Summary In this paper, two cascaded buck‐boost nature converters are developed; one converter is capable of producing high step‐up gain, and the other converter addresses high step‐down gain. In proposed converters, for a given voltage gain, two distinct duty ratios are possible due to their ability in handling complementary switching schemes. This feature is effective for voltage‐sensitive applications like LED systems. The operation principle, steady‐state analysis, and the design of the passive components for each switching scheme are presented for the proposed converters. Comparative analysis with competitive converters profound the merits of the proposed converters in terms of voltage gain and the continuous nature of the output. Experiments are conducted on both proposed converters for simultaneous and complementary switching schemes, and they validate the theoretical steady‐state performance.
