Abstract
In order to realize the high quality electric energy for constant current regulator , the lighting constant cur-rent regulator based on a king of current source PWM rectifier was analyzed in this paper .The working principle and mathematical model of the light constant current were analyzed firstly , and the steady-state solution of the circuit equa-tion was solved by large signal model , and the decoupling control method based on feed forward control was designed for regulator, as a result, the steady-state error of control loop can be decreased effectively , and constant current out-put can be realized , meanwhile , the harmonic content of output current and line side current can be also decreased ef -fectively .Simulated by MATLAB/Simulink , and compared with the traditional light regulator , the direct component of regulator had small ripple wave , THD in line side current was reduced from 2.71% to 1.88%, and the harmonic content of the output current from the load side was reduced from 1 .24% to 0 .15%.The performance of the improved type light regulator is better than that of the traditional light regulator .关键词
