Besides the undoubtable advantages as high capacity per volume and low price per capacity unit, they are relatively low reliability and limited lifetime. This paper describes the aging mechanisms, change of parameters over time and process of artificial ageing of electrolytic capacitors. The accelerated aging of these elements helps to discover the boundaries of ESR growth and degradation of capacitance in comparison to initial values, how changes the bode diagram of impedance over aging. The obtained data is useful for development of diagnostic algorithms for power converters, design considerations for high reliability designs and better understanding of lifetime estimation of electronic devices. The paper contains the data obtained from real tests made with electrolytic capacitors of small values as an example. Capacitor accelerated ageing is made using overtemperature and overvoltage, the process is alternated with tests of parameters to fully illustrate the processes expected in future designs.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124696618","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 main area of application of the observed multichannel synchronization system is satellite laser ranging (SLR) stations with several pulsed radiation sources. The possibilities of multichannel measurements will significantly increase the accuracy of measurements and open up new opportunities for scientists working in satellite positioning, synchronization, geodesy, etc. The concept of the developed multichannel system, including the proposed synchronisation method, is described. The prototype consists of five independent event timers, an AFG (arbitrary function generator), a reference clock active splitter, and a controllable equal delay multiplexer. The AFG generates a 10 MHz reference clock and an event signal (1 PPS). All five event timers and a controlled delay multiplexer are connected to the PC from which they are controlled. The thermal chamber was used to organize measurements of thermal stability. The temperature in the thermal chamber was changed from 15 to 30°C, and the initial calibration of the system was carried out at a temperature of 22.5°C.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126517347","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 electrolytic capacitors despites their excessive properties in terms of affordability, power density to volume and weight, remains an element that can cause device fail. The paper is dedicated to a solution to diagnostics, monitoring and prediction of remain lifetime of electrolytic capacitors. The main idea is that ESR (Equivalent Series Resistance) of capacitor grows while capacitor is getting to the end of the lifespan. ESR in combination with the capacitance is forming a Left Half-Plane zero and thus change in listed parameters is affecting overall transfer function. This paper uses buck converter as an example. The data for capacitors models is obtained from real accelerated aging experimental results. Modelling at different lifespan periods shows change in response to disturbance. The paper proposes to use band-pass filter to get signal that is easy to process further. The paper also has a little discussion on potential uses of the signal and their advantages and disadvantages.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133252416","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 aim is to evaluate and compare the performance of forecasting methods, such as machine learning and neural networks when forecasting CO2, Temperature and Humidity sensor data. The research methodology entails finding and employing widely used algorithms to conduct experiments aimed at forecasting humidity, temperature, and CO2 sensor data. The models Long Short-Term Memory (LSTM), Convolutional Neural Network (CNN), and Vector Autoregressive (VAR) model were implemented and used in the experiments. The findings reveal that the LSTM model demonstrates the lengthiest training duration but has consistent performance across all evaluation metrics. In contrast, the VAR model excels in temperature forecasting with reduced training times but exhibits inferior performance in forecasting humidity and CO2 levels. The CNN model, however, consistently underperforms in comparison to the other two models, particularly in humidity and CO2 forecasting. Results show that model selection is contingent upon the specific problem and data characteristics, with LSTMs being more for scenarios with long-range dependencies, and VAR models being advantageous for linear and stable relationships between variables.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128425740","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}
