Abstract

The measurement units based on the voltage-to-frequency conversion for voltage and current control in step-down DC-DC converter is considered in this paper. This approach enables the digitalization of the both control loops; i.e. voltage and current control loops. The voltage current measurements are performed by using appropriate voltage control oscillators (VCO) and counters, which represent the digital “integrators”, and enables full digitalization of current and voltage control loop.
