The grid-connected electric vehicle charging stations are being integrated into renewable energy for preserving the conventional energy resources as well as to ensure sustainable development of the society. In addition to the effortless charging, the sudden demand variations in the grid can be met by the renewable energy storage system in the charging stations. The main challenge in this concept is the unstable nature of renewable energy. As the energy storage system of charging station is directly connected to the renewable energy source like a solar panel, according to the variable and deficient input power condition, the converter should supply a regulated output at the required magnitude. If a conventional converter is used for this purpose, the charging efficiency will be poor for higher gain conditions. This article presents a hybrid forward-boost converter to overcome this challenge. By maintaining the power transfer efficiency higher, the gain can be varied to supply a regulated voltage, even for very low input conditions in this proposed topology. The maximum overall efficiency of 95% is achieved for a variable input condition of 30–50 V to provide an output voltage of 170 V. The concept is validated by implementing a 150 W hybrid converter. © The Institution of Engineering and Technology 2019.
