摘要

运行稳定性和鲁棒性通常是实际实现系统的主要标准。这在LED照明应用中尤其重要，其中电压调节器用于控制非线性LED负载的电流。此外，即使是同一品牌的led，负载的参数也会随着温度和仓的变化而显著变化。LED驱动控制系统必须有效地补偿上述干扰。在本文的范围内，固有稳定性(开环频率响应)和闭环系统的稳定性的几种转换器拓扑结构用于LED照明的分析。

Evaluation of stability of several LED drivers in smart lighting applications

The operation stability and robustness are usually the main criteria for the practically implemented systems. This is especially critical in LED lighting applications, where voltage regulators are used to control current of nonlinear LED load. Also the parameters of the load significantly changes with the temperature change and bin change even for the same brand LEDs. The control system of LED driver must effectively compensate the above mentioned disturbances. In the scope of this article the inherent stability (open-loop frequency response) and the stability of closed loop-system of several converter topologies used in LED lighting applications are analyzed.
