In a power converter module, a first input area intended to be connected to a first predetermined electric potential (&plus;V) or a second input area intended to be connected to a second predetermined electric potential (&minus;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.

Power converter module

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. An operating state registering arrangement registers an operating state of the drive system and/or of the electric motor, where the drive arrangement is designed such that, when the presence of at least one predetermined operating state in the drive system and/or in the electric motor is registered by the operating state registering arrangement, a command is generated to produce a short circuit between each terminal of the motor.
