Abstract: A method for operating an electrical circuit including at least one half-bridge formed from two transistors wherein the electrical circuit is switched over between a first switching state, in which the first transistor of the half-bridge is switched to conductive by a first voltage value of a first control voltage and the second transistor of the half-bridge is switched to blocking by a second voltage value of a second control voltage, and a second switching state, in which the first transistor is switched to blocking by a second voltage value of the first control voltage and the second transistor is switched to conductive by a first voltage value of the second control voltage, wherein a dead time state, in which both transistors are switched to blocking, is assumed chronologically between the first switching state and the second switching state.

Abstract: A circuit arrangement for an electronic device having at least two semiconductor elements of the same type connected in parallel with each other. At least one first semiconductor element has a first characteristic and at least one second semiconductor element has a second characteristic. Each of the two characteristics is defined by at least one power loss. The at least one power loss of the at least one first semiconductor element has a first value, and the at least one power loss of the at least one second semiconductor element has a second value. The two values of the at least one power loss are different.

Abstract: A motor vehicle can be powered by a combustion engine or an electric machine or both. Coolant is conveyed in the coolant circuit first to the electric machine before being conveyed from the electric machine to the combustion engine for cooling both the combustion engine and the electric machine. A cooling device adjusts a temperature of the coolant in the coolant circuit in such a way that the cooling device adjusts the coolant to a first temperature, when the motor vehicle is powered by the combustion engine, and to a second temperature which is less than the first temperature, when the motor vehicle is powered by the electric machine and the combustion engine.

Abstract: A motor vehicle includes a hybrid drive having an internal combustion engine and an electric drive motor, and an air conditioning system having a compressor configured to compress a refrigerant, and an electric motor configured to operate the compressor and to start the internal combustion engine as electric starter when being coupled with the internal combustion engine. The electric motor has an inverter to operate the electric motor directly with high voltage of a high-voltage onboard electrical system of the motor vehicle so as to enable the electric motor to apply a mechanical torque for re-staring the internal combustion engine in case of need in the absence of any assistance from the electric drive motor. A clutch device mechanically couples the electric motor of the air conditioning system with the internal combustion engine in response to a control signal.
