摘要
对DC/DC并联供电模块电流能按任意比例分配电路拓扑和数学模型进行了研究。设计其一DC/DC变换器模块为电压闭环自动控制系统,另一DC/DC变换器模块按电流源性质设计闭环自动控制系统。对采用这种DC/DC变换器模块的并联系统建立了动态小信号数学模型,根据建模的结果设计了补偿网络。对DC/DC并联供电模块电流分配策略进行了详细的分析,仿真和实验结果验证电路拓扑及控制策略的正确性。
The circuit topology could be distributed by the current of DC/DC power supply modules according to arbitrary percentage and its mathematical models were studied. A DC/DC voltage converter module was designed as the closed-loop control systems, and according to the property of current source, another DC/DC converter module was designed as the closed loop control systems. A dynamic small signal mathematical model was established with the parallel system of DC/DC converter modules, and the compensation network was designed based on the modeling. The current allocation strategy of DC/DC power supply modules were analyzed in detail. The simulation and experimental results verify the correctness of the circuit topology and control strategies.
