| 摘要 |
The present invention relates to power modules for controlling an input current to provide an output current, in particular, to such a power module (100) comprising at least one semiconductor switch for controlling the input current and a circuit substrate. The circuit substrate (108, 110) has at least one input terminal for being connected to an input voltage and at least one output terminal for outputting the output voltage. The input terminal and the output terminal are connected to each other via a main current path (104) that is controlled by the semiconductor switch. Said power module further comprises at least one transient current path (102) with extremely low inductivity for carrying a transient current during a switching operation of the semiconductor switch. The main path for the continuous current has a low ohmic resistance, but does not have to be designed to have a specifically low inductance.
