To address these aspects, Optimized Pulse Patterns (OPPs) can be integrated into the modulation strategy. This research investigates the effects of OPPs on the current distortion of salient permanent magnet synchronous motors (PMSMs) applying different symmetry conditions. It places a particular emphasis on three-pulse switching within the overmodulation region. A mathematical model of salient PMSMs is used to demonstrate that the voltage phase angle significantly influences current harmonics. It is revealed that even with a low number of pulses, satisfactory sinusoidal currents can be achieved at high voltage phase angles, thereby reducing the inverter's switching efforts while preserving current waveform quality. Different waveforms such as quarter- and half-wave symmetry (QWS), unrestricted half-wave symmetry (HWS) and restricted HWS are compared, with an innovative approach proposed for unrestricted HWS. The benefits and drawbacks of these waveforms in application to salient PMSMs are investigated, with emphasis on the overmodulation region. It is noted that HWS shows benefits over QWS at medium-load operating points and when zero-vectors are in the waveforms. In contrast, no significant advantages of HWS over QWS could be identified in the overmodulation region. The research proposes a practical OPP implementation strategy that balances effort and efficiency based on this knowledge. Unlike previous studies that used random initial angles to explore solutions, this study methodically examines the solution space for HWS and QWS, selecting initial angles that enhance the chances of finding the global optimum.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1280-1296"},"PeriodicalIF":5.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10660503","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142169612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the challenge lies in achieving rapid and robust synchronization with the faulted grid while effectively limiting the fault current. To address this, this article proposes a direct current-synchronization control (DCSC) scheme in the converter synchronous reference frame, which directly regulates the VSC current for synchronization. The validity of DCSC is substantiated by analyzing the relationship between the VSC current and phase angle, where power serves as an intermediate variable. The analytical solution for the steady-state stability boundary of the DCSC-based VSC-grid system under fault conditions is derived, which demonstrates the enhanced synchronization stability of DCSC compared to the conventional power-balance-based synchronization (PBBS) after large grid disturbances. The stability boundary of DCSC under fault conditions exhibits a voltage-magnitude-independent characteristic, resulting in a wider power angle boundary. Furthermore, this stability boundary can be translated to determine the stable operating range of the power reference ratio so that a consistently stable DCSC-based VSC-grid system can be assured under fault conditions. To increase the dynamic synchronization speed after faults, a control gain self-adaptability (CGSA) approach is introduced into the DCSC scheme. The experimental results validate the theoretical findings, affirming the effectiveness of the proposed control scheme.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1484-1499"},"PeriodicalIF":5.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10652590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proportional-integral (PI) control UPQC-DG systems are crucial for maintaining power quality by stabilizing the DC link voltage, which is also essential for the seamless integration of distributed generation into the power grid. Effective PI control ensures minimal voltage fluctuations and rapid response to disturbances, thereby enhancing overall system reliability and efficiency. However, traditional PI tuning methods, like the Ziegler-Nichols (ZN) approach, often fail to provide optimal performance under dynamic conditions in such complex converters. To address these limitations, this paper presents an innovative approach for real-time tuning of PI controllers in UPQC-DG systems using Particle Swarm Optimization (PSO). The primary objective is to dynamically optimize the PI controller parameters to enhance the stability and performance of the DC link voltage under varying operational conditions. The proposed method was validated in a real-time simulation environment using the OPAL-RT 4512 platform. The results demonstrate the PSO-based method's superior ability to reduce steady-state errors and enhance dynamic response as well. This study underscores the potential of PSO for real-time adaptive control, providing a robust solution for maintaining high power quality in UPQC-DG systems and improving the stability and reliability of distributed generation systems.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1419-1431"},"PeriodicalIF":5.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10643265","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, coupling pads have nonlinear characteristics that depend on various factors, such as the number of coil turns, the diameter, the permeability of the magnetic material, and the amount of aluminum. Therefore, verifying the operation is necessary when applying various position and control algorithms after configuring an IPT system. The input/output characteristics of the IPT system are mainly determined by the coupling pad and the employed compensation topology. Verifying the operation of the coupling pad becomes challenging when the IPT application's required input/output characteristics exceed the experimental voltage range in laboratory environments. The same electrical stress is applied to the coupling pad through topology reconfiguration and resonance component tuning, and the input/output characteristics can be flexibly changed to present a guideline that can be tested in a laboratory environment.
