The converter is a single-phase, single-stage boost-push–pull model. It consists of three key components: an interleaved boost, a push–pull, and a resonant tank circuit. The interleaved boost operates in DCM mode and serves as power factor correction. The push–pull converter includes a resonant tank on the secondary side of the transformer to achieve ZVS. The two switches control the boost and the push–pull circuits to create a single-stage converter. The converter in question provides an array of advantages, such as zero voltage switching (ZVS), an intermediate bus voltage that is independent of the load, and a low-ripple input current, all of which can be achieved without the need for additional filtering. The present article provides a comprehensive overview of the design procedure, simulation and experimental results, and separate operating modes analysis. To verify the design and simulation results, a 200-W interleaved boost push–pull converter (IBPPC) prototype is implemented. Finally, because it is crucial to maintain the voltage of the bus capacitor within an acceptable range, this study investigated the impact of load variation on the bus voltage.","PeriodicalId":56302,"journal":{"name":"IET Power Electronics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/pel2.12732","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this paper proposes an improved lightweight design method for micro unmanned aerial vehicles to carry a wireless charging system. The improved system uses an inductor–capacitor–capacitor-parallel (LCC-P) topology compensation network instead of a bilateral inductor–capacitor–capacitor (LCC) topology compensation network to achieve constant current charging (CC) and constant voltage charging (CV). Then the adaptive frequency conversion control is used to realize the automatic conversion from CC charging to CV charging during the charging process. Compared with the traditional wireless charging system based on a direct current-direct current converter (DC-DC converter) to achieve CC charging and CV charging, this improved system reduces the total weight of the receiving end of the wireless charging system based on ensuring the charging efficiency, which meets the demand of wireless charging systems carried by micro drone aircraft. The test results of the constructed physical system coincide with the simulation design results, and the total weight of the receiving end is only 8 g, which verifies the correctness and effectiveness of the improved design scheme.","PeriodicalId":56302,"journal":{"name":"IET Power Electronics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/pel2.12747","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insufficient DC voltage regulation and complicated LC network are principal drawbacks of these topologies. A new split source inverter (SSI) can solve problems with single-stage inverters. In this paper, SSI replaced the voltage source inverter (VSI) of a shunt active power filter (SAPF) which alleviates power quality (PQ) issues in power system. Furthermore, a VSI-based SAPF faces challenges to maintain consistent voltage across DC-link capacitor, exactly compensating current generation, and switching loss reduction in inverter. This study examined efficacy of two inverter-based SAPFs considering a modified synchronous reference frame approach for generating reference current; fuzzy logic controller for regulating DC-link voltage; and adaptive fuzzy hysteresis current controller for generating switching pulses. Ideal and non-ideal sources were considered when running the simulations for various load circumstances. The proposed SSI-based SAPF with an advanced control approach can eradicate source current harmonics to 0.52% and 0.45% under ideal source conditions, and 0.65% and 0.54% under non-ideal source conditions for non-linear loads. Similarly, the ripples in the DC-link voltage are also reduced to 2–3 V for the ideal case and 4–5 V for non-ideal case.","PeriodicalId":56302,"journal":{"name":"IET Power Electronics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/pel2.12746","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When operated in grid-forming voltage-control mode, because the PV power can change rapidly and widely, the PV inverter needs to track the power commands quickly and precisely. Traditionally, this goal is achieved with the estimation of PV power curve or PI-based multiple-loop feedback control, where flexibility, availability and accuracy are not satisfactory. Therefore, a CC/VC-based power tracking (CVPT) method is proposed, which only uses single-loop in control. The proposed method does not need to tune multiple loops and can respond faster, which is important for grid-forming voltage control. Furthermore, the different operating modes due to the limitation of PV maximum power are analysed, and a mode switch method is proposed. Simulation and experimental results demonstrate that the PV inverter can cope with power disturbances from both the power and grid sides and maintain the quality of grid voltage.","PeriodicalId":56302,"journal":{"name":"IET Power Electronics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/pel2.12745","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141652650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, inherent static and dynamic voltage balancing must be achieved. Voltage imbalance is caused by the device parameters spread, whose impact is pronounced in low-inductive circuit layouts.

It has been shown that a larger parameter mismatch will lead to uneven switching energy losses and larger voltage imbalances. It was also experimentally shown that increasing the gate resistor to slow down the devices will not always improve balancing when their parameter spread is large.

Two sets of coupled inductors (CI) and a transformer are utilized on the low-voltage side to increase voltage gain. Through the series connection of the secondary windings of the CIs with the primary windings of the transformer, the concluded voltage gain is improved by the multiplication of the turns ratios of CI and transformer. As a result, the voltage gains as well as the voltage stresses in both directions can be flexibly improved through three degrees of freedom, which are the turns ratios of the CIs, transformer and duty cycle. Clamp capacitors accomplish active clamping, and the energy saved within the leakage inductance is recycled. Additionally, some switches are performed with soft-switching and partially diminished switching losses. The steady-state analysis and extensive performance comparison of the proposed converter prove that the proposed converter outperforms the similar previous converters in the state-of-the-art. An 800 W 48 V/380 V prototype is developed to prove the performance of the proposed converter. The peak efficiency amounts of the proposed system in the high step-down and high step-up modes are 95.8% and 96.2%, respectively.","PeriodicalId":56302,"journal":{"name":"IET Power Electronics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/pel2.12725","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141674041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
