A propulsion system comprising a generator set (1) and an electric propulsion motor (2) having high efficiency combined with a wide control range for the speed of the propulsion motor. The propulsion motor (2) is supplied with power via a controllable low-power electric converter (3) at low engine power and low speed, but is supplied with power via a circuit breaker (5) direct from the generator set (1) at high engine power and high speed. The system allows the generator set to be operated continually and is highly suitable as power supply for other electrical equipment (6, 7) as well. |
