Abstract: A device (2) for the on-demand commutation of an electrical current from a first line branch (14, 3; 36) to another, second line branch (4; 41; 71) is created, which has a number of power semiconductor switching elements (7; 47; 53), which are arranged in series and/or parallel to one another in the second line branch (4; 41; 71), and a control unit (18; 51) for controlling the number of power semiconductor switching elements (7; 47; 53). The control unit (18; 51) is adapted to apply to each of the number of power semiconductor switching elements (7; 47; 53) an increased control voltage (VGE) whose level is above the maximum permissible control voltage specified for continuous operation, in order to switch on or maintain the conduction of the number of power semiconductor switching elements and to cause an increased current flow through it, whose current rating is at least double the nominal operating current. The control unit (18; 51) is further adapted to switch off the number of power semiconductor switching elements after a respectively provided short switch-on duration by switching off the control voltage (VGE) again while they conduct an increased current flow. The device (2) can thus be designed for a higher power in operation, or, at a given operating power, the semiconductor area and size of the device (2) can be reduced.

Abstract: A method of controlling a power system that includes an electrical machine, e.g., wind turbine generator, a power converter, a DC circuit and a dynamic braking system (DBS) having a braking circuit having a braking resistor and being connected in series to the DC circuit, is provided. The method includes operating the DBS and controlling operation of the electrical machine based on a prevailing temperature of the braking circuit, stopping the electrical machine and controlling the electrical machine to be restarted at its rated output power once the prevailing temperature of the braking resistor reaches or falls below a lower temperature threshold. The electrical machine may be restarted at a lower output power and after restarting, its output power can be increased based on a power starting profile as the braking resistor cools.

Abstract: A watertight enclosure for the underwater confinement of a device includes a set of ellipsoidal modules juxtaposed in a watertight manner and internally delimiting at least one volume receiving the device. It has been found that producing a watertight enclosure by means of juxtaposed ellipsoidal modules enables a total weight saving of the order of one third compared to a cylindrical envelope.

Abstract: A method of controlling an inverter, which is connected between a photovoltaic generator and a power supply network for ride-through of a network fault, is disclosed. A voltage dip is detected in the network voltage and the voltage (Udc) of a DC voltage link of the inverter is monitored. When it is detected that the DC link voltage (Udc) exceeds an upper limit value (UTHup), an operating mode for ride-through of the network fault (FRT) is started. The upper limit value (UTHup) corresponds to a saturation voltage Udc,nom(max) in the specific Iac/Udc characteristic curve of the inverter, above which the maximum AC output current Iac,max of the inverter decreases. In the FRT operating mode, an energy dissipation device is activated, which is adapted to dissipate power from the DC voltage link, if necessary, and is controlled to keep the DC link voltage (Udc) within a range (Udc−ΔU

Abstract: A power converter arrangement is described. The power converter includes a dc link and a power converter. The dc link is operably connected between a generator, or other power source, that provides an output voltage in use and a dc network. The power converter includes an inverter connected across the dc link in parallel with the generator, an isolation transformer having a primary tap changer and a secondary tap changer, and a rectifier. The rectifier has ac terminals connected to the secondary tap changer, a first dc terminal connected to the dc link, and a second dc terminal connected to the dc network. The dc terminal voltage of the rectifier is therefore summated with the output voltage of the generator to provide a converter output voltage.
