中文摘要

本文探讨了利用Z源和准Z源逆变器拓扑实现电子镇流器,旨在通过单级变换取代传统的多级架构,以获得高功率因数并优化灯具运行。研究重点在于减少控制器数量及简化电路拓扑,提升能量转换效率。

English Abstract

Electronic ballasts are implemented for obtaining a high power factor and a good operation of the lamp; these goals are reached traditionally by implementing multiple stages. On the first stage, a unity power factor is obtained and the second stage is designed in order to feed properly the lamp. Different topologies have been studied not only for decreasing the number of employed controllers and s...

该文献研究的Z源/准Z源拓扑具有单级升降压特性,虽然其应用背景为电子镇流器,但该拓扑在光伏逆变器或小型储能变换器中具有潜在的借鉴意义。阳光电源目前的组串式逆变器和户用储能系统多采用成熟的Boost+逆变两级架构,以追求高效率和高可靠性。虽然Z源拓扑能简化电路,但其电感/电容应力较高。建议研发团队关注该类拓扑在特定低功率、高功率密度需求场景下的应用潜力,作为未来技术储备,以优化小型化逆变器或充电桩的电路设计。
