摘　　要：本文分析了逆变电源变压器中的几个特殊问题,其中包括:传递SPWM波的变压器内的磁感应强度、变压器偏磁的原因、变压器偏磁饱和时的现象以及变压器对偏磁的承受能力与变压器参数的关系,在分析这些问题的基础上,给出了逆变电源变压器的设计方法。This paper analyses several special problems in inverter transformer. It contains: the magnetic flux density of the transformer stimulated by SPWM wave, the reason of bias magnetization , the appearance of transformer saturation due to bias magnetization and the relationship between the endurance to bias magnetization and the parameters of transformer. Based on the analysis, the design method of inverter transformer is given.
