As the mandated emission limits of vehicles are expected to become stricter, advanced design methods are necessary to calculate accurate losses of machine and inverter. The approach contains the influence of inverter effects with acceptable calculation time by using a weak coupling of the drivetrain components.

LCL-filter creates several resonances in the converter dynamics which shall be damped for ensuring robust performance of the converter. The resonant behavior introduced by the LCL-filter can be attenuated with active damping (AD) instead of passive damping to improve the conversion efficiency. The active damping affects the output impedance of the converter, and the impedance should be accurately predicted in order to allow analyzing impedance-based stability of power electronics-based power systems. This paper presents the small-signal model for inverter-current-feedback (ICF) converter using only the inverter-side inductor current feedback for both control and active damping. Additionally, the output impedance properties are comprehensively analyzed. Experimental measurements from 3-kW prototype are presented to verify the analysis.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126180987","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}

A comparative analysis based on current capability and its dependency with the frequency in voltage source converters is introduced for the considered HPSD technologies.

It is suggested to use DC link capacitors for this task. This requires 5 W, 50 J and a capacitor size of about 200 cm3 per installed kW, corresponding to the size of single phase DC link capacitors. It is shown that the additional power ripple (and thus current ripple) is in the order of 0.1% and the voltage ripple of the intermediate voltage will typically remain between +/-3.6%. The related control can be easily extended by adding a voltage signal to the control voltage, which is proportional to the frequency deviation. Then, the existing controller inherently sets the required additional power fluctuation required for the virtual inertia function.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125559299","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}

Metrological characteristics are performed at standardized instruments made by Brockhaus, i.e., Epstein frames and ring coil testing module. The final application is a transformer core used in a galvanically isolated phase-shifted dc-dc converter. The efficiency of a dual-active-bridge (DAB3) DC-DC converter is influenced, among others, by the iron losses of the medium frequency transformer. The iron losses of grain-oriented SiFe, non-oriented SiFe and nanocrystalline materials are measured at medium frequencies up to several kilohertz under sinusoidal excitation. The IEM-5-Parameter iron loss formula, which is based on semi-physical parameters, is used to evaluate the material characteristics. In addition, the excitation signal is adapted to the DAB3 application. The signal is examined by using a fast Fourier transform. The semi-physical iron loss separation model is adapted to consider the occurring harmonics in polarization.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126972835","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}

Two distinct insulation concepts for the coupled coil design have been designed and passed partial discharge tests.

A model based approach can be used for validating the thermal design of those systems in any suitable modular configuration. This contribution is focused on an equivalent lumped thermal network model for a modular inverter system on a given heat sink concept. The proposed network representation is based on spatial splitting of the heat sink geometry whereby the lumped network elements are parametrized by means of the heat sink geometry. Since the proposed network is easy and straightforward, a minimum of variables are introduced to adjust the temperature results empirically with FEM results on certain reference operation points. Furthermore, modularity is considered due to the coolant and therefore, customer specific placement of modules can be investigated. Finally, the proposed model is compared with FEM results of a worst case system configuration, the influence of the introduced adjustment variables is shown and further validation results with thermal measurements and FEM results of different system configurations are given.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122310469","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}
