Abstract :
Variable voltage, variable frequency (VVVF) systems have been proposed for use in marine propulsion systems. This paper investigates the use of these systems in cases where there is a significant ship service load, including pulse power loads. The paper provides a steady state analysis of the VVVF system showing overall fuel savings as compared to the conventional electric drive systems. The paper also presents simulations suggesting that the VVVF system has the capability to serve significant levels of pulse loads.
