WebA variable transformer is a type of transformer that can provide a variable secondary voltage from the same primary voltage. It can vary the output voltage by changing the number of turns or using different tap points or by variable coupling. A Variac is the most common variable autotransformer. Single Phase Separate Winding Transformer WebNov 13, 2024 · I. Working Principle. The core of the toroidal transformer is made of high-quality cold-rolled silicon steel sheets (thickness is generally below 0.35mm), seamlessly rolled, which makes its core performance better than traditional laminated cores. The coil of the toroidal transformer is evenly wound on the iron core, and the direction of the …
