基于双二进制编码单比特Delta-Sigma调制器的非反相Buck-Boost DC-DC变换器

This paper presents a delta-sigma modulation (DSM) control scheme for noninverting buck-boost (NIBB) converter that features a duobinary encoding for four power switch controls. The proposed scheme converts the single-bit output of the modulator into a 1.5-b signal to enable a three-phase operation comprising the charging, bypassing, and discharging phases. This control method reduces both switchi...
