Traditional grid-connected inverter employs lowfrequency output isolation transformer. It increases weight and cost.
传统的并网逆变器输出端采用工频变压器,体积重量大,成本高。

So the transformer core material is required to be the one with properties of low losses at high frequency, high dynamic permeability, high saturation induction and low remanence.
要求变压器铁芯具有低的高频损耗,高动态磁导率,高饱和磁感应强度和低的剩磁比。
