  • Patent number: 9316238
    Abstract: There is provided an apparatus, method, computer program product, and a kit and method for upgrading, an apparatus for moving cargo. A bus for transmission of electrical energy, at least one load connected to the bus, said at least one load configured to transform electrical energy from the bus into movement of a cargo with respect to the apparatus energy transforming means configured to transform energy between electrical energy of the bus and potential energy of a hydraulic accumulator, wherein the apparatus is configured to store electrical energy from the bus as potential energy to the hydraulic accumulator and to supply the potential energy stored in the hydraulic accumulator as electrical energy to the at least one load.

  • Patent number: 8203291
    Abstract: A generator assembly including generator means and a first converter member (11), the generator means being arranged to convert mechanical power to electric power and comprising an AC generator (2), a voltage regulator (4) and an AC coupling, the voltage regulator (4) being arranged to regulate magnetization of the AC generator (2) on the basis of data associated with the voltage of the AC coupling of the generator means, the AC coupling being arranged to supply electric power from the AC generator (2) to the first converter member (11), and the first converter member (11) being arranged to rectify the voltage applied through the AC coupling into DC voltage. The first converter member (11) is arranged to adjust the power of the AC generator (2) by changing the component (I q) associated with the torque of the current passing through the AC coupling so as to provide the power of desired magnitude.
