摘要:在高电压输入大电流输出的场合,输入串联输出并联组合变换器得到了越来越广泛的应用。本文在分析输入串联输出并联变换器基本原理的基础上,分析了一种能够实现各模块相互独立控制的输入均压控制策略,实现无互联。并通过建立系统的小信号模型,设计控制器的参数。为了验证控制策略的有效性,本文以由两个模块组成的系统为例,搭建了仿真电路和实验平台进行验证。

Research on Input Voltage Sharing Control Strategy for Input-Series Output-Paralleled DC Converter
Abstract:In the case of high voltage input and large current output, the Input-Series Output-Parallel converter has been more and more widely used. In this paper, based on the analysis of basic principle of the Input-Series Output-Parallel converter,an input mean voltage control strategy which can realize the independent control of each module is analyzed.And by establishing the system of the small signal model, to design the parameters of the control strategy. In order to verify the effectiveness of the control strategy, this paper takes a system composed of two modules as an example, and establishes the simulation circuit and experimental platform for verification.
