    摘要: A method for the dynamic load-balancing of series- and/or parallel-wired power semiconductor circuits (S1...S4) is disclosed. Individual switching signals (iG1, iG2) for the power semiconductor circuits (S1...S4) are generated, whereby a synchronous sampling timepoint (tsj) with system-wide validity is determined independently for each power semiconductor circuit (S1...S4) based on a synchronous event (es) in the whole circuit (1, 4). Error signals between actual values (ai), simultaneously measured at the sampling timepoint (tsj) and given set values (as) of an asynchronous state variable (a(t)) for the power semiconductor circuit (S1...S4), are reduced in the same or subsequent switching cycle. Alternatively, error signals between actual time values (tai) and set time values (tas) are minimised, whereby the set time values (tai) are measured on a global given threshold value ( epsilon a), for an asynchronous state variable (a(t)) for the power semiconductor circuit (S1...S4), being exceeded. Execution examples include: shifting the sampling timepoint (tsj) by a global set time interval ( DELTA t0), set value determination locally or globally, for example by means of averaging actual values (ai, tai), additional balancing of the gradients of asynchronous state variables (a(t)). Absence of a central sampling command, improves switching synchronisation, shortens switching time and reduces dynamic switching losses.
