Product Introduction
A DC isolation transformer is a novel power isolation component that achieves power transfer and electrical isolation through different topological structures based on a high-frequency transformer. Its operating principle is as follows: the input DC voltage is first inverted into high-frequency AC, which then passes through the high-frequency transformer to accomplish electrical isolation and voltage conversion. The output is then rectified and filtered back into DC voltage, achieving complete electrical isolation between the input and output sides. Common model shapes include EE and EC types.
Product Features
DC isolation transformer is a high-frequency transformer that transfers energy through electromagnetic induction and provides electrical isolation between input and output voltages. It generally adopts a 1:1 turns ratio design, and its main function is isolation rather than voltage conversion.
Application Fields
DC isolation transformers are mainly used in:
FAQ
Q: What is the difference between a DC isolation transformer and a conventional DC transformer?
A: The difference lies in DC isolation. A conventional DC transformer only performs DC voltage conversion, with a possible electrical connection between the primary and secondary sides. It offers no isolation protection and is unable to block DC interference or leakage current.
In contrast, a DC isolation transformer features complete electrical isolation between the primary and secondary windings. It can isolate DC leakage, surges, and spurious interference, providing enhanced safety protection and noise immunity. It is suitable for applications with high requirements for DC power safety and equipment precision.
