摘要： 目的：高压钠灯(HPS)由于其成熟性、可靠性、高光效长寿命和低成本的特点广泛应用于道路照明。LED被认为是下一代光源，其光效不断提高，有更好的显色性和超长寿命。这两种光源可能会共同存在很长时间。大规模应用中，需要研发生产大量不同型号镇流器，使用和安装也需要用户学习掌握不同应用知识。工业界里的一种方法是通过设计多功能产品来减少产品类型，简化研发和生产管理，降低应用难度。类似的，对高压钠灯和LED具有兼容性驱动功能的驱动器，也可作为一种选择来适应这种多光源共同应用的情形，使得应用更为便捷。但是由于传统高压钠灯与LED的光源特性以及驱动技术完全不同，研究其兼容性驱动技术将富有挑战性。本文研究这一技术，对解决照明应用的多光源现状具有实用价值，也可作为一种思路启发其他类似应用。
创新点：通过分析用于高压钠灯的LCC谐振腔驱动技术与用于LED的LLC谐振腔驱动技术，结合两者提出一种可变谐振腔用于一种驱动器中来驱动高压钠灯与LED。驱动器根据对光源的检测，采用数字控制技术，可将谐振腔变为LLC或者LCC结构，以适应不同光源的负载特性。该技术保留了传统HPS和LED驱动器的软开关特性以及调光功能，实现了对不同光源的兼容性驱动。
方法：研究高压钠灯镇流器中LCC谐振变换器与LED驱动器中的LLC谐振变换器的拓扑与各种工作阶段，分析它们的共性，提出新的可变谐振腔。并根据两种光源驱动特点，分析谐振腔关键参数与性能参数的关系，给出可变谐振腔的设计方法。本文所提技术用实验方法进行了验证。
结论：本文提出的可变谐振腔可实现对高压钠灯与LED的兼容性驱动，并保留传统驱动技术软开关与调光的特性。这种技术使得适应多光源应用场合的兼容性驱动器成为可能。

Abstract: High pressure sodium (HPS) lamp has been widely used in street lighting applications because of its maturity, reliability, high lighting efficiency, long life-time, and low cost. Light emitting diode (LED) is expected as the next generation lighting source due to its continuously improving luminous efficacy, better color characteristic, and super long life-time. The two lighting sources may coexist in street lighting applications for a long time. A novel HPS and LED compatible driver is proposed which is rather suitable and flexible for driving HPS and LED in street lighting applications. The proposed driver combines the LLC and LCC resonant circuits into a flexible resonant tank. The flexible resonant tank may change to LLC or isolated LCC circuit according to the lighting source. It inherits the traditional HPS and LED drivers’ zero voltage switching (ZVS) characteristics and dimmable function. The design of the proposed flexible resonant tank considers the requirements of both HPS and LED. The experiments of driving HPS and LED on a prototype driver show that the driver can drive the two lighting sources flexibly with high efficiency.
