In October 2022, the design office of KSC Drive Systems LLC in cooperation with Transconverter LLC set about developing a module BLG20.

The module BLG20 under development is meant to charge a storage battery and power the circuits of rolling stock with a voltage 110 V DC. It should have the input voltage 670 V DC, the controlled output current from 0 to 200 A and the nominal output power 20 kW.

The development goal is an import substitution of the similar modules produced by Siemens AG (Germany) which are used in auxiliary converters of the electric trains “Lastochka” (ES1, ES1P, ES2G, ES2GP) and passenger cars of the RIC.

It is planned to release a mock-up sample of the module BLG20 in August 2023.
