Abstract This article discusses non-isolated, trans-inverse, coupled inductor (CI)-based, soft-switching, high-gain DC-to-DC converter topology for renewable sources.The three-winding CI is utilized to achieve a high voltage gain with a reduced turns ratio.The energy associated with read more the magnetic components is recycled by the passive clamp circuit through diodes, and finally it pushes the output voltage to enhance the converter voltage gain.
Besides, the soft switching performance of the clamping circuit occurs during the turn-off time of the controlled switch, thereby reducing the switching loss and the reverse recovery issue on the diodes.The proposed topology benefits from a here reduced component count and enhances the output voltage gain.Furthermore, the topology performance analysis is carried out using PSIM simulation, and a 250W prototype using a dSPACE controller is analyzed with theoretical expressions.
