| 摘 要： | 一定强度的直流偏置会使功率铁氧化的损耗有明显增加，但是传统的铁损计算方程不能包括这种影响。本文通过在传统计算方程中增加一个损耗增量系数来实现包括直流偏置影响的功率铁氧体损耗的计算，实验测量结果表明这种方法的计算精度完全可以满足工程要求。 |
| 关 键 词： | 直流偏置 功率铁氧体 铁芯损耗 计算 |

| Abstract: | Core loss of power electronic ferrite will increase due to DC bias. The traditional calculation equation can not include influence of DC bias. This paper performs core loss calculation using a new factor added to the equation. It is verified by measurement that the accuracy is sufficient for engineering's need. |
| Keywords: | DC bias power electronic ferrite core loss |
