During full load running of inverter, the inductive current RMS value and the peak current are two important parameters for designing the inductor of the output LC filter.

逆变器满负荷时的电感电流有效值和电流峰值是滤波电感设计的两个重要参数。

By comparing the heating effect of an unknown AC signal to that from a known DC reference, metrologists can determine the RMS AC quantity (voltage or current) in terms of the DC quantity.

为了对比一个已知直流参考的未知交流信号热效应，计量人员可以确定在一段时间内直流的交流有效值(电压或电流)。

Fret not, though, as the company assured us it'll be using tiny class-D digital amping that won't affect its current size, aiming to provide 80-100 peak RMS watts of power.
