Abstract
Based on the combination of boost Boost circuit and improved synchronous rectification buck Cuk circuit,a DC/DC combined LED driver circuit for visible light communication is proposed.The high conversion efficiency is achieved by the boost Boost circuit with lower switching frequency processes most of the power(LED lighting power).The improved synchronous rectification buck Cuk circuit with high switching frequency modulates communication signals to achieve high communication performance.A detailed analysis of the working principle and process of the proposed circuit is conducted.A binary phase shift keying modulation strategy is adopted for the design.Finally,through computer simulation analysis and experiments,the feasibility and effectiveness of the proposed combination circuit and BPSK communication modulation strategy are verified.关键词
