/10 of the EI one. The main coil is tightly and rationally layered winded, and then the leakage inductance of the primary and secondary coils can be better coupled to reduce the primary and secondary leakage inductance. 5. Safety of electrical structure There is a certain thickness of stacked dielectric film between the core and primary coils, primary coil and electrostatic shielding, electrostatic shielding and secondary coil, secondary coil and the installation plate, which completely isolates the electrical gap and is safe without maintenance. Therefore, isolated toroidal transformers have been widely used in medical equipment transformers.
The range of toroidal transformers can vary in terms of power capacity, voltage, and mounting style: Power capacity: Standard toroidal isolation transformers can range from 100 to 5,000 VA. Voltage: Dual primaries can be configured for 120 V or 240 V operation. Dual secondaries can range from 2 to 12 V windings to 2 to 120 V windings. Mounting style: Standard mounting for sizes up to 5000 VA is with a single metal centering washer and mounting screw or bolt. Other mounting methods include PCB mounting, DIN rail mounting, and resin center potting with brass inserts. Toroidal transformers are known for their high efficiency, typically ranging from 95% to 99%. This high efficiency is due to their near-ideal design, which effectively contains the magnetic flux within the windings, eliminating leakage flux.
