‌ micro transformer ‌ is A kind of small transformer, usually refers to single-phase 20 kV·A and three-phase 50 kV·A transformer. It is characterized by small size, low cost, less wire, suitable for factory electrical control systems and other occasions requiring small transformers ‌.

Structure of micro transformer

The micro transformer is mainly composed of iron core and winding. The common shapes of the core are E, Sun, F and C shapes, usually made of silicon steel sheets stacked to reduce losses. The winding is called coil, most of the micro transformers use mutual inductance double coil structure, divided into primary side winding and secondary side winding ‌.

Application field of micro transformer

Micro-transformers are widely used in various electronic and electrical equipment, such as factory electrical control systems, medical equipment, mining systems, communication systems and so on. Due to its small size and low cost, micro transformers are especially suitable for occasions where space is limited and the demand for power is not large ‌.

Technical parameters and performance characteristics of micro transformer

The technical parameters of micro transformer include voltage conversion range, current carrying capacity and so on. Due to its small size, the load rate and utilization rate of micro-transformers are generally low, and capacitive compensation is usually not carried out. In addition, micro-transformers need to consider issues such as electromagnetic interference and thermal management when they are designed and manufactured to ensure their stable operation ‌.
