Fully Digitally Controlled Voltage Regulator Based on FPGA

This paper presents the implementation and test results of a fully digitally controlled voltage regulator (VR) designed for high-performance microprocessors. The VR consists of two print circuit boards (PCB). The first PCB, referred to as the power board, is responsible for voltage conversion and incorporates components such as main power supply, output capacitor, and electronic load. The second PCB, referred to as the control board, is dedicated to signal sampling and digital control, including analog-to-digital converters (ADC) and field-programmable gate array (FPGA). The paper provides a detailed description of the implementation of the VR and presents the test results.
