中文摘要:
      为了提高传统Zeta变换器的电压增益、减小电感电流纹波和变换器中磁性器件的体积重量,提出了一种双输入磁集成开关电感Zeta变换器。该变换器是在传统Zeta变换器的基础上增加一路输入,变为双电源输入Zeta变换器,并在结构中用两个开关电感单元分别代替储能电感,对开关电感单元中的电感进行了磁集成。分析了变换器的不同工作模态,推导出变换器的电压增益表达式,分析了电感电流纹波的大小,给出了变换器的磁集成设计方案。与传统Zeta变换器相比,该变换器的电压增益提高了2(1 D)倍,开关电感电流纹波减小了近一半。最后用仿真以及实验对本文的分析进行验证。表明该变换器具有优良的综合性能。
英文摘要:
      In order to improve the voltage gain of the traditional Zeta converter, reduce the volume weight of the inductance current ripple and the magnetic device in the converter, a two-input magnetic integrated switch inductor Zeta converter is presented. Converter is analyzed in the condition of double power input different duty ratio of the work mode, converter of voltage gain in different conditions is deduced expressions, The different working modes of the converter are analyzed and the voltage gain expression of the converter is derived. Compared with the traditional Zeta converter, the voltage gain of the converter is increased by 2(1 D), and the electric current ripple of the switch is reduced by nearly half. Finally, the analysis of this paper is verified by simulation and experiment. It is shown that the converter has excellent comprehensive performance.
