Yu, G. (author), Dong, J. (author), Soeiro, Thiago B. (author), Bauer, P. (author)This paper introduces variable-frequency zero voltage switching (ZVS) modulation strategy for the four-switch buck+boost converter with one operating pattern for the inductor current, i.e., three-segment inductor current modulation control. The proposed modulation scheme guarantees a smooth transition from step-up to step-down or from step-down...conference paper 2023
