摘要

针对传统Boost升压变换器升压能力不足的问题,提出一种新型非隔离高升压DC-DC变换器,其特点是高电压增益、连续输入电流、开关管和二极管电压应力低、高效率。通过在电路中引入耦合电感,电路可在适当的占空比D下工作,同时通过调节匝数比来保持电压增益。首先对所提变换器的工作状态进行分析,然后推导出元件的电压和电流应力。此外,为了突出所提变换器的性能优势,将其与其他拓扑结构进行比较。最后,通过实验室制作的实验样机验证所提变换器的可行性和有效性。

Abstract

To address the problem of insufficient boost capability of the conventional Boost converter, this paper proposes a novel non-isolated boost DC-DC converter, which features high voltage gain, continuous input current, low voltage stress on the switch and diodes, and high efficiency. By introducing coupled inductors in the circuit, the circuit can operate at a proper duty cycle D while maintaining the voltage gain by adjusting the turn ratio. The paper begins with an analysis of the operating state of the proposed converter. Then the voltage and current stresses of the components are deduced. Furthermore, to highlight the performance advantages of the proposed converter, it is compared with other topologies. Finally, the feasibility and effectiveness of the proposed converter are verified by an experimental prototype fabricated in the laboratory.
