摘要： The present invention provides a power converter that can be used to interface a generator (4) that provides variable voltage at variable frequency to a power grid or supply network (14). The generator (4) can be driven at variable speed by a source of driving torque that be a wind turbine or other renewable energy source. The power converter includes a machine rectifier (5) such as a diode bridge that is electrically connected to the stator of the generator (4) and rectifies the stator voltage to give a variable dc link voltage. The dc link voltage is filtered to provide a current source to a step-up inverter (7) (such as a pulse width modulated current source inverter) whose output is precisely regulated to provide the required supply network voltage and frequency.

摘要： The present invention provides an exciter assembly for supplying a field current to the rotor windings (16) of a superconducting synchronous machine. The exciter assembly includes a pulse transformer having a stationary primary winding (7) and a secondary winding (10) that is mounted to the rotor of the superconducting synchronous machine for rotation therewith. A switched mode power supply supplies a pulsed voltage to the primary winding (7) of the pulse transformer. The pulsed voltage developed at the secondary winding (10) of the pulse transformer is supplied to the rotor windings through a rectifier semiconductor device (11) and a pair of transfer leads (14). The rotor windings (16) and a flywheel semiconductor device (15) are located inside a cryogenic chamber or cryostat. The flywheel semiconductor device (15) is connected in parallel with the rotor windings (16) and operates in unison with the rectifier semiconductor device (11) in order to provide synchronous rectification of the switched mode power supply output. The switched mode power supply and both the primary and secondary windings (7, 10) of the pulse transformer are located outside the cryostat.

摘要： The electronic commutator circuits of the present invention provide forced commutation means that can be embedded within a known electronic commutator to overcome its low speed torque limitation. The forced commutation means consists of forced commutation enhancements to the basic switched stage using a pair of thyristors (1, 4). Capacitors (3, 6) may be pre-charged and synchronised to supplement coil voltages when discharged, thereby reducing commutation overlap duration and maximising the turn-off time available to allow the thyristors (1, 4) to attain forward blocking capability. Two means of providing such a capacitive discharge can be used. The first means initiates the capacitive discharge by the same thyristor that will carry the current following the commutation. The second means initiates the capacitive discharge by an auxiliary thyristor.

摘要： An improved rotary switch (e.g. a double pole double break switch) includes first and second poles (2, 4). Each pole including a rotatable bridging member (24) and a pair of fixed busbars (6a, 6b; 8a, 8b). Each busbar has at least one primary contact (14) and may also include a contact arm (12) with an arcing contact (28). The rotary switch is adapted such that the direction of current flow through the first pole (2) is opposite to the direction of current flow through the second pole (4). In this way, arcs established in the first pole (2) are deflected away from arcs established in the second pole (4).

摘要： The present invention relates to an ac generator (DOG1) comprising a plurality of galvanically-isolated multi-phase stator windings (sometimes called poly-phase stator windings). Each stator winding has a plurality of coils and is connected to an independent load such as the power distribution network (MVAC1, LVAC1) of a marine power distribution and propulsion system, for example. A number of galvanically-isolated power distribution islands having different frequencies and voltages may therefore be derived from a single generator.

摘要： In a marine power distribution and propulsion system with a medium voltage distribution busbar (MVAC1) and a low voltage distribution busbar (LVAC1) then a rectifier (SC) is controlled, optionally to provide active filtering and static compensation benefits. A common power supply system incorporating ac generators (G1 -G4) supplies power to the medium and low voltage distribution busbars. The rectifier (SC) is connected to the medium voltage distribution busbar (MVAC1). A controller (Co) uses feedback signals indicative of electrical quantities of the distribution voltages carried by both the medium voltage and low voltage distribution busbars (MVAC1, LVAC1) to control the rectifier (SC) to regulate electrical quantities at the ac terminals of the rectifier (SC) in order to achieve desired electrical quantities of the distribution voltage carried by the low voltage distribution busbar (LVAC1).
