Abstract
High gain DC–DC converters have become increasingly important in several applications including renewable energy systems, electric vehicles, and DC microgrids because of the necessity of converting low input voltages to high output voltages efficiently. This study focuses on the design and performance analysis of a high gain DC–DC converter that operates in the Continuous Conduction Mode (CCM). The use of CCM guarantees low current ripples, efficient energy transfer processes, and stable operations. The proposed converter utilizes combinations of inductors, capacitors, diodes, and controlled switches in order to ensure the conversion of low input voltages to higher outputs at a significantly high voltage gain without employing extremely high duty cycles. The converter topology has been designed to optimize the energy transfer and storage process by taking advantage of the various operating modes. The proposed converter design has been able to reduce the voltage stresses applied on the switching components hence improved reliability and better performances. Due to its high voltage gain capability, the suggested converter can be employed in applications such as photovoltaic systems and battery operated systems, which require step-up conversions. Simulations demonstrate the performance of the proposed converter in terms of efficiency and continuous currents.
