Abstract
A subsea power distribution system is provided. The subsea power distribution system includes a power input for receiving electrical power at a first voltage level and an input transformer coupled to the power input and adapted to transform received electrical power to a second voltage level which is lower than the first voltage level. A distribution circuit distributes received electrical power to two or more power distribution paths. At least one rectifier unit is-receives transformed electrical power from the input transformer and outputs rectified electrical power. The two or more power distribution paths each have an inverter configured to receive rectified electrical power from the rectifier unit and to output AC electrical power at a third voltage level, and a distribution path transformer coupled to the respective inverter and configured to transform the output AC electric power to a fourth voltage level which is higher than the third voltage level.
