摘　　要：针对采用智能电致发光(S.E.L)技术的交通标识电源输入电压低及驱动电压频率高、幅值大的问题,提出了一种基于带软开关的Boost电路与E-class电路级联的高升压比高频逆变驱动电路。利用S.E.L材料在驱动频率下高阻抗特性,采用带电流源特征的E-class变换器,实现对负载两端电压的提升。所提变换器在满足负载所需驱动频率及驱动电压时,可同时实现两级变换器的零电压导通。最后,通过一台升压比为14的样机验证了分析的正确性。Aiming at the problems of low input voltage and high demand on driving voltage frequency and amplitude of the traffic sign power supply using smart electroluminescent(S.E.L)technology,a high rise ratio high frequency inverter drive circuit based on the cascade connection of the Boost circuit with soft switching and the Eclass circuit was proposed. Utilizing the high impedance characteristics of S.E.L material at the driving frequency,the E-class converter with current source characteristics was used to achieve the high increase of the voltage across the load. The proposed converter could realize the zero voltage switching(ZVS)of the two-stage converter at the same time when the driving frequency and driving voltage required by the load were satisfied. Finally,a prototype with a boost ratio of 14 was used to verify the correctness of the analysis.
