Abstract: An inductive device comprises a toroidal core and at least one electric conductor wound around the toroidal core and constituting at least one winding. The inductive device comprises a cooling element constituting a cylindrical cavity that contains the toroidal core and the electric conductor so that the axial direction of the toroidal core is parallel with the axial direction of the cylindrical cavity. The shape of the cylindrical cavity and the cross-section of the electric conductor are adapted to match each other to improve heat transfer from the electric conductor to the wall of the cylindrical cavity so that a wall of the cylindrical cavity is provided with axially directed grooves occupied by portions of the electric conductor on an outer perimeter of the winding.

Abstract: A positioning device (101) for producing a position signal indicative of a rotational position of a resolver is presented. The positioning device comprises a signal interface (102) for receiving alternating signals (V_cos, V_sin) from the resolver and a processing system (103) for generating the position signal based on position-dependent amplitudes of the alternating signals and on polarity information indicative of a polarity of an excitation signal (V_exc) of the resolver. The processing system is configured to recognize a polarity indicator, such as a change of frequency or phase, on a waveform of one or both of the alternating signals and to determine the polarity information based on the recognized polarity indicator. Thus, the polarity information related to the excitation signal is included in the alternating signals and therefore there is no need for a separate signaling channel for transferring the polarity information to the positioning device.

Abstract: A vessel includes electric connectors for receiving one or more direct voltages from a shore-side electric power system. The vessel includes a transmitter for transmitting, to the shore-side electric power system, a control signal enabling the shore-side electric power system to control the one or more direct voltages to be suitable for the vessel. Alternatively, the vessel includes one or more controllable direct voltage converters and a control system for controlling the one or more controllable direct voltage converters to convert the one or more direct voltages into one or more direct voltages suitable for the vessel. The vessel can be for example a ship, a boat, or a ferry.

Abstract: An electric power system includes electric energy sources and control equipment for controlling the electric energy sources in accordance with a target value of electric power produced by the electric power system. The control equipment activates and deactivates the electric energy sources based on a control value and on activation and deactivation limits. The control value can be the target value or the actual value of the electric power. The control equipment controls active electric energy sources according to the target value and according to power sharing defined for the active electric energy sources. The activation and deactivation limits as well as activation and deactivation order of the electric energy sources can be determined based on properties of the electric energy sources and on a prevailing operational situation of the electric power system.

Abstract: An electric power system comprises recording devices (101-105) located at different elements of the electric power system and configured to record waveform samples of quantities related to operation of the elements of the electric power system. The electric power system comprises a central device (106) configured to receive the recorded waveform samples from the recording devices. The recording devices are synchronized to maintain a common clock time and to associate, to each of the recorded waveform samples, one or more timing values indicative of the clock time during recording the waveform sample. As the timing values are associated to the waveform samples, it is possible to reconstruct a time order of phenomena indicated by the recorded waveform samples. Thus, it is possible to identify which of the phenomena are causes and which are consequences when analyzing for example what happened prior to a fault situation.

Abstract: A linear electric machine comprises a primary part (101) and a secondary part (102) linearly movable with respect to each other. The primary part comprises primary sections (103, 104) each having an airgap surface. The secondary part comprises secondary sections (105, 106) each having an airgap surface facing towards the air-gap surface of the respective primary section. Each primary section comprises force-generating windings (U1, V1, W1, U2, V2, W2) for generating a magnetic thrust force and a transversal magnetic force pulling the primary section towards the respective secondary section. The resultant of the transversal magnetic forces is controllable to levitate the primary part. The primary part further comprises one or more tilt-control windings (T1, T2) for controlling tilting of the primary part with respect to the secondary part.

Abstract: A device-system comprises parallel operating devices (105-107) for driving an operating quantity towards a target value, and a control system for controlling each device at least partly based on a device-specific integral term relating to a time integral of a device-specific error signal that is indicative of a deviation of the operating quantity from the target value. The control system comprises a stabilizing system that computes an arithmetic average of the device-specific integral terms and corrects the device-specific integral terms towards the computed arithmetic average. The correction of the device-specific integral terms makes it possible to avoid unwanted drifts in the device-specific integral terms in a situation where there are differences between the device-specific error signals. The devices can be peers to each other and thus redundancy is achieved because one device can be removed from or added to the device-system without actions from the other devices.

Abstract: An electric system of an electromechanical power transmission chain is provided that includes a first capacitive circuit, converter equipment between the first capacitive circuit and an electric machine, a second capacitive circuit, and a direct voltage converter between the first and second capacitive circuits. The electromechanical power transmission chain is a parallel transmission chain where the electric machine is mechanically connected to a combustion engine and to one or more actuators. The electric system includes a control system for controlling the direct voltage converter in response to changes in a first direct voltage of the first capacitive circuit and for controlling the converter equipment in response to changes in a second direct voltage of the second capacitive circuit. The first direct voltage is kept on a predetermined voltage range whereas the second direct voltage is allowed to fluctuate in order to respond to peak power needs.
