八相降压变换器的鲁棒ZAD滑模控制

This paper describes the design, robustness analysis, and implementation of a zero average dynamics sliding mode control (ZAD–SMC) for a multiphase step-down converter. The ZAD–SMC operates at fixed switching frequency and allows to implement an interleaving technique providing current-ripple cancellation at the converter output. Moreover, the proposed control structure, which is based on a master...
