Method and apparatus for controlling parallel-connected power semiconductor switches
2014
The invention relates to a method (200) and a controller (1) for driving at least two parallel-connected power semiconductor switches (LHS1 LHSn ...) for switching a total current (i_ges). The at least two parallel-connected power semiconductor switch (LHS1 LHSn ...) each have a gate terminal for controlling the respective power semiconductor switch (LHS1 LHSn ...). It is an input terminal (EA) for supplying the total current (i_ges), an output terminal (AA) for deriving the GESAM current (i_ges) and a common Ansteueranschlusses (S) for receiving a common control signal (SI), comprising the states of opening or closing , provided. The at least two parallel-connected power semiconductor switch (LHS1 LHSn ...) on the input side to the input terminal (EA) and on the output side to the output terminal (AA) connected. There is provided at least one detection unit (EE) which is adapted to input the common drive signal (SI) to receive and at least two Einzelansteuersignale (SI1 ... SIn) in response to the common control signal (SI) for driving the at least two power semiconductor switches ( LHS1 LHSn ...) to be determined and the output side outputting the at least two determined Einzelansteuersignale to the respective gate terminals of the at least two power semiconductor switches. The at least two Einzelansteuersignale (SI1 ... SIN) are each in the open or close states and differ at least temporarily.
