摘要: 传统双重移相控制下的双向DC/DC变换器会产生较大的回流功率，尤其当电压转换比不匹配时，会导致较高的功率损耗并降低系统传输效率。本文针对这一问题，提出一种优化的移相控制策略来控制变换器在最小回流功率点运行。在不同传输功率的情况下，采用分段优化算法计算出最小回流功率下的移相比组合，并通过实验验证了控制策略的有效性和理论分析的准确性。
Abstract: The traditional bi-directional DC/DC converter with dual-phase shift control can produce large backflow power, especially when the voltage conversion ratio is mismatched, which will lead to high power loss and reduce system transmission efficiency. To solve this problem, this paper proposes an optimized phase-shifting control strategy to control the operation of the converter at the minimum reflux power point. In the case of different transmission power, the piecewise optimization algo-rithm is used to calculate the shift comparison combination under the minimum reflux power. The effectiveness of the control strategy and the accuracy of the theoretical analysis are verified by ex-periments.
