High-voltage Toroidal Transformer

High-voltage toroidal transformers are a type of toroidal transformer wound with silicon steel sheets. They are specialized transformers used primarily for high-voltage power conversion, transmission, and isolation. Typically featuring an input voltage of ≥1000V and power ratings ranging from 30W to 5000W or higher, these transformers are widely applied in power systems, electronic equipment, precision instruments, industrial controls, lighting systems, and other fields. They are particularly suited for scenarios with high requirements for power supply stability and anti-interference performance. Their core structure consists of a toroidal core, high-voltage windings, low-voltage windings, and insulating protective components. The core is wound using high-permeability silicon steel sheets or grain-oriented silicon steel strips, with windings evenly arranged around the core. Thanks to their unique toroidal structure, these transformers offer significant advantages over traditional EI-type transformers in terms of energy efficiency, size, and electromagnetic compatibility. Additionally, parameters such as voltage, power, and dimensions can be customized to meet the personalized power supply needs of different industries.

Due to its closed magnetic circuit path, the high-voltage toroidal transformer significantly reduces hysteresis loss and eddy current loss, achieving a conversion efficiency of over 95%. For the same power rating, it is smaller in size compared to traditional EI-type transformers. It features high withstand voltage levels, strong insulation performance, a compact structure, and good protective properties. In specific application scenarios, epoxy resin potting can be used to enhance the product's insulation and high-voltage output capability.
