中文摘要

随着可再生能源、交通电气化及微电网的发展,对具备灵活直流母线调节能力的双向DC-DC变换器需求日益增长。本文提出了一种新型三电平Buck-Boost变换器,通过集成平面耦合电感,在实现高效功率变换的同时,有效抑制了共模噪声,适用于无需电气隔离的直流电压调节场景。

English Abstract

The demand for a bidirectional dc–dc converter with a flexible dc bus is driven by the fast development of renewable energy system, transportation electrification, and microgrid. In order to accommodate different dc bus, two-stage ac–dc–dc architecture has been widely used, and the dc output regulation was handled by a rear-end dc–dc converter. If the galvanic isolation is not required, the four-s...
