A power generator system that is suitable for use on medium-sized and large watercraft. The system includes a generator that is driven by a hydraulic motor that is coupled to the main engine through a variable hydraulic pump. In order to maintain a stable, substantially constant-frequency power output from the generator as the main engine operates over a wide range of operating speeds, a controller receives a power frequency input signal and a hydraulic pump speed input signal, and uses both of these input signals to generate an output control signal to ...


The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. An electric power generator system operably connected to a watercraft main engine, the generator system comprising: a variable hydraulic pump drivably connected to the watercraft main engine, the variable hydraulic pump including a regulator for adjusting a flow rate from the variable hydraulic pump; a hydraulic motor fluidly connected to the variable hydraulic pump such that the fluid flow from the variable hydraulic pump drives the hydrau...
