Abstract
The technology of this application relates to an arrangement for electric power conversion and dual electric drive, a system comprising the arrangement, a method of operating the arrangement, and a computer program for carrying out the method, which enable charging of dual-drive electric vehicles (EV) from a three-phase power grid without producing any torque, while making use of all the power electronics already existing for the traction system and the motor inductances. As such, space is saved and power density, efficiency and reliability are increased.
