Subsea power distribution system and method

A method of operating a subsea power distribution system, the method comprising:

• receiving input electrical power at a first voltage level on a power input;
• transforming received electrical power to a second voltage level which is relatively lower than the first voltage level via a distribution transformer;
• distributing received electrical power to two or more power distribution paths via a distribution circuit;
• rectifying transformed electrical power given out by the input transformer via a rectifier unit which gives out rectified electrical power;
• and
• for each of the two or more power distribution paths, performing the following:
• receiving electrical power at a separate breaker or switch,
• outputting the received electrical power to a cable,
• inverting the rectified electrical power given out by the rectifier unit to obtain AC electrical power at a third voltage level via an inverter,
• transforming the AC electrical power to a fourth voltage level which is relatively higher than the third voltage level via a distribution path transformer, and
• providing the transformed AC electrical power to a subsea load via a power output.
