In February 2018 the design office of Transconverter LLC completed the development of the TGF56 U2 auxiliary converter for AC locomotives.

The TGF56 U2 auxiliary converter is designed for converting single-phase alternating voltage of winding of an electric locomotive traction transformer into three-phase voltages for supplying asynchronous electric motors of auxiliary machines and other devices of an AC locomotive.

The TGF56 U2 converter has two independent output channels with a three-phase rated voltage of 440 V, 60 Hz.

Each output channel is rated for 90 kVA power.

Completion of the first sample of the TGF56 U2 auxiliary converter is planned for May 2018.
