I try to regulate in a single phase inverter with different loads, so I get the result that attached, but my question is there any way by changing a PWM technique or by using another method to get pure current signal or can reduce or eliminate the DC component from it..... With great thanks

Hi,

To get a pure sinusoidal signal I would use an averaged value converter. You can look at the averaged value converter blocks in Simscape Electrical:

Some examples using the averaged value converters:

I hope this helps.
