The openly available UltraZohm development framework eases the transition from simulation to the test bench. The framework offers the integration of automatic code generation for field-programmable gate arrays (FPGAs), either by using Simulink models based on the HDL Coder, or by synthesizing C++ code into VHDL via the Vivado high-level synthesis tool. The first use case focuses on the implementation details of an on-chip controller-in-the-loop setup, where a permanent magnet synchronous machine is emulated in the FPGA with a sampling frequency of 2 MHz. The second use case presents an efficient real-time implementation of the sphere decoding algorithm employed to solve the long-horizon finite control set model predictive control problem for a three-level neutral point clamped inverter driving an induction machine. Experimental results based on a small-scale prototype confirm that the algorithm can be executed in real time on the FPGA, with an execution time of a few tens of microseconds. Both use cases highlight the benefits of using a high-performance RCP platform for research in power electronics and their control.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89067131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The value of the switching frequency can influence the entire performance of the converter and this justifies the importance of this study. This paper is analyzing the influence of switching frequency on the reliability of the DC-DC PoL converter. This is demonstrated in terms of efficiency, thermal response, and ripple. In addition, several bench test results are shown for a switching frequency variation in a range of 50 kHz to 500 kHz, using a discrete SiMOSFET based PoL synchronous buck converter evaluation board. The switching loss in power devices, as well as the driver loss, are directly influenced by the switching frequency. The reliability calculation is based on the temperature of the device when the converter is working on a common load. A thermal scanning of the MOSFET surface is herein based on infrared photography. A modern prediction standard, like IEC-TR-62380, takes into account the concept of mission profile and it has been used to deliver information about the reliability of the converter as close as possible to reality.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89887005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proper power-electronic converters are required to drive these systems. The modular multilevel converter is the state-of-the-art solution for high-voltage applications that require a DC stage and that operate with a fixed frequency at their AC terminals. This converter topology can reach high voltage levels while operating with high power quality, high reliability and low switching frequency. The modular multilevel converter, however, presents some drawbacks such as its intolerably high submodule-capacitor voltage ripple at low frequencies and its high component count. Thus, many different converter topologies have been proposed in the literature as alternatives for high-power medium-voltage AC-AC applications, especially applications that operate at very low frequencies such as machine drives. These converter topologies present their own drawbacks and, thus, finding new converter solutions for high-power machine drives is still a topic with high research interest. In this paper, the operational characteristics and challenges of a new converter topology are presented and discussed. The proposed converter presents advantageous characteristics in comparison to other alternative topologies, indicating that it could be a suitable option to drive high-power medium-voltage electrical machines.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73334029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As consequence, it was possible to integrate these components that operate at very low currents in the miniaturized structure of electrical measuring, control or switching devices with nominal currents of tens or hundreds of amps. However, the existence of microcontrollers able of processing complex functions is outstanding in the case of the electronic trigger units integrated in automatic circuit breakers or of the arc fault detection devices.Arc fault detection devices can detect and disconnect any electric arc fault in a single-phase electrical circuit. This makes them indispensable in facilities that supply critical consumers such as hospitals, clinics, schools, etc. This paper proposes an electrical circuit that associates an AFDD with a GSM type device and an Arduino board. By programming the microcontroller from this board, it is avoided any fire having electrical causes by disconnecting the consumer from the power supply, it is started an audible alarm and the authorities of emergency situations are informed by SMS about the fault and its position.The proposed electrical circuits refer to both single-phase electrical circuits and three-phase electrical circuits.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79145981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
