Abstract

An arrangement (1) comprises: an electric machine (2, 2') with a first winding system (WS1) and a second winding system (WS2), wherein at least one electrical conductor (120) of the first winding system (WS1) and at least one electrical conductor (121) of the second winding system (WS2) are at least partially wound around a common winding axis (A), wherein turns of the electrical conductors (120, 121) alternate in a direction of the winding axis (A); a first inverter (134A) for supplying the first winding system (WS1) with a multi-phase current; a second inverter (134B) for supplying the second winding system (WS2) with a multi-phase current; and a DC bus (30) providing a DC current to each of the inverters (134A, 134B), wherein at least one of the inverters (134A, 134B) is electrically connected to the DC bus (30) and/or to the electrical conductors (120, 121) of the respective winding system (WS1, WS2) via protection switches (14).
