A novel method for hybridization of super lift luo converter and boost converter for electric vehicle charging applications

ABSTRACT

The demand for electric vehicles (EVs) has increased dramatically in recent years, making it increasingly challenging to keep up with the demand for charging infrastructure. However, conventional power converters (DC–DC converters) have drawbacks such as a high component count, low voltage gain, low efficiency, and high cost. A new DC–DC multiport converter has been proposed to address these challenges by hybridizing a Super-lift Luo and Boost Converter (SLBC) with Photovoltaic (PV) and battery sources as dual inputs. The proposed Dual-Input Dual-Output (DIDO) converter offers significant advantages by super-lifting the input voltage while producing two step-up voltages, one by the Luo converter and another by the Boost converter. The SLBC uses simple structures without any additional electric circuits or transformers to generate high voltage gain and high power efficiency. To evaluate the performance of the proposed SLBC, the converter operation has been analyzed under steady-state and Continuous Current Mode conditions, and a comparison with other similar configurations has been conducted to demonstrate its benefits. Simulation and experimental results have shown that the proposed SLBC offers a considerable reduction in conduction losses compared to other SLBC converters in similar situations. Furthermore, the SLBC system provides 1.2 kW output at the charger side with 94.8% efficiency, making it a viable option for powering various EV components, including the charger, motor, lighting, and audio system, with variable voltages.
