A power converter, includes: a first terminal, a second terminal, a third terminal and a fourth terminal; stored-energy-source terminals, to which a stored energy source can be connected; four inverter bridge branches, which are formed from semiconductor switching devices, the inverter bridge branches each having a center tap, each center tap being assigned to one of the terminals, and the inverter bridge branches being interconnected and controllable such that electrical energy can be transferred bidirectionally between the stored-energy-source terminals and the first terminal, the second terminal, the third terminal and/or the fourth terminal; and a control unit, which is designed to control the semiconductor switching devices of the inverter bridge branches.

Power converter, charging post and vehicle

An electrical plug forms an electrical plug connection to a coupling that is complementary to the plug. The electrical plug includes a plurality of metal contact elements for electrically contacting an electrical apparatus arranged in a housing, a contact carrier element and a receiving element for receiving the coupling in a receiving space surrounded by the receiving element. The receiving element can be introduced into the housing in a first direction through an opening in the housing. The receiving element, to form the plug, can be brought into engagement in the first direction with the contact carrier element, the contact elements being guided through the contact carrier element and having contact regions which, when the receiving element has been brought into engagement with the contact carrier element, extend into the receiving space, away from the contact carrier element, counter to the first direction.

Electrical plug, electrical device, electrical plug connection, and method for producing an electrical device

A system includes a first, particularly mobile, unit which has a number m of function terminals, a first potential equalization terminal, which is intended to be galvanically connected to a reference potential, an energy source, a power converter, which is fed from the energy source and produces a number m of signals, a switching unit, the signals produced by the power converter being fed to the input side of the switching unit, and the output side of the switching unit being connected to the function terminals, or the input side of the switching unit being connected to the energy source and the output side of the switching unit being connected to the power converter, an insulation monitoring unit, which detects an undesired galvanic connection of a component of the system to the reference potential, and a connection monitoring unit, which monitors whether the first potential equalization terminal is properly electrically connected to a corresponding potential equalization terminal of a second unit to be connected to the first unit.

System for distributing electrical energy

A coil component includes a cup, a magnetic core, an electric conductor wound around the core, a cover, which closes the cup, and electric terminal contacts, which are in electric contact with ends of the electric conductor. The core and the electric conductor are arranged in the cup and the cup is filled with potting compound.

Coil component

A charging system has: a number of connections for connecting at least one electric energy store to be charged; a number n of at least three inverter bridges, each of which has a center tap; a number n of electric filters, wherein the input of each filter of the number n of filters is electrically connected to a respective corresponding center tap of an inverter bridge of the number of inverter bridges; a controllable assigning unit which is inserted between a respective output of a filter of the number n of filters and the number of connections and which is designed to electrically assign the output of each filter of the number n of filters to a respective corresponding connection of the number of connections depending on at least one actuation signal; and a control unit which is designed to generate the at least one actuation signal depending on a desired charge mode of the charging system.

Charging system

An electrical controller includes a housing, wherein the housing has cooling air openings on two different housing sides. A heat sink is arranged inside the housing, in particular so as to be protected against contact, and forms a cooling air channel, wherein the cooling air channel runs between the cooling air openings of the different housing sides. An electrically insulating holding element is designed to mechanically fix the heat sink inside the housing in a manner electrically insulated from the housing. A number of components to be cooled are provided, wherein the components are thermally conductively coupled to the heat sink and are held by the heat sink.

A control device for an electrical device such as an electric motor is provided. The control device is designed to, when necessary, bring about a safe, torque-free state of an electric motor, in particular a field-weakened electric motor. The control device includes a safety unit which is designed to generate safety control signals. A driver unit of the control device is designed to generate, irrespective of a state of motor control signals, in the case of a first state pattern of the safety control signals, power semiconductor control signals in such a way that power semiconductors have a non-conductive state, in the case of a second state pattern of the safety control signals to generate the power semiconductor control signals in such a way that a bridge output terminal is electrically connected to a positive intermediate circuit potential, and in the case of a third state pattern of the safety control signals to generate the power semiconductor control signals in such a way that the bridge output terminal is electrically connected to a negative intermediate circuit potential.
