Output Waveform Distortion Suppression Method of Asymmetric Sine Wave Inverter Based on Online Identification and Linearization of System Transmission Characteristics
Round 1
Reviewer 1 Report
The title is too vague and the introduction is not helpful. How is the waveform of fig1 related to the circuit of fig 2? Perhaps this is a specialized application where users are familiar with what is needed, but without reading the references a more general reader would have little idea what is needed. Fig 8 shows output voltage and current, but this doesn't seem to be related to the resistor of fig 2. In stage 3 the voltage is higher but the current is lower. It is said that the output freq is 1kHz for a switching freq of 20kHz so some filtering is apparent, but it is not clear what is meant by a “thumbnail” diagram. Aren't these experimental measurements? The term transmission is used throughout, but what does this mean? Normally transmission implies something at a distance, such as a line or wireless. Are we just talking about the filter transfer function or modelling the relationship between the control input and the output? This is some sort of PWM control so in fig 2 it would be helpful to show the control signals for the switches and how the control output affects these.
You talk about the system being open loop and therefore stable, but you show closed loop voltage control and talk in general terms about the stability of this. The distortion you are trying to reduce is caused by factors such as dead time, but it is not clear what the limitations of your method are. Perhaps this is clearer to someone working directly in this area, but for a less specialized reader more details are needed and some of the qualitative statements explained more fully.
Grammar good, but more clarity needed.

Reviewer 2 Report
1- The main objective of this paper is to generate a voltage signal like Fig. 1. However, the output voltage signals in Figs. 9, 10, 11, and 12 are different, why?
2- For the output voltage signals in Figs. 9, 10, 11, and 12, there is a DC component in the output voltage, right?
3- More experimental results should be added.
4- The results must be compared with reference [16] or [17].
5- Please improve the introduction section by adding more references. Suggest references are:
