Abstract
Aiming at the traditional communication RF amplifiers problems such as high cost and low efficiency,a single-stage AC-DC high gain step-down LED driver and its hybrid visible light communication(VLC)modulation control strategy are proposed to meet low-voltage output and VLC of LED applications.The low-ripple step-down Cuk combined switched capacitor(SC)and synchronous rectification(SR)Buck are integrated into a single-stage driver.The hybrid VLC control strategy is based on the theory of binary phase shift keying(BPSK),the LED lighting level is controlled by the average output current,and the data communication modulation is realized by the phase change of the output current ripple.The proposed circuit and hybrid control strategy are analyzed in detail,and the key parameters of the proposed circuit are designed.Finally,the computer simulation is carried out,and an input of 185～265VRMS and constant current output of 1A/25W experimental prototype is set up.The simulation and experimental results have been obtained to show that the circuit can realize high gain step-down,the functions of hybrid LED lighting control and VLC modulation,which verifies the effectiveness of the proposed driver and hybrid VLC modulation control strategy.关键词
