Interface functions, electrical components, electronic components or control units for the operation of the electric motor are located on the printed circuit boards.

An inverter device (1), comprising a first printed circuit board (2) on which a transformer (3) is arranged; a second printed circuit board (4) which is arranged parallel to the first printed circuit board (2) at a distance from the sides of the transformer (3); and a cover element (5) which is arranged between the printed circuit boards (2, 4) for the purpose of electromagnetic shielding and has a through opening (6) through which the transformer (3) passes;
wherein the cover element (5) comprises a shielding unit (7) which surrounds the through opening (6) peripherally at least in some places and extends in the direction of the second printed circuit board (4).

A method of producing a semiconductor module arrangement includes providing a first subassembly having a number N1 of first adjustment openings, a second subassembly having a number N2 of second adjustment openings and a third subassembly having a plurality of adjustment pins which are fixedly connected to one another, the first subassembly, the second subassembly and the third subassembly being independent of one another and not connected to one another. The first subassembly, the second subassembly and the third subassembly are arranged relative to one another in such a way that each of the adjustment pins engages into one of the first adjustment openings and/or into one of the second adjustment openings.

A seal cover for closing an annular opening portion having locking projections provided on an outer peripheral surface includes a fitting portion having a seal ring (example of a sealing member) fit on an outer peripheral surface and locking portions configured to be pushed and resiliently deformed by the locking projections and move over the locking projections to be locked to the locking projections when the fitting portion is fit into the opening portion. Tapered surfaces for delaying a time point when the locking portions are maximally resiliently deformed from a time point when the seal ring is maximally compressed when the fitting portion is fit and inserted into the opening portion are formed on front end parts of the locking portions in a connecting direction.

The integrated dual-motor controller includes a controller housing, a bus magnetic ring component, an all-in-one module, a control plate, an isolation plate and a drive plate. The bus magnetic ring component, the all-in-one module, the control plate, the isolation plate and the drive plate are all integrated in the controller housing. The integrated dual-motor controller is designed to achieve a high level of integration, and a modular design is used inside to facilitate mounting and reduce the size.

A mechanical enclosure for a power converter is disclosed. In some embodiments, the mechanical enclosure comprises a base; a first compartment configured for receiving one or more electronic devices; and a second compartment configured for receiving a magnetic device, the second compartment formed by a cavity protruding from a bottom surface of the base.

A battery charger for vehicles comprises one outer container, one electronic appliance housed inside the container, operatively connectable to an electric battery of a vehicle and configured for the recharge of the battery, and one cooling circuit of the electronic appliance, wherein the electronic appliance comprises one electronic board provided with an insulated metal substrate associated with the cooling circuit, with a layer of electrically insulating material made on one portion of the insulated metal substrate, and with one electronic circuit made on the layer of electrically insulating material, in which the electronic board comprises one conductive metal bar for the transport and the distribution of current, electrically connected to the electronic circuit and provided with one portion arranged in direct contact with one surface portion of the electronic board, for the cooling of the conductive metal bar by the cooling circuit.

The present disclosure includes drive modules for motor-drive assemblies of an industrial automation system. The drive modules may include a housing having a cavity and may also include power circuitry and control circuitry. The power circuitry may convert input DC power to three-phase controlled frequency AC power and may supply the three-phase controlled frequency AC power to a motor. The control circuitry may apply control signals to control operation of the motor. The drive module may also include an adapter that couples to a first end of the housing and couples the housing to the motor. The adapter may be removable and sized according to a frame size of the motor such that the drive module is compatible with the motor. The housing may be independent of the frame size of the motor. As such, the housing may be interchangeable for any motor frame size and/or motor power.

A power convertor has a casing and a power conversion circuit arranged in an internal chamber of the casing. The casing has a first wall member as a specific side wall. A plurality of connector opening parts are formed in the first wall member. At least two of the plurality of connector opening parts formed in the first wall member are arranged at different positions facing a different direction from each other.

In the case where as a communication means among two or more control circuit boards corresponding to an on-vehicle environment, a wire harness is mounted, space-saving efficiency and assembly efficiency pose problems. When a board-to-board connector is utilized, arrangement of the control circuit boards cannot freely be performed, due to restriction of predetermined specific dimensions. An electric-power conversion apparatus includes a cooling device having a first surface, a second surface opposite to the first surface, and a hole penetrating the first surface and the second surface, a first control circuit board provided at the first surface side, a second control circuit board provided at the second surface side, and a pin header having a mold portion that partially wraps a connection pin penetrating the hole so as to connect the first control circuit board with the second control circuit board and that is fixed to the cooling device.
