Three-phase high-frequency transformer

The invention relates to a three-phase high-frequency transformer and aims to provide the three-phase high-frequency transformer to realize three-phase magnetic reluctance balance. Ferrite can be usedas magnetic cores of iron core columns, and structural simplicity is realized. The three-phase high-frequency transformer comprises an upper main iron yoke, a lower main iron yoke and three iron corecolumns, and each iron core column is provided with a primary coil and a secondary coil by winding. Two ends of the upper main iron yoke are connected to the two iron core columns on two sides, two ends of the lower main iron yoke are connected to the two iron core columns on two sides, and upper and lower ends of the middle iron core column are connected with the middle of the upper main iron yoke and the middle of the lower main iron yoke respectively. An upper auxiliary iron yoke is arranged above the upper main iron yoke, two ends of the upper auxiliary iron yoke are connected to the twoiron core columns on two si
