Abstract

Most of the power of a stacked boost converter (SBC) is transferred to the load directly rather than passing through a MOSFET; that is why an SBC with high efficiency is suitable for aerospace applications. In order to avoid input or output current discontinuity, a bilateral magnetized transformer is employed. The SBC is composed of a pulsating cell, an inductor, an output capacitor and a stacked branch. The structure and generation rules of three kinds of SBCs are proposed, which are named SBC-I, SBC-II and SBC-III respectively. Nine topologies generated according to the generation rules are compared in terms of current characteristics, transfer function, DC magnetic bias and efficiency. In addition, experimental results by a 600 W prototype are given to verify the validity of the theoretical analysis.
