A novel integrated converter for electric vehicles (EVs) is proposed in this work. For battery charging operation, the proposed converter system enables a complementary deployment of the utility grid and a solar photovoltaic (PV) system. Since both sources (acting one at a time) utilize the same converter, the developed charging system therefore has a smaller number of components. In addition, an inductor voltage detection (IVD) technique has been incorporated to correct the power factor in continuous conduction mode (CCM), which eliminates the need for a current sensor for power factor correction (PFC). The proposed system operates for all the modes required for an EV e.g., charging, propulsion (PRN) and regenerative braking (RBG). In charging mode (with either grid or solar PV), the proposed system operates as an isolated secondary ended primary inductance converter (SEPIC) converter. In PRN and RBG modes, it operates as a boost converter and a buck converter, respectively. Details of all these modes are described in the paper, along with the design of the components.
