Design and Simulation of a Modified Single-Ended Primary- Inductor Converter for Use in Charging Low Voltage Battery Applications with the Approach of Increasing the Power Factor of the Converter

In this paper, the goal is to achieve a high-reduced gain for low-voltage electric vehicle charger applications using a modified SEPIC without a diode converter. The non-bridge-free structure, as well as the simultaneous switching of switches, reduces control complexity. The extensive converter reductor is achieved through the switched inductor structures, which allows for the battery charge profile needed for low-voltage batteries. The function of the discontinuous current states not only facilitates the ability to correct the intrinsic power coefficient on the network side, but also reduces the size of the magnetic components. The DICM's operation also provides zero-current for switches and zero currents for high frequency diodes, thus minimizing losses associated with reverse diode recovery transfers.
