The interconnection of basic switching converters to increase power handling capabilities in dc applications has been widely reported in technical literature. This study presents a family of switching step‐up dc–dc converters based on the principle of reduced redundant power processing ( R 2 P 2 ). This principle states that the power transfer from input port and output port on interconnected converters is reduced when a non‐cascading connection is used. As shown in this study, the principle R 2 P 2 is useful for developing new converters. These have wide conversion ratios and quadratic dependence with respect to the duty ratio. In this study, the voltage conversion ratios, average models and steady‐state operating conditions for proposed converters are derived, which are verified by experimental results.
