A novel implementation of an FPGA-based controller for conducted-noise reduction in randomly switched Dc-Dc converters
Description
This paper proposes a novel implementation of an FPGA-Based controller for conducted-noise reduction in dc-dc converters. The switching noise produced by the converter has been reduced by randomly varying the switching frequency of the converter. Traditionally, the implementation of the switching-mode power supply (SMPS) has been accomplished using analog control circuits. However, the field-programmable gate array (FPGA) is much flexible than analog control circuits, becoming lower cost, and applicable for power supply applications. The implementation of the SMPS has been accomplished using FPGA-based digital controller. Moreover, breadboard has been built-up for testing the effect of using the proposed FPGA-based digital controller for noise reduction in dc-dc converters. Experimental results show that the conducted-noise spectrum has been significantly improved and the noise level has been effectively reduced.
