Drive transformer

The utility model relates to a drive transformer. The drive transformer comprises a shell and a magnetic core arranged in the shell, the magnetic core is made of ultracrystalline materials, two mutually parallel insulated plates are arranged on the two sides of the shell, U-shaped grooves are formed in the insulated plates and the side surface of the shell, the insulated plates are perpendicular to the bottom of the shell, two mutually parallel connection plates are arranged on the bottom of the shell, the two ends of each connection plate are connected with the corresponding insulated plate, each connection plate and the corresponding insulated plate connected with the connection plate are on the same plane, an input pin and an output pin are arranged on the two sides of each connection plate, and fixed columns are arranged on the two sides of each insulated plate and are fixed to the side surface of the shell. According to the drive transformer, the U-shaped grooves are used for insulated isolation, insulation compression strength of the transformer is improved, the ultracrystalline annular magnetic core with a high voltage-second product is adopted, and on the premise of identical performance, the size of the transformer is reduced, loss of the transformer is reduced, and stability and reliability of the transformer are improved.
