Description

technical field [0001] The invention belongs to the field of power transformation of small transformers. Background technique [0002] A transformer is a static component that can convert one level of AC power into another level of AC power of the same frequency. Power transformers are one of the important equipment in power plants and substations. They are used for power transmission and distribution in power systems. Transformers play an important role in power operation. [0003] The voltage quality output by the transformer is an important symbol of power quality, which is closely related to the development of the national economy and the improvement of people's lives. The fluctuation range of the voltage directly affects the efficiency, performance and service life of electrical equipment. [0004] The fluctuation of the primary side grid voltage and the increase of the impedance voltage drop when the load increases will cause the instability of the output voltage of t...
