Abstract :This paper introduces a hybrid converter topology based on boost and push-pull configurations for electric vehicle (EV) charging applications. In the proposed converter structure, an RCD snubber circuit is used to reduce the thermal losses in power electronic devices and the peak voltages in individual components. Thus, by reducing the peak voltages on the switching components, the efficiency of the proposed hybrid converter structure is increased. The proposed topology aims to reduce the peak voltage and voltage stress on the switching components and to reduce the losses by reducing the transformation ratio of the transformer in the push-pull converter. In addition, another aim of the proposed topology is to provide improved continuous and rectified output current, thus extending the system\\\'s life in applications. Moreover, the proposed converter is tested in continuous conduction mode (CCM) and compared with similar existing designs. To verify the mathematical analysis, the 500 W output power converter designed using the proposed hybrid estimation structure is tested in a simulation environment. The analysis yielded continuous and direct current. As a result of the simulation analysis, a significant reduction in the peak voltages and voltage stresses on the switching elements occurred with the proposed converter topology. In addition, by reducing the transformer turns ratio, transformer losses are reduced.
