| 摘 要： | 采用传统陶瓷工艺,制备了功率MnZn铁氧体材料。根据磁滞损耗、涡流损耗和剩余损耗与频率的关系,在Bm为50mT和200mT两种典型工作磁通密度下,对JPP—44、JPP—5两种典型低损耗MnZn铁氧体材料进行了损耗分离。结果表明:JPP—5材料的涡流损耗,最低可为JPP—44材料的1/10,而其磁滞损耗相当于甚至超过JPP—44材料,并深入分析了它们损耗组成不同的原因。 |
| 关 键 词： | 无机非金属材料 MnZn铁氧体 功率损耗 损耗分离 |

| Abstract: | MnZn ferrites for power supplies were prepared by conventional ceramic processing techniques . The hysteresis loss, eddy current loss and residual loss were separated from the total power loss of two types power loss MnZn ferrites JPP-44 and JPP-5 by extrapolating the PL/f-fplots. The power loss composition of JPP-44 material with low loss at middle frequency is very different from that of JPP-5 material with low loss at higher frequency. And the reason of the difference was also lucubrated. |
| Keywords: | non-metallic inorganic material manganese zinc ferrites power loss loss separation |
