Digital Current Mode Control for Buck-Converter Based on Average Inductor Current Measurement
Abstract
This paper introduces a digitally performedcurrent mode and voltage control for the dc-dc step down
converter based on voltage to frequency converter where the
average values of inductor current and output voltage are
obtained. These current and voltage measurement are
realized by the voltage control oscillator (VCO) and
counters (digital integrator). Such an approach enables full
digitalization of current and voltage control loops.
