Unlike conventional voltage sensing (CVS) methods, EDAF has better delay performance and significantly enhances the sampled signal quality with pulse signal input. EDAF utilizes the features of pulse signals and the event capture module in the microcontroller to timestamp both edges of the pulse signal accurately for the proposed algorithm calculation. This circumvents the need for high-performance analog-digital converters (ADCs) and low-pass filters (LPFs), bolstering overall performance. The principle of operation and analysis of the EDAF is comprehensively detailed. Computer simulation is provided to verify the performance of the proposed EDAF method.edge-capture | filter | switching pulse signals | voltage measurement[SDGs]SDG7conference paper10.1109/IFEEC58486.2023.104585752-s2.0-85189752924https://api.elsevier.com/content/abstract/scopus_id/85189752924
