The algorithm is adaptable to the number of harmonics for increased solution accuracy, and feeds forward optimal results for increased speed. The article then applies this algorithm to two- and three-variable modulation strategies and reproduces EPS and TPS, proving an effective new way to numerically calculate these existing modulation strategies. The frequency-domain and multi-harmonic description of the problem enables clear and precise conclusions on the nature of RMS-optimal modulation strategies. Notably, one of these conclusions is the presence of an unavoidable zero current switching boundary that exists in the operational domain and separates zones of ZVS and ZCS operation. This boundary is then analytically derived for use in control strategies. As commutation at zero or non-negative currents can introduce significant switching losses, knowledge of this boundary is crucial for Dual Active Bridge converter design. The article terminates by experimentally studying the behavior of the EPS and TPS modulation strategies in the vicinity of this boundary. Both the analytical and experimental results show that EPS, despite its higher RMS current relative to TPS, is more efficient at low powers due to its reduction of PZVS operation.</div></div>","PeriodicalId":74483,"journal":{"name":"Power electronic devices and components","volume":"12 ","pages":"Article 100130"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145465532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach leverages the inherent Degree of Freedom (DoF) offered by the common-mode (CM) voltage <em>u</em><sub>cm</sub> in three-phase systems. By systematically adjusting the CM voltage, the power distribution among all sub-modules (SM) is influenced to reduce the total losses of the Dual Active Bridges (DAB) without imposing additional constraints on the SST operation. An analytical loss model, with the CM voltage as the DoF, is derived from measured loss characteristics of an individual DAB module and extrapolated to the full three-phase SST. The proposed optimization method is implemented on a field-programmable gate array which is able to find the global loss minimum in real time. A 45 kW, 400 V<sub>AC</sub> to 750 V<sub>DC</sub> SST test bench is used to validate the methodology. The calculated and measured results over the whole power range of the prototype align which confirms the accuracy of the loss model. An overall loss reduction of up to 20% is achieved without sacrificing output voltage quality or requiring changes to the modulation scheme.</div></div>","PeriodicalId":74483,"journal":{"name":"Power electronic devices and components","volume":"12 ","pages":"Article 100125"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145361396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
