中文摘要：
文章提出了一种适用于便携式设备的多路输出变换器。该变换器采用单个电感即可实现非隔离的多路正负电压输出,详细介绍了该变换器的工作原理及其占空比的控制方式,研究了该变换器存在的交叉调节问题,提出了改善交叉调节的控制方法。在此基础上论述了两种衍生电路,提高了电路的应用性能。文中利用Pspice和Matlab对该变换器的工作原理进行了仿真验证。
英文摘要：
A multi-outputs converter topology applicable for portable instruments is put forward. Non-isolated positive and negative voltage multi-outputs are achieved by using only one inductor. Cross regulation of the converter is studied and the technique which can reduce the influence of cross regulation is presented based on introducing the operating principle and control technique. Two derived topologies which can improve the performance of the converter are brought out. Key principles of the paper are verified by Pspice and Matlab simulations
