Delta sigma signal processing (DSSP) is a novel signal processing approach based on ΔΣ-bitstreams. In order to fully utilize the advantages of DSSP, a high bandwidth three phase hysteresis modulator was presented in literature. This modulator directly processes high frequent ΔΣ-bitstreams. A detailed description of the operation modes, the overmodulation range close to the voltage limit and the voltage...
Delta Sigma (ΔΣ) analog digital converters are usually comprised of an analog modulator and a digital low pass filter. These converters are used for phase voltage and phase current measurement in control loops. A new approach, the delta sigma signal processing (DSSP), directly processes the high frequent ΔΣ-bitstream. Due to the high frequent sampling rate of the DSSP, sampling effects can be neglected...
