Why do so many engineers and manufacturers turn to toroidal transformers? Simply put, these small devices are robust and consistent. These simplistic devices are considered powered transformers that are constructed from a toroidal core that has primary and secondary coils uniformly wound around the entire core. As electrical currents flow through the primary coil, EMF gets induced as well as a current in the secondary winding. The unique shape of these coils allows for substantial reductions in winding and resistive losses, which improves the overall efficiency of the toroid.Read More
