有研究者指出了《IEC 602052006-01磁性零件有效参数计算》中PQ型磁心对有效参数的计算公式的瑕疵并进行了修正.利用磁心功耗与最大磁通密度的关系推导出指数n与磁心Ae和P0的关系式.改变磁心B尺寸,用标准计算公式和修正公式得到对应的Ae,并测试出对应的功耗,代入n与磁心Ae和P0的关系式便可得到相应的n值,与材料的n值进行比较便可验证PQ型磁心对有效参数计算公式的正确性.结果表明,用标准计算公式计算Ae而得出的n值与材料的n值相差较大,而用修正公式计算Ae得出的n值与材料的n值相差较小,验证了PQ型磁心对有效参数修正计算公式的正确性.

Some researchers have found and modified the errors of the formula for calculating the effective parameters of PQ-core pair in “IEC 60205 Ed.3: calculation of effective parameters of magnetic piece parts”. In this paper, an expression on n, Ae and P0 was derived by using the formula on Bm and P. By changing the size B of core,and using Ae calculated from the standard formula and the modified formula, respectively, and by measuring corresponding parameter of power loss, the values of n were calculated as we substitute all these parameters into the expression on n, Ae and P0. By comparing the value of n we can conveniently verify whether the formula is right for calculating the effective parameters of PQ-core pair. The result shows that the value of n calculated by using Ae from the modified formula is close to that of material, but it differed significantly by using Ae from the standard formula in“IEC 60205 Ed.3:calculation of effective parameters of magnetic piece parts”. These results showed that the modified formula is more accurate than the standard formula in calculating effective parameters of magnetic piece parts.
