Digital current mode and voltage control for the dc-dc step-up converter based on the FPGA technology

摘要

This paper introduces a digitally performed voltage and current control mode for dc-dc step up converter based on FPGA technology. The voltage and current measurement was realized by using A/D converters as peripheral units of the FPGA system. Special attention was performed with current measurement and its A/D conversion due to the used predictive current mode algorithm which enables the fully digitalization of the whole control processes.
