The disclosure relates to a power module including a semiconductor power circuit, a conductor and a first core part being arranged besides the conductor such that it can form a core together with a second core part. The disclosure further relates to methods for manufacturing such a power module.

An electromagnetic shield including a base portion and opposing recess walls extending from the base portion at an angle with respect to a plane in which the base portion extends, so as to, together with the base portion, define a recess. At least one recess wall may be arranged such that it has a distal edge with respect to the base portion, wherein the distal edge includes a cylindrical portion. In alternative or in addition, at least one recess wall may be arranged such that at least a portion thereof curves outwards or inwards with respect to the recess.

The invention relates to an assembly of modules for an electrical circuit comprising: a module support for at least two modules and at least two modules, each module comprising two complementary connectable sub-modules. The module support comprises for each sub-module at least an alignment member adapted to individually align the sub-module during its installation on the module support in such way to connect it to complementary sub-module already installed on the module support to form one of the modules. The invention also relates on a module support, a module and a Flexible Alternative Current Transmission Systems.

A power converter comprises a stack of circuit layers, a magnetic core, an area of the stack of circuit layers, and power converter circuit components mounted on the stack of circuit layers. The stack of circuit layers has a hole which extends through each of the circuit layers. A portion of the circuit layers form an energy transfer element that comprises an input winding and an output winding. Each winding includes at least one winding layer having a planar winding and connections for electrical connectivity. The magnetic core is positioned within the hole substantially perpendicular to the stack. The area of the stack of circuit layers encompasses the windings and connections for electrical connectivity of the input and output windings. The power converter circuit components are mounted within the area of the stack and external to the magnetic core.

A capacitor assembly includes a traction inverter system housing and a set of power electronics defining two or more contacts, the set of power electronics mounted within the traction inverter system housing. A capacitor housing containing a capacitor is mounted within the traction inverter system housing. The capacitor includes two or more terminals extending outwardly therefrom and overlapping the two or more contacts. A terminal block is secured to the capacitor housing independent of attachment of the two or more contacts to the two or more terminals. The terminal block is configured to support the two or more terminals during a fastening operation attaching the two or more terminals to the two or more contacts. The terminal block may also be secured to the capacitor housing.

A power converter includes a semiconductor module, a capacitor module, a control board, and an insulating plate. The capacitor module includes a smoothing capacitor, a first connection terminal electrically connected to the smoothing capacitor and a power supply outside the power converter, and a second connection terminal electrically connected to the semiconductor module. The insulating plate is located between the capacitor module and the control board so as to cover at least one of the first connection terminal and the second connection terminal.

There is disclosed herein a converter valve assembly (20) for a power grid system, comprising two or more equal groups (6a, 6b, 6c) of prismatic converter cells (3a-ad), each group (6a, 6b, 6c) being arranged in a respective plane (7a, 7b, 7c) of a plurality of parallel planes spaced apart along a horizontal axis (8). Converter cells (3a-j) in a group (6a) are connected in series, and the groups (6a, 6b, 6c) are connected in series along the axis (8). The prismatic converter cells (3a-j) in a group (6a) are arranged such that there is a corresponding voltage difference between each converter cell (3a-j) in the group (6a) and each corresponding converter cell (3k-t) in an adjacent group (6b) that is a spatially nearest to said each converter cell (3a-j), during operation of the converter valve assembly (20). Therefore, a spacing between groups may be reduced and an overall volume of the converter valve assembly may be reduced.
