Specifically, within the realm of MMC, the Cascaded H-Bridge (CHB) configuration has become the preferred choice for STATCOM applications. Multicarrier based PWM switching patterns are commonly utilized to control Cascaded H-Bridge (CHB) inverters. The main contribution of this paper is to comprehensively investigate the effect of multicarrier based novel modified sine modified amplitude PWM methods on the harmonic content of the Modular Multilevel Cascaded Inverter (MMCI). In order to achieve this, the MMCI circuit output voltage have been taken into account. In this work, various PWM modulations such as fixed switching frequency using fixed amplitude and modified amplitude PWM and the combination of CFD concepts using mutable amplitude PWM have been studied through both simulation and implementation of an experimental setup using dSPACE/RTI and tested with MMCI circuit. By extracting the frequency spectrum and calculation of various performance indices such as THD, DF, HLF, a quantitative comparative study of various proposed PWM techniques has been carried out. According to the results, FSF-MSMA strategy enhances the fundamental output voltage particularly at lower modulation index ranges while keeping the lower harmonic distortion of the output voltage, without involving changes in device switching losses. FSF-MSMA methods using MSMAPOD PWM and MSMAAPOD PWM, have a higher fundamental component among the chosen methods. The proposed FSF-MSMA methods using MSMAPD PWM and FSF-CFD methods using MSMACO-1 PWM switching strategy offer superior preferences including lower voltage distortion (better spectral quality) at a given range. modular multilevel converters inverters bridge circuits switches harmonic analysis switching frequency pulse width modulation modulation modified sine modified amplitude carrier power quality waveform distortion factor waveform harmonics loss factor Full Text Additional Declarations No competing interests reported.

applications and large Static Synchronous Compensator (STATCOM), industrial drive applications due to its modularity, fault tolerance and high efficiency. Specifically, within the realm of MMC, the Cascaded H-Bridge (CHB) configuration has become the preferred choice for STATCOM applications. Multicarrier based PWM switching patterns are commonly utilized to control Cascaded H-Bridge (CHB) inverters. The main contribution of this paper is to comprehensively investigate the effect of multicarrier based novel modified sine modified amplitude PWM methods on the harmonic content of the Modular Multilevel Cascaded Inverter (MMCI). In order to achieve this, the MMCI circuit output voltage have been taken into account. In this work, various PWM modulations such as fixed switching frequency using fixed amplitude and modified amplitude PWM and the combination of CFD concepts using mutable amplitude PWM have been studied through both simulation and implementation of an experimental setup using dSPACE/RTI and tested with MMCI circuit. By extracting the frequency spectrum and calculation of various performance indices such as THD, DF, HLF, a quantitative comparative study of various proposed PWM techniques has been carried out. According to the results, FSF-MSMA strategy enhances the fundamental output voltage particularly at lower modulation index ranges while keeping the lower harmonic distortion of the output voltage, without involving changes in device switching losses. FSF-MSMA methods using MSMAPOD PWM and MSMAAPOD PWM, have a higher fundamental component among the chosen methods. The proposed FSF-MSMA methods using MSMAPD PWM and FSF-CFD methods using MSMACO-1 PWM switching strategy offer superior preferences including lower voltage distortion (better spectral quality) at a given range.\u003c/p\u003e","manuscriptTitle":"A Comparative Study on Power Quality Analysis in Multicarrier based Modified Sine Modified Amplitude PWM Switching Techniques for Modular Multilevel Cascaded Inverter","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-16 13:57:38","doi":"10.21203/rs.3.rs-7302483/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-10-22T05:23:29+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-20T10:29:02+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-12T09:35:42+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-10T11:15:52+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"285242524245710071146363212588207248518","date":"2025-10-03T16:24:56+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"5256751281637014173617832301372506704","date":"2025-10-03T15:13:09+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"139793150899906582205072580995526584658","date":"2025-10-03T14:36:18+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-10-03T14:18:40+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2025-09-22T16:03:20+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-09-22T16:01:54+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-09-18T15:41:33+00:00","index":"","fulltext":""},{"type":"submitted","content":"Discover Vehicles","date":"2025-09-18T15:07:47+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"discover-vehicles","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"","sideBox":"Learn more about [Discover Vehicles](https://link.springer.com/journal/44465)","snPcode":"44465","submissionUrl":"https://submission.springernature.com/new-submission/44465/3","title":"Discover Vehicles","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"Discover Series","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"e850531a-ab6d-414f-a4c7-8f778c4bac8f","owner":[],"postedDate":"October 16th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2025-11-17T10:24:04+00:00","versionOfRecord":[],"versionCreatedAt":"2025-10-16 13:57:38","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7302483","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7302483","identity":"rs-7302483","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
