中文摘要：

发光二极管（LED）效率高、寿命长、无污染,在照明领域的应用日趋广泛,但伏安特性的非线性和温度敏感性增加了LED的高性能控制的难度。设计了一种新型的LED驱动电源,主电路采用反激（Flyback）变换器,引入单周期控制（OCC）技术和条件作用技术积分限制抗饱和（Anti-windup）算法分别进行LED的恒压恒流控制,并实现PWM调光功能。仿真结果表明,所设计的电源可有效提高系统的动态品质、稳态精度和抗干扰性能。

英文摘要：

Light-emitting diode （LED） is used more and more widely in lighting due to its high luminous efficiency, long service life, no pollution and other advantages. But the high performance control of LED is limited by its nonlinear volt-ampere characteristics and temperature sensitivity. In this paper, a new LED driving power was proposed. The flyback converter was adopted as the main circuit, one cycle controller（OCC） and conditioning techno!ogy integration limit anti-saturation（Anti-windup）controller were designed to realize the constant voltage control and constant current control of the high-power LED respectively, the dimming function based on PWM could also be achieved. The simulation results show that using this driving power supply, the dynamic performance, steady state accuracy and anti-disturbance performance of the system were improved effectively,
