Abstract:
In the case of an electronic circuit, comprising a drive unit, which generates at least one drive signal, two or more power semiconductor switches each having a first and a second main terminal, which power semiconductor switches can be switched synchronously by the drive signal, the first and the second main terminals of the power semiconductor switches in each case being electrically connected in parallel among one another, for each of the power semiconductor switches a first and a second electrically conductive connection for connection to the drive unit, a uniform dynamic current division between the power semiconductor switches is achieved according to the invention by virtue of the fact that a first inductance is provided in each of the first electrically conductive connections, and a second inductance is provided in each of the second electrically conductive connections, the first inductance being coupled to the second inductance for each of the power semiconductor switches.
