摘要： A relay arrangement includes at least two series-connected relays, which are mechanically and electrically connected to a main printed circuit board via first terminals and second terminals, and at least one flat conductor for conducting current between the at least two series connected relays. The flat conductor is mechanically connected to the main printed circuit board and electrically and thermally connected to the first terminals of the relays, and the at least one flat conductor is configured to dissipate heat produced during operation of the relays.

摘要： An inverter for converting an input-end direct current into an output-end alternating current to be fed into an AC voltage supply system includes a first housing part with direct current connections for receiving direct current lines of a direct current generator, a second housing part with alternating current connections for receiving alternating current lines of an AC voltage supply system, a third housing part for accommodating power-electronics components of a DC voltage converter, and a fourth housing part for accommodating power-electronics components of an inverter bridge circuit. The housing parts each have an essentially planar rear wall and are arranged in such a way that they enclose a cooling-air duct with an essentially rectangular cross section, wherein the first housing part is arranged opposite the second housing part and the third housing part is arranged opposite the fourth housing part. The inverter also includes a heat sink, which has two essentially planar cooling faces opposite one another arranged in the cooling-air duct, wherein the cooling faces are assigned to the rear walls of the third housing part and the fourth housing part and are in thermal contact with power-electronics components arranged in these housing parts.

摘要： A method for limiting an output power of an inverter having an output bridge and an upstream boost converter includes determining a first measurement variable representative of a bridge temperature and a second measurement variable representative of an output power of the inverter. The method also includes determining a third measurement variable representative of a generator voltage at generator connections of the inverter or a fourth measurement variable representative of an output voltage at a power output of the inverter, and reducing the output power supplied to a power supply grid to a reduced power value. The reduced power value is determined based on the first measurement variable, the second measurement variable and at least one of the third and fourth measurement variables. A control device having such functionality is also disclosed.

摘要： A seal for an International Protection (IP)-sealing and electromagnetic capability (EMC)-shielding connection between a first housing component and a second housing component of an electrical or electronic device is disclosed. The seal includes an elastomer-containing sealing body and a metallic support that is embedded to some extent in the sealing body. The sealing body and the metallic support are connected to one another in an adhesive and/or form-fitting manner and thus form a material bond, and the metallic support has a plurality of contact segments, which project out of the sealing body and are configured such that the contact segments make electrical contact in resilient fashion with a first boundary surface that is assigned to the first housing component, and a second boundary surface that is assigned to the second housing component, the seal being pressed in between said boundary surfaces in an installed state.

摘要： Embodiments discussed herein include an inverter with a multi-part housing and internal cooling-air duct. In one example, the inverter can comprise a first housing part with direct current connections, a second housing part with alternating current connections, a third housing part for accommodating power-electronics components of a DC voltage converter, a fourth housing part for accommodating power-electronics components of an inverter bridge circuit, and a heat sink. The housing parts each have an essentially planar rear wall and are arranged in such a way that they enclose a cooling-air duct with an essentially rectangular cross section, wherein the first housing part is arranged opposite the second housing part and the third housing part is arranged opposite the fourth housing part. The heat sink has two essentially planar cooling faces opposite one another arranged in the cooling-air duct.
