In this paper a novel switching ripple mitigation technique is developed and applied to the double dual boost converter (DDBC). Under the proposed scheme, an unconstrained selection of the voltage-gain-range at which the input-current ripple is mitigated is enabled. Furthermore, as an emerging advantage of this new strategy, we demonstrate that the elimination of the output-voltage ripple can be also achieved. The simultaneous input-current- and output-voltage ripple mitigation under a fixed but otherwise arbitrary selection of the converter's input-to-output voltage gain is the main contribution of this work, which is in sharp contrast with current switching techniques that are exclusively focused on input-current ripple cancellation at constrained duty cycles. Theoretical and experimental evidence is presented to validate the proposed scheme.
