Thermal analysis of heat sinks can be a complex problem as it involves different heat transfer mechanisms, and it is often necessary to use finite element simulations to obtain accurate results. However, these simulations, being very slow, are relegated to the validation process. This paper proposes a thermal model of heat sinks based on artificial neural networks. The model, unlike previous state-of-the-art models that only obtain the average temperature of the heat sink, is able to obtain a thermal map of the heat sink surface, as if it were an image, by using convolutional layers. The main advantage of this approach is that using these convolutional layers, the model is able to efficiently process how the elements are distributed on the heat sink. This model, valid for heat sinks of very different sizes in both laminar and turbulent flow, has an error of less than 1.5% and is 1500 times faster than finite element simulations, so it can be easily used in brute-force optimization processes, where many different designs need to be analyzed.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1500-1509"},"PeriodicalIF":5.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10696942","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142447193","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}

However, one of the concerns in a DC microgrid is proposing and implementing a new algorithm due to safety concerns and system stability. Properly coordinating a DC microgrid is one of these challenges. Moreover, protecting the system from unpredictable transient overshoot plays a significant role in system stability and SSCB performance. Consequently, the design of a virtual test platform for monitoring the system's behavior in challenging situations holds significant importance. To address these matters, this paper presents an examination of a DC microgrid using a novel, easy-to-implement, and cost-effective controller hardware-in-the-loop (CHIL) test platform. This platform utilizes MATLAB/Simulink software as a simulator and proposes a new communication path between the simulator and real-world controllers. Additionally, a new method to control the system in overshoot situations is proposed. To demonstrate the effectiveness of the proposed CHIL platform, three short-circuit CHIL tests are performed for load#1 to load#3 at 430 A, 300 A, and 180 A fault currents, respectively. To investigate the designed algorithm protection, a complex protection experiment was conducted to evaluate the performance of the designed algorithm under multiple transient overshoot conditions in the current.

To ensure sustained and reliable operation, dc MGs are commonly linked to utility grids through interlinking converters. However, with the increasing adoption of small-scale dc MGs for residential and commercial applications, the traditional approach of using a dedicated converter for each MG can significantly increase system size and cost. This paper proposes a single-stage non-isolated multiport converter (MPC) to interface the three-phase ac grid with 400 V dc MGs. The MPC enables direct power sharing between dc MGs, minimizes the dependence on the ac grid, and enhances the efficiency and power density of the power electronic interface compared to using multiple two-port converters. The motivations for the proposed converter include its single-stage power conversion among different ports, potentially leading to enhanced efficiency and power density. Furthermore, the absence of bulky intermediate dc-link capacitors and transformers in the proposed topology contributes to improved power density and reduced costs. Although designed for 400 V dc MGs in this study, the proposed MPC boasts buck-boost capability and bidirectional power flow at all ports, independent of the dc ports' voltage, providing the flexibility to directly interface with a wide range of dc systems. The performance of the converter is assessed through experimental tests under various operating conditions.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1432-1445"},"PeriodicalIF":5.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10681266","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250137","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}

With the emergence of wide-band-gap (WBG) devices, the tendency has grown towards using high switching frequencies to improve converters’ output power quality and minimize switching harmonic filters footprint. While high-frequency switching finds significant success in low and medium-power applications, it is not the best practice to reduce the filter size when applied to medium voltage (MV) high power (HP) inverters implemented with high voltage levels. In this paper, we show that the least filtering requirements for MV HP higher level inverters is achieved using the modulation strategy with the least switching, i.e., the staircase modulation. The paper compares the harmonic filter requirements and power losses for low-frequency and high-frequency pulse-width-modulated MLI. The analysis shows that low-frequency switching not only achieves the lowest losses, but also produces the lowest line-to-line voltage total harmonic distortion (THD), which allows eliminating both voltage and current harmonic filters in higher level inverters.

This pattern results in thermal cycles on the devices resulting in mechanical fatigue that leads to gradual deterioration of the power electronic components. Consequently, evaluating the power electronic converters reliability is critical to facilitating fast EV charging. This paper focuses on the reliability analysis of the phase-shifted full-bridge DC/DC converter within EV fast chargers, with a specific emphasis on the battery charging profile.

This is achieved by using a numerical approximation that only slightly reduces the solution accuracy.
