一种具有可变直流母线电压和低共模噪声的紧凑型单相级联三电平AC/DC变换器

This article proposes a new topology technology of a two-stage ac/dc converter with variable dc bus voltage control. The technology is a cascaded combination of a new type of single-inductor-based cascaded three-level totem-pole power-factor-correction (PFC) circuit and a three-level LLC half-bridge converter. Although the existing variable dc bus voltage control strategy based on a two-level ac/d...
