A toroidal transformer is known to be one the highest performing
transformer. A toroidal transformer has the smallest size (by volume
and weight), inferior leakage inductance, and an electromagnetic
interference (EMI) that is much lower. The use of a toroidal
transformer is good for any transformer application that can
accommodate its shape. Although usable, a toroidal transformer are not
always practical for some applications.
