A subsea electrical power transmission system may include a rectifier located at the source of the energy feeding a subsea DC power transmission path, e.g. a transmission cable with DC power. The voltage level can be adjusted to the actual installation and may typically be 100 kV. To reduce the voltage at the destination a step down chopper is used in one embodiment. This may reduce the voltage to a suitable input voltage for a VSD-inverters (VSD: variable speed drive) feeding electrical consumers such as motors.
