This problem is successfully solved in multi-loop control methods by simple proportional controllers. Nevertheless, using the simple proportional controllers instead of conventional controllers, such as a proportional-resonant (PR) or a proportional-integral (PI) controller, leads to several disadvantages such as the steady state and transient errors. This paper investigates the multi-loop control scheme by proportional controllers using a reference frame transformation for single-phase UPS inverters. The proposed control method uses two nested proportional controllers in the synchronous reference frame. In fact, the steady state error of the UPS inverter in response to the ramp function changes to the steady state error in response to the step function using the reference frame transformation. Excellent tracking performance, no need to any derivative or integrator, fast dynamic response and simplicity of design and implementation are some advantages of the proposed method. The feasibility of the proposed control method is confirmed through simulations in MATLAB/SIMULINK.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133568368","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 FB-TPBC, featuring one input port, one bidirectional port and one isolated bidirectional output port. The operation principles of the proposed converter are analyzed. Moreover, the phase shift between the primary side and the corresponding secondary side switches and the duty cycle of the input bridge switches are two control freedoms in order to reach the power management between three ports while regulating the output voltage. This control scheme is called PWM+SSPS. Moreover, zero-voltage-switching (ZVS) can be obtained for the switches of both input and output bridges due to the proposed PWM+SSPS which improves power density and efficiency. Unified control scheme is helped to prepare higher reliability and better dynamic performance with the complex communication systems cancellation. In order to verify the theoretical analyses, the proposed FB-TPBC has been simulated in MATLAB/Simulink software environment and tested under various scenarios.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134501716","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}

Moreover, in real distribution power systems, asymmetrical single-phase nonlinear loads lead to unbalance in 3-phase non-sinusoidal line current. As a result, not only does appear a nonsinusoidal voltage at the point of common coupling, but also we expect to have neutral current due to asymmetry of the 3-phase current in a four wire system. On the other hand, under non-sinusoidal three-phase voltage condition, sinusoidal source current and proper power factor cannot be achieved at the same time. In this paper, an optimum control strategy for shunt active filter is designed to get an appropriate compromise between the power factor and current total harmonic distortion under unbalanced nonlinear load and non-sinusoidal voltage condition in four-wire system. This control strategy not only balances the source current, but also optimizes the performance of the system by minimizing the apparent power drawn from the line within the defined current THD limit. Also a neutral current compensation strategy is used to reduce losses, and improve the overall efficiency of the power system. To verify the effectiveness of the proposed control scheme, the Simulink/Matlab simulation results are provided for several unbalanced nonlinear loads.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116952059","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}
