在比对集成磁件和分立磁件设计流程的基础上,提出了一套判定2个或者3个以上分立磁件可否集成的判据,对在集成磁件设计当中出现的磁通相互抵消现象,采用几何方法给出了直观的解释和合理的解决方案。分析了集成磁件复现分立磁件电流波形的可能性及条件。对于集成磁件引起的电路拓扑出现电流环路问题进行了深入讨论。在这套理论的基础上,提出采用绕组遍历法设计集成磁件的计算机方法。通过对采用倍流整流的半桥拓扑中3个分立磁件的集成设计,验证该设计方法直观、有效。
On the basis of comparing the design process of the integrated magnetic and discrete magnetic parts, a set of criteria to judge whether two or more discrete magnetic parts can be integrated is proposed, which cancels the mutual offset of magnetic flux in the design of integrated magnetic parts , The use of geometric methods gives an intuitive explanation and a reasonable solution. The possibility and conditions for the current waveform of discrete magnetic parts to be reproduced by integrated magnetic parts are analyzed. In-depth discussion is made on the current loop problem in the circuit topology caused by the integrated magnet. Based on this theory, a computer method of designing integrated magnetic parts by using winding traversal method is proposed. Through the integrated design of three discrete magnetic parts in a half-bridge topology with double current rectification, the design method is verified to be intuitive and effective.
