Abstract
A single stage electric vehicle battery charger with an isolated bridgeless (BL) Cuk-SEPIC converter is developed in this work. The design of this converter is ensured in discontinuous conduction mode with intrinsic power factor correction (PFC) at AC mains. This topology offers the advantage of reduced number of components with improved efficiency due to integration of Cuk and SEPIC converters during the individual half cycle. The presence of output inductor at Cuk converter side also smoothens the output current, as compared to SEPIC converter used for both cycles. A prototype is designed and developed for a battery load of 48V/100Ah to demonstrate the unity PF based charging. The efficacy of charging is tested in constant current (CC) and constant voltage (CV) modes to validate the performance at rated and different supply voltages. Different power quality parameters are observed to be within the IEC 61000-3-2 standard.
