This study attempts to identify the modulation parameters of a Delta modulator. A novel technique of implementing the Delta modulator by a microcomputer Delta Modulators can be significantly reduced by allowing online parameter variation and synchronous operation, which can be varied during constant and variable frequency operation of the three-phase Voltage Source Inverter (VSI) so as to improve the performance in terms of harmonic content and fundamental voltage availability. Test results show that dual-slope and dual slope-variable window width operations provide considerably higher fundamental voltage while maintaining the spectra of dominant harmonics to occur at higher frequency range.
