摘要
针对功率开关关断过电压和EMI危害,本文从减小回路杂散电感出发,阐述了叠层母排在功率变换器中应用优势及数学模型。然后,基于电磁场理论,提出回路面积最小化无感母排设计原则,并进行H桥逆变器叠层母排结构设计。最后,Ansys有限元仿真结果表明了设计方法的合理性。
To the harm of power switch shut-off over-voltage and EMI, this paper introduces the advantages and mathematical model of laminated busbar applied in power converter, which can reduce circuit stray inductance. Then, based on electromagnetic field theory, design principles of a non-inductance busbar structure were proposed by minimizing loop area, and H-bridge inverter laminated bus structure was designed. Finally, the results of Ansys finite element simulation show that the rationality of design method.
