Abstract
This article proposes a single-phase bridgeless Cuk-derived power factor corrected (PFC) converter with a smaller number of components is proposed for on-board EV charging applications. The distinctive feature of this proposal is to design and operate the output inductance of the converter in discontinuous current mode for the whole power range to achieve the PFC naturally on the AC grid, which eliminates the need to sense the input voltage and current. This reduces the cost of the converter and improves the power density as well as the robustness of the converter against high frequency disturbances. Thanks to a sophisticated circuit design and the optimization of the components, the converter achieves a considerable reduction in the total number of components and thus contributes to cost efficiency and a compact design. The control of the converter is very simple in operation and easy to implement with only a single sensor-based voltage control loop. The voltage stress of the semiconductor components of the proposed converter is lower compared to the traditional converter. It also contains an alternative direct current source from a fuel cell. This research represents a significant leap forward in the field of EV charging technology. The reduced number of components increases reliability, lowers costs and contributes to the development of more sustainable and efficient electric transportation.
