Abstract: The present invention provides an improved single-layer coil for a rotating or linear electrical machine. The coil has a first endwinding that is substantially straight to a longitudinal axis of the coil and a second endwinding that is bent relative to the longitudinal axis of the coil. The coil therefore has differently shaped endwindings with one end 12 being ‘straight’ and the other end being ‘bent.’

Abstract: An electrical system forming part of a solar power plant is described. The electrical system includes a plurality of photovoltaic (PV) panels, a power converter, and a controller. In response to a detected electric arc on the DC side of the power converter, the controller is configured to enable a short circuit state of the power converter by controlling semiconductor switches of the power converter (e.g., turning on some or all of the semiconductor switches) to create a short circuit between DC input terminals of the power converter. The short circuit path though the power converter will extinguish the detected electric arc in the connected DC circuit.

Abstract: A method of short-circuiting a faulty submodule for a voltage-source power converter is disclosed. The submodule is based on a full-bridge, asymmetric full-bridge or half-bridge circuit design having power semiconductor switches with anti-parallel freewheeling diodes and optionally non-controllable semiconductor valves. The method 36 includes identifying a faulty semiconductor device and determining a failure mode selected from a short-circuit failure mode and an open circuit failure mode. The method further includes selecting a minimum number of power semiconductor switches suitable to provide a bypass path through the submodule depending on the identified faulty semiconductor device and the determined failure mode and driving the selected power semiconductor switches by a modified driving voltage compared to normal operation to cause them to break down in order to provide a durable, stable, low impedance short-circuit path between the AC voltage terminals of the submodule. A power converter comprising a series connection of such submodules and supporting the method of short-circuiting a faulty submodule is also disclosed.

Abstract: A dual submodule is created for a modular multilevel converter, whereby the dual submodule has two interconnected submodules, whereby each submodule has an asymmetrical half-bridge circuit with two parallel bridge branches, which are connected between a first and a second terminal connection of the submodule, whereby each bridge branch is formed from a series circuit of a power semiconductor switch, and a diode, whereby the power semiconductor switch is allocated to an antiparallel free-wheeling diode, and has a capacitor, which is connected in parallel with the asymmetrical half-bridge circuit between the first and the second terminal connections of the module. The submodules are connected to each other via their AC terminals to form the dual submodule. Further, a modular multilevel converter is created, comprising a number of such dual submodules in each of its converter branches.

Abstract: A method, apparatus, and system to control and test a solar inverter are provided. The method commissions a solar inverter of a solar plant before it is placed into power production. The commissioning process verifies that the inverter to be tested is functioning as intended by connecting a first inverter to the inverter to be commissioned, and using the first inverter to emulate the power grid without being connected to the power grid, and circulate reactive and limited active power between the first inverter and the inverter to be commissioned.

Abstract: A stator for an electrical machine (e.g., a motor or generator) is described. The stator includes a stator core consisting of a plurality of axially adjacent generally annular laminations. The stator has axially extending stator teeth between adjacent pairs of which are formed axially extending stator slots for receiving conductors of a stator winding. At least one of the stator teeth includes an axially extending cooling passageway through which a cooling fluid flows in use. The electrical machine can include means for circulating cooling fluid through the cooling passageway(s) to cool the stacked laminations and means for circulating air around the stator along an air cooling circuit where the circulated air is cooled by the stator laminations and there is no need for a separate heat exchanger.

Abstract: A switch module and a converter developed with the help of a switch module. The switch module presents two series connections comprising a power semi-conductor switch and a diode and. Parallel to the first series connection a first capacitor is connected. Between the first capacitor and the second series connection at least one intermediate connection is connected. This is designed as quadripole, whereby between both the output connections a second capacitor is connected. The first output connection is connected through a third power semi-conductor switch with the first input connection. The second output connection is connected with the cathode of a third diode, whose anode is connected with the second input connection of the intermediate circuit. With this switch module at least five voltage levels can be set up for an output voltage. For each additionally present intermediate circuit the number of the possible voltage levels increases by two.
