中文摘要

本文提出了一种基于交错并联升压全桥电路的隔离型三端口直流-直流变换器(TPC),用于混合可再生能源系统。该拓扑采用PWM与移相控制相结合的策略,通过调节相位角和占空比实现多端口功率流的灵活控制,有效提升了系统的集成度与转换效率。

English Abstract

This paper presents the design, modeling, and control of an isolated dc-dc three-port converter (TPC) based on an interleaved-boost full-bridge converter with pulsewidth modulation (PWM) and phase-shift control for hybrid renewable energy systems. In the proposed topology, the switches are driven by phase-shifted PWM signals, where both phase angle and duty cycle are the controlled variables. The ...
