Among open-circuit faults, those in power switches of voltage source converters (VSCs) are the most common ones. Nevertheless, in other cases a poor connection or incipient faults may cause an imbalance in the value of the stator resistances. In this case the phase is not open but this anomalous situation requires detection and eventual isolation. This phenomenon is usually called resistance dissymmetry and it leads to current imbalance that in turn reduces efficiency and produces overheating. Moreover, the variation of the machine parameter is an important issue in those control methods based on the machine model, as it is the case in model predictive control (MPC). For this reason, this work presents a resistance dissymmetry detection method based on the vector space decomposition (VSD), implemented together with a MPC-based six-phase induction motor drive. Simulation results are employed to validate the goodness of the proposed method.","PeriodicalId":243099,"journal":{"name":"2017 International Symposium on Power Electronics (Ee)","volume":"23 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122334732","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}

Soft-switching condition for primary switches has been derived considering the parasitic capacitance of elements in resonant circuit. A comparison is made between characteristics of cascade GaN and state-of-the-art Si switching devices and its effect on the value of resonant current. The concept of matrix transformer has been described and applied in the design of LLC resonant converter. Area product method for selecting appropriate size of ferrite core is presented in respect to the value of the transformer magnetizing current and zero voltage turn-on condition for primary switches. As shown, additional core losses due to the use of matrix transformer structure is negligible compared to reduced conduction and switching losses. Design of 400V/24V 500W high frequency LLC converter with matrix transformers is presented, and experimental model is made in order to verify the analysis. Experimental results recorded on a LLC converter prototype are provided to verify fulfilling of the soft-switching condition for primary switches in specified switching frequency range.","PeriodicalId":243099,"journal":{"name":"2017 International Symposium on Power Electronics (Ee)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114512565","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 VIC is meant to replace large, expensive and unreliable electrolytic capacitors, and is mainly intended for applications where random fluctuations of the DC bus voltage may occur (i.e., the VIC is not tuned to one particular ripple frequerncy). Connecting a VIC into a larger circuit, such as a power supply based on a power factor compensator (PFC) is relatively complicated, because the VIC charge controller needs access to the voltage control loop of the power source (e.g., the PFC). The plug-and-play realization of the VIC, proposed in this paper, can be connected directly to the DC bus like a usual filtering capacitor, no extra connections are needed. This is achieved by automatically adjusting the reference voltage of the VIC so that it will be equal to the equilibrium voltage of the DC bus (i.e., the constant DC bus voltage at which current supply and current demand are equal). We investigate carefully the output impedance of the plug-and-play VIC. This impedance must behave like a relatively small capacitor both at very low and at very high frequencies, but must be very small (ideally, zero) at an intermediate range of frequencies (the range where the ripple is expected). For the stability of complex interconnected systems, it is recommended that the output impedance of the plug-and-play VIC should be positive-real. We discuss how to achieve these properties by very careful choice of controllers and filters. The results are tested by simulation and experiment using a 300V demo system with a 270W load.","PeriodicalId":243099,"journal":{"name":"2017 International Symposium on Power Electronics (Ee)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116443675","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 control capabilities of the VSI are very essential in transforming the passive distribution network into an active one. In this frame, the modeling, control and stability analysis of a VSI, standing as an interface between a dc current source and a three-phase voltage grid, is investigated. Adopting the mean value model of the VSI in the synchronously rotating d-q reference frame, a pair of simple cascaded mode controllers are proposed to locally regulate the reactive power and the dc voltage, respectively. As shown in the paper, stable inner-loop current controllers can be of simple proportional-integral (PI) form with damping, which are fully independent from the system parameters; the outer-loop voltage and power controllers are also of simple PI type. Hence the paper focuses on presenting the detailed nonlinear analysis needed for proving stability of the VSI with the proposed controllers incorporated. Finally, the theoretical results are further verified by extended simulations.","PeriodicalId":243099,"journal":{"name":"2017 International Symposium on Power Electronics (Ee)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129882287","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}

Shunt APF operates by firing power electronic devices of voltage source inverter (VSI) to produce the compensation currents. The VSI also generates high frequency switching ripple harmonics that distorts the source current. High order filters, such as LCL and LLCL, have been recently used with shunt APF to decrease the ripple harmonics and to couple shunt APF with the grid. Compared with LCL filter, LLCL filter has more effective attenuation performance at switching frequency because of demonstrating nearly zero impedance. As other high order filters, LLCL filter has resonance problem that leads the system to unstable condition. Passive damping or active damping method is exploited to mitigate the resonance impact and make the system stable. AD methods have more widespread applications and research due to no damping power losses. AD is fulfilled through making improvment in the control system. The objective of this paper is to point out notch filter based AD for shunt APF with output LLCL filter. The proposed system is constructed in Matlab/Simulink and the performance of the proposed system is investigated through simulation cases.","PeriodicalId":243099,"journal":{"name":"2017 International Symposium on Power Electronics (Ee)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114649264","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}
