Conventional deadtime compensation relies on information from a standard current sensor, which may not capture current ripple behavior accurately due to latency, frequency response, and noise limitations. The ZCD and hardware logic circuits operate at extremely high speed, and the feedforward compensation algorithm has minimal computational requirements. Simulation results show a significant improvement in load current total harmonic distortion (THD). The proposed circuit was constructed, and hardware testing with a SiC inverter showed similar performance to simulation.}, journal={2022 IEEE ENERGY CONVERSION CONGRESS AND EXPOSITION (ECCE)}, author={Kercher, Michael and Yu, Wensong and Husain, Iqbal}, year={2022} } @article{rahman_kercher_yu_husain_2021, title={Comparative Evaluation of Current Sensors for High-Power SiC Converter Applications}, ISSN={["1048-2334"]}, DOI={10.1109/APEC42165.2021.9487428}, abstractNote={An evaluation procedure for comparative analysis of various current sensor technologies is proposed in which performance parameters such as latency and resolution are measured under realistic conditions for a high-power SiC converter. Testing techniques are developed to allow fair comparison between dissimilar sensor types. Experimental data is given for an open-loop Hall Effect sensor and two types of shunt-based sensors utilizing Delta-Sigma modulators.}, journal={2021 THIRTY-SIXTH ANNUAL IEEE APPLIED POWER ELECTRONICS CONFERENCE AND EXPOSITION (APEC 2021)}, author={Rahman, Dhrubo and Kercher, Michael and Yu, Wensong and Husain, Iqbal}, year={2021}, pages={2206–2210} }
