A power distribution system is described. The system includes first and second ac busbars (2a, 2b) connected to ac generators (G1, G2). A first active rectifier/inverter (12a) has ac input terminals electrically connected to the first ac busbar (2a). A second active rectifier/inverter (12b) has ac input terminals electrically connected to the second ac busbar (2b). A first dc interface (22a) is electrically connected to dc output terminals of the first active rectifier/inverter (12a) and a second dc interface (22b) is electrically connected to dc output terminals of the second active rectifier/inverter (12b). The first and second dc interfaces (22a, 22b) include reverse blocking means, e.g., diodes (30a, 30b) or other suitable power semiconductor devices that provide a reverse blocking action. A third active rectifier/inverter (38) operates as a drive and has dc input terminals electrically connected in the parallel to dc output terminals of the first and second dc interfaces (22a, 22b) by means of an interposing dc busbar (34). An electric motor, that can optionally form part of a marine thruster T1, is electrically connected to ac output terminals of the third active rectifier/inverter (38).
