| Abstract |
The delta modulation technique permits an accurate tracking of an arbitrary reference. Spectrum of
the current going through an inductive load shows a very low THD. Moreover, notches are located
around 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. |
