To the Reviewer 5:
The authors appreciate your well-advised comments. Based on your comments, highlighted texts have been added in the new version of the manuscript.
The authors didn 't mention, how the presented work is different from the existed DPWM schemes presented in the literature. The introduction should be elaborated from this prospective?
Thank you for your suggestion. These have been highlighted in the introduction section.
highlight the issues in the existing methods, pros and cons of the proposed methodology and their superiority over the existed DPWM schemes

industrial drives) three-level inverters are used extensively [1]-[2], and recently, their application in low-voltage, high-power traction applications have been introduced [3]-[5]. In these applications, the three-level inverters often need to operate with modulation indices (m) lower than 0.5 [6]- [10]. Additionally, at lower modulation indices, traction drives operating with induction motors (IMs), interior permanent magnet motors (IPMs) or synchronous reluctance motors (SynRMs) may need to provide higher reactive power, thus operating with a lower power factor (pf) [9], [11]- [17]. For example, in [9], the power factor of IPMSMs at 0.2 modulation index is shown to be 0.52. The power factor of SynRMs also varies between 0.3-0.7 based on designed saliency [17]. Hence, the three-level inverters for these applications need to be controlled appropriately at lower modulation indices and lower power factors for optimum
