Abstract
- This article presents an interleaved buck-type rectifier with pseudo-dc-link capacitors featuring automatic current balancing, soft-switching operation, efficient ac-dc conversion, and tight output regulation. The ac-input-current-synchronized modulation scheme that hybridizes for cycle-by-cycle phase-shift and duty ratio adjustment is adopted for zero-voltage switching (ZVS) operation and output regulation. In addition, the pseudo-dc-link capacitors facilitate the convergence and current balancing between output inductors. Mathematical models are provided to quantitatively describe the mechanism of current balancing, steady-state performance, and dynamic response. A lab prototype is built, and the experimental results are provided to verify the features. [ABSTRACT FROM AUTHOR]
