Mitigation of Voltage Harmonics in Grid‐Powered EV Fast‐Charging Station Using MLI‐Based DVR
ABSTRACT This research article demonstrates the protection of point of common coupling (PCC) by mitigating voltage harmonics produced by electric vehicle fast‐charging station (EVFCS) using multilevel inverter (MLI) based dynamic voltage restorer (DVR). The DVR is a series‐connected voltage‐compensating device. A five‐level T‐type inverter is used as voltage source inverter (VSI) of DVR. Three Li‐ion batteries, each rated as 48 V, 10 Ah, 5 A, are connected to the common DC‐bus configuration consecutively. The DVR enhances the quality of PCC voltage in terms of voltage harmonics as per the IEEE 519 standard, thereby protecting the other loads connected to the PCC. Also, the various characteristics of EVFCS are determined experimentally, which exhibit the smooth operation of the grid‐powered EVFCS by the closed‐loop current‐controlled DC‐DC buck converter. Lastly, the experimental results strengthen the results of simulation and prove the main contributions of this research work.
