Abstract
In recent years, based on the notion of switched-inductor, DC-DC converters have been used in various applications, including DC microgrids, renewable energy integration, and high voltage light-emitting diodes. This publication presents a unique double-switch switched-inductor converter with minimal switch voltage stress for renewable energy conversion. The suggested converter is formed from different design arrangements of the traditional switched-inductor converter to reduce voltage stress and increase performance. The converter's non-ideal model and several operation modes depending on inductor current characteristics and output voltage ripple are described. The suggested topology is extended to attain a more significant voltage gain. The design and comparison of the proposed converters with recent converters are discussed. Finally, experimental prototype results are presented for a load power of 500 W to validate the proposed converter configuration. The efficiency curve is shown for various power and input voltage conditions. The loss breakdown characteristics for a load power of 500 W are provided.
