Toroidal transformers are a type of electrical transformer that is characterized by their unique toroidal or doughnut-shaped core. This distinct design offers several advantages over traditional rectangular core transformers, making them a popular choice in a variety of applications.
The toroidal core is typically made from high-permeability silicon steel laminations that are wound into a continuous ring shape. This construction minimizes air gaps and provides a more efficient magnetic path, resulting in lower magnetic leakage and higher efficiency. Compared to conventional transformers, toroidal transformers generally have a higher power-to-weight ratio, which means they can deliver the same power output while being significantly smaller and lighter. This makes them ideal for applications where space and weight are critical factors, such as in portable electronic devices, medical equipment, and aerospace systems.
