Abstract: This article presents a bridgeless isolated and inverted Cuk (BLIIC) converter-based single-stage electrical vehicle battery charging system (SSEVBCS). The suggested BLIIC converter scheme has fewer components than other bridgeless Cuk converter schemes. The converter is garnished with input and output inductances which lessens supply current harmonics like Cuk converter. The advantages of BLIIC converter are eradication of one inductor and a diode which are generally used in bridgeless (BL) converter configurations. SSEVBCS system witnesses the eradication of a rectifier and a low pass filter that reduces the size and losses of the system. Discontinuous current conduction (DCC) mode operation lessens the sensor requirements in comparison to continuous current conduction (CCC) mode. The above benefits make the SSEVBCS system cheaper, more compact, and more efficient. The detailed stability analysis of BLIIC is also included in the paper. Prototype, as well as Simulink results, have been presented to validate the presented SSEVBCS.

Keywords: bridgeless; DCC mode; BLIIC converter.
