【摘要】 提出了单原边绕组电流源型双向多输入全桥DC/DC变换器的拓扑生成方法,在所生成的电路拓扑中,变压器只有一个原边绕组,与多原边绕组相比,简化了系统结构、减少了元器件数量、降低系统的成本。可以实现单独或同时向负载供电,以及负载反馈能量的作用。以Boost型单原边绕组双向双输入全桥DC/DC变换器为例,详细阐述其生成方法及工作原理,最后通过仿真实验验证理论分析的正确性。更多还原

【Abstract】 In this paper,the synthesization of multi-input current-fedbidirectional full-bridge DC /DC converter with single primary winding topologiesis proposed. Compared to the converters with several primary windings,this converter has only one primary winding,leading to a simplified system,less device numbers and lower cost. This converter can achieve the goal that all the power sources can supply power to the load independently or simultaneously,and energy can be fed from the load. Taking as the example,the operation principle of the boost-type bidirectional double-input full-bridge converter with single primary windiniong is analyzed. Finally,the simulation experimental results are given to verify the theoretical analysis.更多还原
