Abstract: This article presents a power quality (PQ) improvement bridgeless-switched canonical cell (BL-SCC) converter-based electrical vehicle battery charging system (EVBCS). The advantages of using the BL-SCC converter for PQ purposes are characterised by the removal of extra inductor, two reverse-feeding diodes (usually used in BL converter topologies), and a simple control scheme. By using BL configuration, the bridge rectifier (BR) phase is eliminated from the system, which also eliminates losses related to BR. In this scheme, the BL-SCC converter operates in discontinuous current conduction (DCC) mode that requires fewer sensors as compared to continuous current conduction (CCC) mode. The BL-SCC converter's aforementioned advantages make the EVBC system more affordable, small, and efficient. By using a flyback converter, the EVBC system is electrically isolated, meeting safety requirements. Article also includes the BL-SCC converter's mathematics and thorough stability analysis. BL-SCC converter-based EVBC system's Simulink outputs have been presented to validate the presented EVBCS.

Keywords: switched canonical cell; power quality; bridgeless; flyback converter.
