Abstract
The invention relates to an electric frequency changing device (2, 3) for changing the frequency of an electric power supply (6, 8). The electric frequency changing (2, 3) device comprises at least one fast-acting electric potential changing means (11) for changing the electric potential (U) of at least one part of the electric frequency changing device (2, 3) relative to ground potential.
