Abstract

Energy management strategy is gaining much popularity due to the involvement of conventional/non-conventional power sources with an efficient energy storing solution to offer un-interruptible power demand. Thus, in this work a simpler logic control circuit based nonisolated bi-directional DC-DC converter with both battery and super capacitor topology is proposed. For the proposed topology, first its mathematical modelling in ideal-case with parasitic in every mode of actions is presented. To control the bidirectional DC-DC converter topology, its small signal model for individual buck and boost operation is obtained by using averaging and linearization technique. Then, a unified logic circuit-based controller is designed for the obtained systems to analyze the performance of the converter in the buck and boost mode operation. The performance of the proposed topology is verified through MATLAB/Simulink environment.

具有适用于EV/HEV的能量管理拓扑的非隔离半桥双向DC-DC转换器的建模和控制

能源管理策略越来越受欢迎，因为传统/非常规电源与有效的能源存储解决方案的参与，以提供不间断的电力需求。因此，在这项工作中，提出了一种更简单的基于电池和超级电容器拓扑的非隔离双向DC-DC变换器的逻辑控制电路。对于所提出的拓扑结构，首先给出了在每个动作模式都有寄生的理想情况下的数学模型。为了控制双向DC-DC变换器的拓扑结构，采用平均化和线性化技术，得到了其降压和升压操作的小信号模型。然后，对得到的系统设计了基于统一逻辑电路的控制器，分析了变换器在降压和升压模式下的工作性能。通过MATLAB/Simulink环境对所提拓扑的性能进行了验证。
