The use of a spread spectrum modulation technique can reduce the conducted common mode electromagnetic interference. However, the spectrum expansion of periodic pulse width modulation is not strong enough and is accompanied by spectral overlapping phenomenon in the high-frequency band. In addition, the chaotic pulse width modulation generates a large number of low-frequency components and the spectrum expansion is not controllable. In this paper, discrete chaotic sequences are used to modulate the modulation frequency of the periodic function for the second time to enhance the harmonic side-band extension capability of the periodic pulse width modulation, and to solve the problem of the accumulation of the low-frequency harmonic components caused by the chaotic pulse width modulation, and the introduction of the wide-band characteristics of the chaotic sequences can alleviate the overlapping phenomenon of the spectrum in the high-frequency band. Through the whale optimization algorithm, the relevant modulation parameters affecting the periodic-chaotic pulse width modulation–modulation frequency fm and frequency extension range Δf are optimized. Finally, a 500W phase-shifted full-bridge converter experimental prototype verifies that period-chaos pulse-width modulation has better common mode EMI attenuation characteristics when compared with period pulse-width modulation and chaotic pulse-width modulation. In addition, it verifies the accuracy of the optimized parameters. The modulation means and optimization methods proposed in this paper can be used to reduce the conducted electromagnetic interference in switching power supplies.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"11 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940810","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}

During heavy load and frequent lifting, power devices of the inverter will generate considerable power loss, which often leads to overheating or even damage to power devices and reduces the thermal stability of the whole system. This study proposes a quasi-deadbeat model predictive current control (QD-MPCC) strategy based on the neutral point clamped (NPC) three-level inverter. First, the QD-MPCC quasi-beat controller of the induction motor is designed, the digital delay compensation strategy is developed, and a closed-loop flux observer is adopted to improve the flux observation accuracy. Second, the traditional QD-MPCC strategy is improved. The loss model of the NPC three-level inverter applied to the explosion-proof hoist is established. Then the loss result calculated according to the predicted current is taken as the new control target, and the loss is dynamically optimized according to the operating curve. Finally, the robustness of the improved QD-MPCC strategy and its effectiveness in online power-loss management to improve the thermal stability of the system are verified by simulation and experiment.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"23 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940812","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 MRTPC consists of a four-element resonant tank (FERT), a three-element resonant tank (TERT), and an LC resonant tank (LCRT). Due to the fact that the FERT can be configured with first and third resonant frequencies (RF), it can transmit the energy of the fundamental and third harmonic components. By reasonably setting the RFs of the FERT, TERT, and LCRT, decoupling control of primary and tertiary energy transmission can be achieved. Due to the characteristics of the FERT, TERT and LCRT at different frequencies, decoupling the transmission of the power of the primary and tertiary frequency components can be achieved even when there is a certain deviation in the parameters of the resonant elements of the FERT. This feature can effectively reduce the cost of selecting resonant elements. To improve the efficiency of the MRTPC, an optimized triple-phase-shift modulation strategy (OTPSMS) is proposed to minimize the root mean square value of the resonant current (RMSRC). For the nonlinear problem of minimizing the RMSRC, the KKT condition is used for the optimization solution. Finally, an experimental prototype with a power level of 1 kW is built to verify the theoretical correctness of the MRTPC and its OTPSMS.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"32 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940925","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}

Then the power model of the starter/generator system is analyzed considering the disturbance caused by inherent parameter uncertainty and external load variation. To improve the dynamic response performance of the DC-link voltage, an integral terminal sliding-mode DC-link voltage controller (ITSMVC) with an extended state observer (ESO) is proposed. The system stability is verified by Lyapunov theory. A simple parameter design method for the proposed ESO-ITSMVC is adopted to ensure satisfactory performance. Finally, a comparison of experimental results with the conventional ITSMVC, the active-disturbance rejection controller (ADRC), and the disturbance observer-ITSMVC (DO-ITSMVC) is carried out.

The proposed AD-ZSVPWM control technique enhances the output power quality by reducing total harmonic distortion (THD) and conduction losses. Low THD is achieved by increasing the algorithm’s accuracy using a division of six vector states in each switching period and the distribution of six shoot-through states within the period. The conduction losses are reduced by splitting each sector into two subsectors of 30°. The proposed control scheme has the following advantages: reduced THD, low conduction loss, and increased boosting factor. MATLAB/Simulink software is used, and an experimental test is conducted to validate the proposed strategy. PLECS software is utilized to calculate the switching and conduction losses. For experimental verification, a hardware test bench comprising a dSPACE DS1104 board that controls a three-phase quasi Z-source inverter that supplies an R-L load is used.

To address this problem, a series arc fault detection method based on multi-domain depth feature association is proposed in this paper. By building an experimental platform, the current signal data on normal and arc fault states under different loads are obtained. The time-domain features, frequency-domain features and wavelet packet energy features of the current signal are extracted. To enhance the quality of the data, the importance of each domain characteristic is ranked using four distinct tree techniques, and the most useful features are chosen. A one-dimensional stacked neural network (1D-SNN) fault detection model is constructed to further extract the depth features of each domain. To achieve series arc defect detection, the depth features are combined and fed into a fully connected neural network. The Radam algorithm is used to optimize the detection model. It is then compared with Adam, SGD, and RMSprop optimization algorithms, which verifies that Radam has a better effect on the optimization of the arc detection model. Experimental results show that the average detection accuracy is 99.63%.","PeriodicalId":50081,"journal":{"name":"Journal of Power Electronics","volume":"26 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140941040","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}
