Experimental comparative study of controllers for a DC-DC step-up converter

Abstract

This report presents the design, implementation and control of the DC-DC boost converter. The details are described in the report. The boost converter system with its associated sensing and control circuitries was built. The feedback controllers implemented using analog devices are the proportional-integral controller and the multi-loop controller. A comparative study was carried out to compare the controllers’ dynamic performances and flexibilities under different operating conditions. Experimental results are also presented to highlight the features of each controller.
