Abstract: An electrical switch. The electrical switch includes at least one fixed contact and a movable contact contacting the fixed contact. At least one shutter element is arranged to move in synchronism with the movable contact. The shutter element is positioned in an extended position between the fixed contact and the movable contact and in a contracted position outside the patch of the movable contact allowing the movable contact to turn from the open position to the closed position.

Abstract: Monitoring aging in an electric drive system includes energizing the electric drive system such that electrical current flows through a power semiconductor device therein, determining a value indicative of a voltage across the power semiconductor device, at a current level where voltage is substantially independent of temperature, comparing the determined value with a reference value, and outputting a signal responsive to a difference between the values that is indicative of an aging state of the power semiconductor device.

Abstract: A method and apparatus are provided for balancing currents of two or more parallel-connected power semiconductor switches during an on-state of the switches. A control terminal of each switch is driven by a driver unit. The method includes determining ratios between the currents through the switches. For each switch, the method includes controlling the voltage at the control terminal on the basis of the ratios by controlling a level of a supply voltage of the driver unit of the switch, and after a turn-on commutation transient, modulating the output of the driver unit. The duty cycle of the modulation is controlled to minimize the time required for the transition of the voltage at the control terminal from the one voltage level to another.

Abstract: A ship comprising a hull having a transom and a bottom, and an azimuthing propulsion unit arranged to the bottom of the ship hull, which azimuthing propulsion unit comprises a propeller. The azimuthing propulsion unit comprises an exposed operation mode in which the propeller sets, behind the transom of the hull and that the azimuthing propulsion unit is rotatable and comprises a protected position mode in which the azimuthing propulsion unit stays below the hull of the ship.

Abstract: A vessel and a method in a vessel with a hull and a propulsion unit. The propulsion unit comprises a hollow strut rotatably attached to the hull of the vessel, a propeller shaft having an axial centre line and being positioned and supported in the lower portion of the strut with bearings, a propeller being attached to at least one end of the propeller shaft protruding from the lower portion of the strut, and an electric motor driving the propeller shaft. An additional support arrangement is positioned at least in one end portion of the propeller shaft axially outwards from the bearings. The support arrangement comprises a first support surface formed in connection with the propeller shaft and a second support surface mating with the first support surface and being formed in connection with the lower portion of the strut. The second support surface is positioned at a predetermined distance from the first support surface so that a slot is formed between the first support surface and the second support surface facing towards each other. The being of the propeller shaft due to external loads acting on the propeller is restricted to a predetermined maximum value with the support surfaces.
