This paper proposes an improved Particle Swarm Optimization (PSO) strategy for Fractional-Order PID (FOPID) control with limited parameter selection, aiming to address the poor performance of inverter modules in arc plasma power supply systems. The proposed strategy incorporates the spiral position updating mode from the Whale Optimization Algorithm into the position updating process of PSO, which improves particle diversity, global search capability and optimization stability. The effectiveness of the proposed method is verified by comparing it with the Ziegler–Nichols tuning method and the standard PSO algorithm in the MATLAB/Simulink simulation environment. A model of an inverter system is established for validation purposes. The results indicate that applying the improved PSO-based FOPID control strategy to the inverter process of the arc plasma power supply system significantly enhances the output waveform quality, reduces harmonic distortion, and achieves excellent control performance.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"165 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A peripheral circuit was proposed to dynamically control the independent back-gate electrode of the DSOI, with a zero bias for the ON-state and a negative bias for the OFF-state. A heavily doped drift region was designed to maintain a low specific on-resistance (Ron,sp), where a negative back-gate bias would induce positive charges to compensate for the heavily doped ionized acceptors. This results in an improved breakdown voltage (BV). Therefore, it rebuilds the traditional reduced surface field (RESURF) condition.

To solve the problem caused by the increasing number of functions of new capsule robots and the fact that the traditional three-dimensional receiving coil occupies excessive inner space, a two-dimensional square transmitting coil with an embedded ferrite core is proposed. The proposed transmitting coil consists of two pairs of rectangular solenoid coils distributed radially along the human body. By changing the direction of the current flow, it can generate a two-dimensional magnetic field covering the whole central plane. This paper presents a theoretical model and conducts finite element simulations to analyze the magnetic flux density in the center plane. To evaluate the effectiveness of the proposed system, two prototypes of transmitting coils with and without ferrite cores are created, tested and compared to assess the performance improvements. Results indicate that the transmitting coil with a ferrite core increases the power transfer efficiency from 5.07% to 6.11%. In addition, attitude experiments reveal that the receiving coil efficiently captures sufficient energy at various angles when operated in the center plane.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"64 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141867969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the discontinuous modulation strategy can effectively reduce the switching losses of power devices. When the discontinuous modulation strategy is used in Z-source inverters, the switching sequences and the shoot-through states need to be arranged reasonably. This paper provides a method for comparing the switching losses of different modulation strategies by calculating the current that is passed through a switching device for a fundamental cycle. The calculations show that the Z-source inverter switching losses are determined by the number of switching actions in a switching period and by the method of insertion of the shoot-through state. Based on this, a generalized discontinuous modulation strategy for Z-source inverters is proposed. This modulation strategy achieves optimal switching losses when the power factor is less than 1. The method of redistributing the shoot-through states can be applied to other modulation strategies to achieve loss optimization. The effectiveness of the proposed modulation method is demonstrated by MATLAB/Simulink combined with PLECS simulation. Finally, and a low-power platform is built for experimental verification.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"21 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141780059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equivalent series resistance (ESR) of each energy component is considered to achieve a more precise model. The model, which is modification of the conventional averaging equation, accurately reflects both the remaining current and the actual charge on each capacitor in DCM. The proposed model utilizes a new duty ratio constraint and predicts better than previous models at high frequencies. The dependent sources of the switch components are derived from the modified averaged equation, and an implementation of the model in LTspice XVII is provided to facilitate the frequency response analysis. The frequency response of a prototype SEPIC in DCM, with an input voltage of 5 V, an output voltage of 13.5 V, and a switching frequency of 100 kHz, was experimentally measured to verify the proposed model. Simulation and experimental results demonstrate that the proposed averaged switch model solves the discrepancies at high frequencies, which was a limitation of previous models.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"6 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
