摘要

由于LED具有类似二极管的特性，它应该由恒流(CC)源驱动。直流电源的冗余设计不同于传统的直流电源。本文讨论了不同的冗余解决方案。基于小信号模型分析了N+1冗余系统的稳定性问题。提出了相应的解决方案，并通过实验结果进行了验证。

High reliability driving solution for solid state lighting

LED should be driven by a constant current (CC) source due to its diode-like characteristic. The redundancy design for CC drivers is different from that for conventional CV power supplies. Different redundancy solutions are discussed in this paper. The stability issue for N+1 redundancy system is analyzed based on the small signal model. Related solution is suggested and verified by experimental results.
