Abstract: A control system for semiconductor switches, the control system (CTRL) being configured to calculate an estimate of the instantaneous dissipation power of at least one semiconductor component unit (SU1) during an analysis period, whereby the at least one semiconductor component unit (SU1) includes at least one semiconductor switch (S1), and the instantaneous dissipation power includes the conduction losses and switching losses of the at least one semiconductor component unit (SU1).
