摘　　要：采用TEA1750第三代绿色开关电源(SMPS)控制器IC,设计了110 W大功率LED驱动电源。该电源具有90V AC^280V AC输入和大约80V/1.37A输出的驱动能力。同时,它还具有功率因数校正(PFC),准谐振和谷值检测的优点,并提供了低输入电压保护,过电压保护,过温和过电流保护。在正常工作条件下,效率高达85%以上,功率因数在0.94以上。By TEA1750 third-generation green switching power supply (SMPS) controller IC, designed the 110W power LED drive power. The power supply has 90V AC^280V AC input and output drive capability of about 80V/1.37A . It also has a power factor correction (PFC), the advantages of quasi-resonant and valley detection , and provides a low input voltage protection, over voltage protection , over-temperature and over-current protection. Under normal operating conditions, the efficiency up to 85%, power factor of 0.94 or more.
