Abstract:
1. A propulsion system, comprising: (a) a plurality of prime power systems, each prime power system comprising; (b) a direct current bus connecting the plurality of prime power systems, the direct current bus being operable to carry the direct current electrical energy to and/or from the prime power systems; (c) a voltage sensor for measuring a voltage level across the direct current bus; (d) a plurality of current sensors, each current sensor measuring a direct current electrical energy outputted by a selected prime power system; and (e) a control system operable, based on the measured voltage level across the direct current bus and the respective measured direct current electrical energy into and/or out of each prime power system, to control at least one of:
