To overcome this drawback, this paper proposes a simplified modeling methodology and a control strategy for differential dc-dc converters operating as step-up converters. The proposed modeling is based on the use of the transfer functions related to the basic converters to derive the transfer functions of the differential converter. A control strategy which employs two loops is proposed to regulate the partial and the total output voltages for the differential converter. The modeling approach herein proposed is validated in the time and frequency domains. Experimental results of the differential converters operating in closed-loop are evaluated considering both the basic converters are driven by duty cycles either equal or different and assuming their respective triangular carries are shifted by 0° or 180°.","PeriodicalId":442384,"journal":{"name":"2021 Brazilian Power Electronics Conference (COBEP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129162567","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 simulator solver is based on the Modified Augmented Nodal Analysis (MANA), which allows solving different circuit topologies, including circuits with ideal switches. Moreover, for real-time applications like hardware-in-the-loop, these equations must be calculated in a tiny execution time, essentially smaller than the simulation time-step. Because of this constraint, the simulator is often implemented in a dedicated platform. This work employed a Field-Programmable Gate Array (FPGA) device, which due to its intrinsic parallel nature, allows the time-step to be reduced to achieve the real-time constraint necessary for the real-time simulation of power converters, once this type of system requires very small time-steps. For validation purposes, it is assembled a hardware-in-the-loop implementation of a DC/DC boost converter and a three-phase inverter, composing a system with diverse applications in photovoltaic panels and renewable energies. The implemented simulator works as intended and can simulate a power electronic converter with a simulation time-step of some hundreds of nanoseconds.","PeriodicalId":442384,"journal":{"name":"2021 Brazilian Power Electronics Conference (COBEP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128655227","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}

Even in scenarios with a high penetration of power electronics devices and nonlinear, distorting loads, the voltage quality must be ensured via an efficient control strategy. Furthermore, stability assessment of such a system is quite important inasmuch as the overall stability depends both on the inverter impedance and on the time-variant equivalent impedance of the load. This paper describes a dead-beat controller design procedure for voltage-source inverters with LC output filter. A harmonic-stability analysis via the impedance-based criteria is presented taking into account the existence of unstable poles in the impedance ratio. The pseudo-random binary sequence technique and the cross-correlation method are employed to identify the impedances associated with the system stability.","PeriodicalId":442384,"journal":{"name":"2021 Brazilian Power Electronics Conference (COBEP)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121188381","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}
