摘　　要：在新能源工业中双向DC/DC变换器的作用举足轻重。基于两相交错并联BOOST拓扑,分别从目标电压跟随、电流纹波、响应速度等角度,采用传统PI控制器与模型预测控制算法相结合的方法,对BOOST模式下DC/DC变换器输出电压超调量与稳态误差、系统调节时间等方面的性能展开研究。实验结果充分验证了设计方案的可行性和有效性。The role of bi-directional DC/DC converters in the new energy industry is important. Around the two-phase interleaved parallel BOOST topology, the combination of traditional PI controller and model predictive control algorithm is used to control DC/DC converter in BOOST mode from the perspective of target voltage following, current ripple and response speed, the performance of output voltage overshoot and steady state error, system adjustment time and so on are studied. The experimental results fully verify the feasibility and effectiveness of the design.
