Abstract
Converter and method for controlling a converter with power semiconductor switches, having a filter () which is connected to the power semiconductor switches and having a drive circuit () which is connected to the power semiconductor switches for the purpose of modulation, wherein, as a result of the modulation, a fundamental at a fundamental frequency (fGS) is generated in a passband (P) of the filter (), modulation products are generated in a first frequency band (FB), in a second frequency band (FB) and in an intermediate frequency band (ZFB) which is formed between the first frequency band (FB) and the second frequency band (FB), the modulation products in the intermediate frequency band (ZFB) are reduced in comparison with the modulation products in the first frequency band (FB) and the modulation products in the second frequency band (FB); and the intermediate frequency band (ZFB) is generated, in a resonant range (R) of a resonant frequency (fres) of the filter (), between the passband (P) and an attenuation range (D) of the filter (). A converter having an output-side sinusoidal filter whose dimensions have been reduced is thus obtained.
