摘要：

针对航天器电源系统的应用背景,提出输入输出电流连续的非隔离变换器拓扑.该类变换器具有输入输出电流纹波小的特点,能够显著地减少变换器的输入输出电容容量,特别适合对体积和可靠性要求较高的航天应用领域.在传统非隔离变换器的基本结构基础上,根据电感电流不能突变的原理,通过对开关单元的构造,提出能够实现输入输出电流连续的非隔离变换器拓扑结构和开关单元,通过组合推演得到输入输出电流连续的非隔离变换器.给出该族拓扑的推演过程,以其中一拓扑为例进行仿真分析及实验验证.仿真与实验结果表明所提推演方法的有效性,验证了该类变换器具有输入输出电流连续的特点.
Abstract:

Non-isolated converters capable of continuous input and output current flows were proposed for the application of spacecraft power system. The converters have the characteristics of low input and output current ripple, which can significantly reduce the capacity of the input and output capacitors and are very suitable for spacecraft applications. Based on the analysis of the conventional non-isolated topology and the principle of continuous inductor current flow, topologies and switching units were proposed having both input and output currents flowing continuously through configuring switching units. A family of non-isolated converters was derived by combining these switching units and rotating their terminals. The derivation and the topological analysis were presented. One of the proposed topologies was given as an example and verified by simulation and an experimental prototype, which indicates that the topology can achieve the characteristic of continuous input and output currents.
