However, the current stress under the DCM for two-level (2L) circuit is relatively high and there are still no linear models for the control. In this paper, T-type three-level (3L) circuit is used to construct the LCL-type grid-connected inverter (GCI). And the inverter-side inductor works under mixed conduction mode (MCM) combined by DCM when the load current is small and under trapezium conduction mode (TPCM) when it is high, so as to realize the soft switching in all switching cycles and reduce the current stress. In order to realize effective closed-loop control for the GCI under MCM, a linear charge quantity model (CQM) which takes the charge quantity output of the bridge as the control variable is proposed in this paper. Based on the proposed model, a direct charge control (DCC) method with a PID regulator working at fixed switching frequency is further proposed. Finally, the great steady-state and dynamic performance of the proposed model and control method is verified by the simulations and experiments.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126726639","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}

With the conventional $phi$-based control strategy, ICN converters are well-suited for applications with wide variation in input voltage, owing to wide range soft switching capability of their inverter transistors. The control strategies presented in this paper simultaneously allow soft switching of all its inverter and rectifier transistors, thus extending the converter’s applicability to higher and wider output voltages. Two such control strategies, namely, $psi$ and $phipsi$-based control, are presented and compared in terms of their soft switching capability and residual circulating currents in the resonant tank. It is shown that $phipsi$-based control strategy offers superior performance by substantially reducing circulating currents. A 15 V-to-2.5 V, 10- W, 400-kHz ICN converter prototype is built and tested with the proposed control strategies. $phipsi$-based control strategy achieves 5% higher efficiency compared to the $psi$-based control strategy.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115563505","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}

As a main original content, this work proposes a control law based on a new dynamic model of the SynRM including iron losses as well as the on-line estimation of the static inductances. The on-line estimation of the SynRM static inductances permits to inherently take into consideration the magnetic saturation phenomena occuring on both axes. The estimation law is obtained thanks to a Lyapunov-based analysis and thus the stability of the entire control system, including the estimation algorithm, is intrinsically guaranteed. The proposed adaptive FL control improves formerly developed non linear controllers, characterized either by disregarding the saturation phenomenon or by considering it on the basis of an apriori known model. The proposed control technique, has been tested experimentally on a suitably developed test set-up.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116108715","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 introduced inverter generates a seven-level ac output voltage with a maximum voltage-boosting gain of 1.5. Also, a simple modulation technique was proposed, where the capacitors voltages are naturally balanced by the series-parallel connection of the input voltage source. Compared with seven-level inverter topologies, the proposed topology is simpler and its control system does not requires sensors or balancing circuits to stabilize the dc-link voltages. Additionally, the dc-link voltage requirement is reduced by 33.33%, eliminating the need for an intermediate dc-boosting stage and making the introduced inverter a good candidate for applications such as photovoltaic panels and full-cells systems, both characterized by a low input voltage. The operation and performance of the proposed topology is validated through simulation and experimental results.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116194256","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 permanent magnet electrical machine (PMSM) fed with an inverter consisting of higher-order frequency harmonics results in further increases of eddy current loss. The magnetic properties of the permanent magnet (PM) with and without higher harmonic content excitation signals are of great interest. Despite the popularity of PMSMs as higher efficiency motors in today's era, there are few doubts regarding the study of the magnetic properties of PMs with the loss measurement process. This paper addresses this problem and its solutions. The purpose of this paper is to describe the PM loss measurement method at higher frequencies and higher temperature effects under ideal sinusoidal and non-sinusoidal external magnetic fields. The ideal sinusoidal external magnetic field signal for measurement is generated using a frequency generator and linear power amplifiers. In contrast, the non-sinusoidal pulse with modulated (PWM) signal is generated using an inverter.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122572006","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}

However, the volume and the losses of the high-frequency transformer are responsible for a considerable share of the total volume and losses of the converter system. Transformer-less capacitor-coupled dual active bridge converters that replace the transformer with series-connected capacitors have been introduced to mitigate this problem. For both the transformer-coupled and capacitor-coupled dual active bridge converters, digital isolators are used to transmit the high-frequency gating signals for the primary or secondary full-bridge circuit. However, the digital isolators bring in the issue of system reliability, manufacturing cost, and propagation delay. In this paper, a phase control using a network node voltage feedback for the capacitor-coupled dual active bridge has been proposed. The proposed method implements the phase-locked-loop on the opposite side phase information directly extracted from the node voltage of the capacitor-coupling network. The proposed method eliminates the digital isolator or any other communication methods for capacitor-coupled dual active bridge control. The proposed method is experimentally verified with a 2.2 kW capacitor-coupled dual active bridge DC-DC converter prototype with a peak efficiency of 98.6%.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122614085","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}

Radial directions are actively positioned, and axial and tilting directions are passively stabilized with a disk-shaped rotor. In the CP and HCP bearingless machines, the radial suspension force is generated by a two-pole suspension winding. However, the radial suspension force characteristics are considerably different in the two machines. The radial suspension force of the HCP is generated when a two-pole suspension flux is superimposed on a homopolar flux by thrust permanent magnets. In contrast, the CP bearingless motor requires $p pm 2$-pole suspension fluxes modulated by the salient-pole rotor core to generate the radial suspension force with a p-pole rotor permanent magnet flux. As a result, the force error angle of the HCP bearingless motor is significantly low compared with the CP bearingless motor. A prototype machine of the HCP bearingless motor is fabricated and tested. In the experiment, it is demonstrated that stable magnetic suspension and rotation are achieved at 1000 r/min.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122071932","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}
