an inverter is proposed for providing an inverter output signal scalable in frequency . the inverter has a controller for controlling frequency of the inverter output signal according to a predefinable value . in order to generate a signal having a frequency value prescribed for the inverter output signal , the controller initiates a time delay of signals and superimposes the signals onto the signal having the frequency value prescribed for the inverter output signal . a low - complexity inverter concept for high voltages or high power is thus provided
