摘要:
双向DC-DC变换器采用双向半桥变换器拓扑结构,首先阐述了双向半桥变换器的工作原理,并分析了电源的并联特性及自主均流法的工作原理,给出了参数设计方法.以Buck/Boost变换器并联系统为例,采用PID控制方式,应用Matlab对该模型进行了仿真,将仿真结果与未加均流方法进行比较,结果表明Buck/Boost变换器能实现能量的双向传递并且能很好地实现均流,从而验证了分析的正确性,为双向DC-DC变换器自主均流技术的推广应用提供仿真经验.
Abstract:
This paper describes the topological structure and principle of the bidirectional half bridge converter. The authors firstly made a general analysis of the characteristics of parallel current and the general principle of automatic currentsharing technique, then gave the method of parameter design. The parallel Buck/Boost converter was introduced and the model of it was simulated with Matlab by PID control method. The analysis and simulation results were compared with noncurrentsharing control method, showing that the power can flow in either direction and the dynamic characteristic of threeloop control technique is better. The results show that the analysis is right. It provides simulation experience for the application of the parallel bidirectional DCDC converters.
