Abstract

一种兼容可控硅调光器的LED驱动电路，包括：整流模块(111)、电容升压模块(112)、转换模块(115)、电压采样模块(116)、假负载模块(114)、驱动芯片(113)和第一开关管(M1)，电容升压模块(112)至少包括第一电容(CB1)和第二电容(CB2)，驱动芯片(113)用于在所采样的电压低于预设的第一阈值时，通过假负载模块(114)为可控硅调光器提供锁存电流，并关断第一开关管(M1)，在所采样的电压高于预设的第二阈值时，停止为可控硅调光器提供锁存电流，并控制第一开关管(M1)工作，使驱动电压通过转换模块(115)耦合到LED灯组，而且，在上电稳定后，第一电容(CB1)在可控硅调光器导通前为第二电容(CB2)充电。该LED驱动电路提高了可控硅调光器与LED驱动电路的兼容性，在可控硅调光器导通的瞬间不会产生大电流。
