Abstract: A device and a method for determining a load index of a power converter as part of a charging device for electrically operated vehicles. Included is a power converter which has power electronics switching equipment and a control device for controlling this, wherein a logging device stores a plurality, preferably at least three, particularly at least five, of characteristics of the charging device and in particular of the power converter, having an evaluation device, which evaluates the plurality of characteristics and determines the load index therefrom and, when a first threshold value of the load index is reached, transmits this information about this to a first superordinate decision device.

Abstract: A method is described forming a first sub-leadframe having one or more first connection terminals; forming a second sub-leadframe having one or more second connection terminals; joining the first and second sub-leadframes to form a leadframe such that at least some of the first connection terminals overlap at least some of the second connection terminals.

Abstract: A power electronic module (2) includes at least one semiconductor switch (4) and a gate-source control unit. The gate-source control unit includes an asymmetric transient voltage suppressor (TVS) diode (8) or two Zener diodes (10, 10?) or one or more avalanche diodes arranged between the gate terminal (G) and the source terminal (S) of the semiconductor switch (4).
