| 摘 要： | 针对常规自主均流法存在动态响应不佳的问题,引入平均电流控制,提出改进式自主均流控制,通过添加电流环为内环并将电压环和均流环并列,改善系统的均流动态性能.本文以Buck变换器并联系统为例,全面地叙述了改进式自主均流技术中三环控制系统的设计过程.最后用三台48V/12V/10A的Buck样机并联实验证明多环路设计的正确性和改进式自主均流法的优越性,从而为改进式自主均流技术的推广应用提供理论基础.

| Abstract: | In order to improve the transient response of current sharing, this paper develops an improved automatic current-sharing technique with average current mode control. Design guidelines of the automatic current sharing control system, including voltage loop, current-sharing loop and current loop, are given. Finally, a prototype with three 48V/12V/10A buck modules is set up and experimental data verify the performance of current sharing. |
