A novel topology of delta modulation technique for improving the power factor of AC-DC converters

This paper presents a proposal for a new algorithm and a modification for variant of delta modulation technique that is used for generating the control signals for main devices of PWM converters. Moreover, modeling and a simulation is developed for this modified variant of delta modulation technique. The effect of this algorithm is tested by using the developed simulation of quasi-stationary states and transients. The simulation has shown to be effective to test the improvement of the performance of the three-phase converters.
