Description

Technical Field

[0001] The invention relates to the field of rectifier transformers, and in particular to an improved rectifier transformer. Background Art

[0002] A rectifier transformer is a power transformer specially designed for use in rectifier circuits. Its main function is to convert alternating current (AC) into direct current (DC). By changing the ratio of the number of turns of the coil, the rectifier transformer can adjust the output of voltage and current. It is usually used in high-voltage or high-power DC power supply applications, such as electrolysis, DC motor drive, and industrial power supply systems. The design of the rectifier transformer usually includes multiple windings to provide suitable output under different voltage requirements. In addition, it is also used in conjunction with a rectifier. The rectifier converts the AC power that has been stepped down by the transformer into DC power to meet the needs of the equipment or system. The rectifier transformer plays a key role in power electronics and industrial control to ensure the stability and reliability of power supply.
