Most of these sources and loads are coupled by power electronic converters to the main grid. In the low voltage distribution grid level, single-phase or three-phase devices with a neutral connection can lead to harmonics at zero sequence component. Compensation of the zero sequence component requires a grid regulator with a neutral line connection and a suitable control methodology. Consequently, a power electronic inverter with split dc-link capacitors with a neutral connection is considered in this paper. The device is modelled in the symmetrical component (SC) domain and differentiated to each individual harmonic order. The transformation from the time to frequency domain is based on the heterodyne dq-transformation and the SC domain. This results in a decoupling of the control parts in terms of harmonic frequency and the sequence components (positive, negative, zero sequence). Moreover, the coupling of dq-components of the system is compensated by individual resistance to reactance ratios (R/X) decoupling terms. The validation in simulation and a real hardware test shows the strength of the control approach.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124023233","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 faster evaluation of the power losses can significantly reduce the required design time. The presented model is using modern SiC semiconductors which have significant advantages in comparison to the IGBT transistors. The model of the $3times 5$ converter is presented together with power losses analysis in different parts of the converter eg. the power circuit, input filter, and so on.

The component manufacturers implement the double pulse test with a dedicated test setup with favorable layout for minimizing the switching loop inductance. Such layout and minimized loop inductances may not be implemented with different inverter topologies. Therefore, independent tests must be done for each switch of the phase-leg to ensure the switching behavior for each possible commutation loop. This procedure becomes more critical with more complex phase-leg structures of multilevel inverters. This paper presents a double pulse testing method dedicated for a phase-leg of a three-level neutral point clamped inverter. With the proposed method, all of the commutation loops within the phase-leg can be tested at nominal voltage rating with half of the nominal DC link voltage as input. The method is verified with experimental results using a phase-leg of a medium voltage three-level neutral point clamped inverter using 4.5 kV rated insulated-gate bipolar transistors.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134193789","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}

Due to the greater number of phases, they provide better properties. Research in this area is moving forward rapidly. There are already many studies that compare the properties of conventional three-phase induction machines with multiphase machines. One of the most frequently compared features is the fault tolerance of the engine. We know that multiphase motors provide more degrees of freedom that can be used to make the motor more fault tolerant. A safety operation of the motor is one of the most important topics in the field today. This is due to the massive introduction of electric vehicles.

In this paper an approach for stability of power systems for More Electric Aircraft using the Middlebrook criterion and the eigenvalue method is applied to assess the small-signal stability.

The amazingly high efficiencies of 97 to 98%, in some cases up to 99% are achieved by zero-voltage switching techniques that allows the use of Superjunction MOSFETs with small channel resistances but relatively large parasitic capacitances. However, if the converter is to be operated in wider voltage gain range, operation at the lower end of this range can result in a huge switching frequency which would degrade the good efficiency. The idea presented in this paper is to make use of inductors with a resonance of the magnetic field. As a result, the switching frequency would have to be varied only in a smaller range. The idea is particularly aimed at future designs with switching frequencies approaching the MHz range as it will occur with GaN transistors very soon. In this frequency range, the wavelength within the magnetic material is only in the dimension of some millimeters so that the core geometry could be designed for certain resonance effects that would reduce the peak switching frequency considerably. However, this favourable effect could be impaired by other side effects such as increased losses, so the situation should be clarified by detailed experiments in the near future.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114574082","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 injection frequency for reduction of 6f-radial force harmonics in the proposed method is half of that for conventional dq-harmonic current injection. Thus, the control of current injection can be easier. Furthermore, the proposed system with a three-phase four-wire inverter enables providing the zero-sequence current without additional power electronics circuit. To demonstrate the effectiveness of the proposed method, three-dimensional FEM analysis was performed using an IPM motor with 8-pole/48slots distributed winding. The analysis results indicated that the 6f radial force harmonics and sound pressure were reduced by injection of the zero-sequence third-harmonic current while the torque ripple is largely not changed.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124675885","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}

This paper presents a phase-shift modulation (PSM) method suited for bidirectional operation of HFLC. The proposed modulation can be used for both rectifier and inverter operating modes, with control over the power factor. Zero voltage switching (ZVS) of the dc-side switches and zero current switching (ZCS) of the ac-side switches is achieved in all operating conditions. Furthermore, two switches operate at line frequency, eliminating their switching loss.
