【摘要】 本文对燃料电池车用DC/DC变换器的数字化控制方法进行了研究。首先给出了单路Boost变换器的控制方法。为减小Boost变换器输出电压的纹波,本课题采用三相交错式Boost电路。然后利用Simulink对三相交错式Boost电路闭环数字化控制进行模拟仿真。最后通过试验验证控制方法和仿真结果。更多还原

【Abstract】 The research on the digital control technology of DC-DC converter has been developed in the paper.Firstly,the working principle and control method of the single Boost Converter are presented.To reduce the amplitude of the ripple of the output voltage,this paper use a three-phase interleaved Boost converter.And then the simulation of the digital closed-loop control of the three-phase interleaved Boost converter is adopted.Finally,the control methods and simulation results are verified by the experiment.更多还原
