There was a time when only very special projects called for the use of a wound transformer component. Back then, due to their complex production needs wound toroidals were in limited supply and this also made them costly. However, technical changes and advances in the manufacturing of wound components has significantly lowered their cost and made them far more accessible option.
Take a Look at the Benefits of Toroidals
A toroidal transformer can be an excellent choice for those looking for high levels of efficiency, low noise, a low stay-flux field and good regulation.
For it’s size and weight the toroidal usually performs much higher than an alternative transformer. With a toroidal core, a close to perfect magnetic circuit is created, thus eradicating the characteristic spaces present in the laminated-bobbin style transformers. This compression of used space results in a comparable component that is generally half the size of a conventional transformer. This can be even higher with custom designed pieces.
This tight magnetic circuit with its uniform distribution of windings is also the reason for the low-noise quality. With a toroidal, it’s not uncommon to experience incredibly low or even zero mechanical noise while in operation. Likewise, toroidals have very low noise-inducing stray magnetic fields. This makes toroidal transformers by Siga and others the transformers of choice for music industry customers.
The tight coupling quality of toroidal winding also ensures that all flux produced by the primary is utilised in the secondary and this results in very low leakage inductance. Good regulation makes toroidals a better performer than laminated stack transformers and means less power is wasted or lost.
Easy and Quick to Use and Mount
Aside from their qualities and specifications, many engineers look to torodials for their ease of use. The majority of models are mounted with just one screw, meaning you save time and reduce auxiliary components. In industrial production this can really pay off.
What’s more, toroidals can be custom made to meet almost any design requirement. Producing units of varying height and diameter, in tall cylinder or flat disc shapes is a relatively standard procedure. This makes them a great choice for anyone seeking to retrofit a toroidal to an already defined space.
With so many uses and applications toroidals are becoming more and more commonplace. Whether standard or custom, they’re positively worth considering.
