基于LCC谐振网络的高压钠灯电子镇流器启动方法的研究

Research on Start-up of HPS Electronic Ballast Based on LCC Resonant Network

HPS灯的启动是一个复杂的物理过程。本文通过对LCC谐振网络传输特性的分析,根据滑频软启动的工作原理,提出一种新型变频带滑频的启动方法。该方法可以减小启动过程对元器件的冲击,延长HPS灯的使用寿命,并且具有很好的自适应性。

A novel start-up way is presented based on the Sliding-frequency soft-start theory and the analysis of transmission characteristics of LCC resonant network. With such way, the stress on device during start-up could be reduced, the life of HPS Lamp could be prolonged,and the self-adaptive capability could also be improved.
