ABSTRACT:
A toroidal electrical transformer having a low voltage coil, a high voltage coil and an annular magnetic core is disclosed. The preferred low voltage and high voltage coils are each continuous and form an arcuate elongated passage therethrough. The preferred annular magnetic core is wound in place in said arcuate elongated passage substantially from a continuous strip of magnetic material resulting in a toroidal transformer with continuous windings and a continuous wound core. Various components and sub-assemblies are also disclosed along with various apparatus and methods for producing such toroidal electrical transformers, its components and its sub-assemblies.
