Introduction to Toroidal Transformers
Toroidal transformers are a type of electrical transformer with a doughnut – shaped core. They are known for their high efficiency, low electromagnetic interference (EMI), and compact size. The toroidal shape allows for a more uniform magnetic field distribution compared to other transformer designs, which results in less energy loss and better performance. These transformers are widely used in various applications, including audio equipment, power supplies, and industrial machinery. Toroidal Transformers
