Digital Current Mode Control for Buck-Converter Based on Average Inductor Current Measurement

This paper introduces a digitally performedcurrent mode and voltage control for the dc-dc step downconverter based on voltage to frequency converter where theaverage values of inductor current and output voltage areobtained. These current and voltage measurement arerealized by the voltage control oscillator (VCO) andcounters (digital integrator). Such an approach enables fulldigitalization of current and voltage control loops
