  • the invention is based on the knowledge that peak-valley values of an intermediate circuit voltage at an intermediate circuit capacitor of the inverter typically have pronounced maximum values and a reduction in the carrier frequency, on the one hand, an increase in the peak-valley value and, on the other hand, a reduction in switching losses during switching operation the switching elements be effective. Since the maximum carrier frequency operating point can be assigned to such a maximum value of the peak-valley values, lower peak-valley values beyond the maximum value open up scope for reducing switching losses by reducing the carrier frequency as a function of the operating point. This advantageously enables more efficient operation of the inverter without having to increase the capacitance of an intermediate circuit capacitor.
