1. A wind turbine nacelle configured for mounting on a wind turbine tower and housing a rotor-supporting assembly supporting a rotor, the nacelle further housing a power conversion assembly, the nacelle comprising:
a main unit arranged to be connected to the wind turbine tower and housing the rotor-supporting assembly, and
at least one auxiliary unit housing an operative component forming part of the power conversion assembly,
wherein:
the main unit and the auxiliary unit are separate units configured to be connected by a unit fixation structure at an interface,
the operative component is suspended directly on the main unit, and
the main unit and the at least one auxiliary unit are arranged side by side in a direction transverse to a rotational axis defined by the rotor-supporting assembly.
