Research on constant current regulator in navigationallighting aid
Constant current regulator is the equipment for different brightness adjustment in navigational lighting aid,this paper aimed at bigger ripple wave and higher costs in traditional navigational lighting aid the proposed a new type navigational lighting aid,the DC-DC transformation model was used in contravariant part of the constant current regulator,the output of the regulator can get constant direct current, thus the cost of after end in traditional regulator can be decrease in the case of satisfaction of requirement of power supply for load. In control aspect, according to the solution under the DC-DC traditional model in DC-AC circuit.,instantaneous positive power theory combine with the voltage current double loop control was used in this topology,this model has advantage of decrease the ripple wave of output voltage,ripple wave of output voltage is from 2% to 1%.and was experiment in MATLAB/SIMULINK,the result concluded that constant current regulator can get output current with 1% ripple wave ,current of AC Side has small distortion , THD is only 2.7%.
