By changing frequency, using an intermediate-frequencytransformer instead of a low-frequencytransformer can make the arc starter small, light and reliable.
利用变频方法，以中频变压器取代低频变压器，从而使引弧器具有体积小、重量轻和引弧可靠的特点。

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.
