Abstract: In a power converter module, a first input area intended to be connected to a first predetermined electric potential (+V) or a second input area intended to be connected to a second predetermined electric potential (−V) can be connected to an output area. At least one group of switches is provided, each group of switches has two semiconductor switch units, and each of the semiconductor switch units has a gate terminal. An input terminal of one of the semiconductor switch units is connected to the first input area, and an input terminal of the other semiconductor switch unit is connected to the second input area. Each of the semiconductor switch units has an output terminal, which is connected to the output area. The two semiconductor switch units of the minimum of one group of switches are positioned facing each other in such a way that at least the output terminals are opposite each other.

Abstract: A drive system for a permanently excited electric motor having at least one phase winding including a half-bridge arrangement for each phase winding of the motor, an intermediate circuit connecting each half-bridge arrangement to a motor supply voltage source, and a drive arrangement for driving each half-bridge arrangement. In accordance with the driving via the drive arrangement, a voltage or a potential with a predetermined polarity is applied or can be applied for a predetermined duration by each half-bridge arrangement to that phase winding of the electric motor which is assigned to this half-bridge arrangement.

Abstract: A hybrid propulsion system for a motor vehicle, in which electric motors corresponding to the wheels of the motor vehicle are supplied by a generator, which generator is driven by an internal combustion engine, in particular via a direct current intermediate circuit. To be able to start the internal combustion engine, in the event of the failure of the battery provided for starting the internal combustion engine, by pushing or towing the vehicle or rolling it downhill, the electric motors can be switched over to operate as generators, and the generator can be switched over to operate as a motor, during an emergency starting phase, once the speed of travel of the vehicle exceeds a specified speed threshold. The emergency starting attempt can be initiated by the driver by means of a control mechanism, e.g. a manually actuated control switch or the accelerator pedal. If necessary, the speed threshold can be measured by means of a speed sensor.
