A Single-Stage Bimodal Transformerless Inverter with Common-Ground and Buck-Boost Features

Round 1

Reviewer 1 Report

The authors are advised to include the following in the revised manuscript:

1. In Table 3 (comparison table), the percentage values of the stresses also need to be included in addition to the expressions.

2. Photograph of the converter and the experimental setup.

3. Details about the nature of load and the experimental setup.

The authors need to address the following queries:

1. What about the converter's dynamic response? Was the converter operated under closed-loop condition?

2. What controller and closed-loop control technique was employed?

3. What about the converter losses and loss distribution?

4. In Fig. 8a, are the voltage across the D1 and S1 correct? Both seem to be conducting always, without any turn-ON and turn-OFF duration.

5. What was the equipment (model number along with accessories) used for observing and capturing the waveforms?

Reviewer 2 Report

When the system is operated in dual mode, more elements are used than conventional dc-dc converters. Therefore, the resulting efficiency and losses should be compared with those in other studies. Why was IGBT not used but MOSFET was preferred? The response of the proposed system at low modulation index values gives similar results. Units should be given in Figure 5 and Figure 6. The numbers and text on some figures should be made more visible. What was used in the system as a controller?
