High Frequency Pulse Width Modulation Converters

Author

Abstract

The delta modulation technique permits an accurate of an arbitrary reference. Spectrum of the current going
through an inductive load shows a very low THD. Moreover, notches are located aroun d the sample frequency
multiples, which is of interest for converters without output low-pass filter. In this paper, we demonstrate that the
delta modulator structure can be easily implemented when regulating the converter output current going through
an inductive load. Then, we propose a mean for computing the load current spectrum using the Laplace and
Fourier transforms.
