  "textContent": "A hot standby power supply for a variable frequency drive of a floating vessel is provided. The variable frequency drive can power an electric motor of the floating vessel. The hot standby power supply has a power input for receiving electric power from a main power supply of the floating vessel. It further has a first electric connection configured to supply electric power at a first voltage level to a converter power input of the variable frequency drive and a second electric connection configured to supply electric power at a second voltage level to control power input of the variable frequency drive. The first voltage level is higher than the second voltage level. A transformer is further provided for transforming received electric power to the first voltage level or to the second voltage level.",
