A head-mounted DBS device is taken into account in the design procedure of the presented WPT system. A three coil system is designed to provide high efficiency power transfer. The LCC compensation network which has constant voltage characteristic is used in the transmitter side and two receiver coils using series compensation are located in the receiver side, into the human tissue. Finally, performance of the proposed WPT system is tested by a 3D electromagnetic simulation work at a 10 mm distance. Based on the simulation results, 1.19 V DC output voltage is regulated while the DC output current is 24 mA. The power transfer efficiency is achieved as 4.63% at full load condition.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116370285","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}

This requires new approaches to ensure system safety. Looking at standards like ISO 26262 or ISO/PAS 21448 and their suggested methodologies, an increasing trend in the recent literature can be noticed to incorporate uncertainty. Often this is done by using Bayesian Networks as a framework to enable probabilistic reasoning. These models can also be used to represent causal relationships. Many publications claim to model cause-effect relations, yet rarely give a formal introduction of the implications and resulting possibilities such an approach may have. This paper aims to link the domains of causal reasoning and automotive system safety by investigating relations between causal models and approaches like FMEA, FTA, or GSN. First, the famous “Ladder of Causation” and its implications on causality are reviewed. Next, we give an informal overview of common hazard and reliability analysis techniques and associate them with probabilistic models. Finally, we analyse a mixed-model methodology called Hybrid Causal Logic, extend its idea, and build the concept of a causal shell model of automotive system safety.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125202120","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 following section describes the operation of the traction system in terms of interconnection with the distribution power grid. The important requirements for the behavior and used equipment of advanced traction stations are explained in more details here. The last part of this paper presents the proposed concept of control of individual traction substations, while superior power distribution control is not available. Therefore, each traction substation must have its own independent control algorithms, its behavior properties are presented and documented in the results of simulation models. In order to be able to explain the whole issue well, the created model is simplified only to the control of two independent traction substations.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122888135","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}

Measurement is based on a ferroelectric effect, creating hysteretic capacitance vs. bias-voltage (C-V) dependence of the ordinary multilayer ceramic capacitors. Voltage measurement is based on AC impedance sensing of a high-density multilayer ceramic capacitor and comparing with ground-referred matched capacitor with corresponding DC bias voltage. Corresponding DC bias voltage is provided by negative impedance converter and a feedback network. Despite finite accuracy (~1%), voltage sensing performed by a capacitor can be advantageous as it allows to implement AC (high-voltage) coupling, and presents nearly ideal infinite input impedance. This can be beneficial in a variety of applications e.g. in power management systems, energy harvesting applications, or scientific instrumentation.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126509045","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 in the case of analog oscillators, it is also necessary to control the amplitude of digital oscillators with a sine wave. If the amplitude is not controlled, exponential increase or decay of the oscillation amplitude occurred, even if floating-point arithmetic is used. An example of digital sine recursive oscillator control with quadrature outputs, simulation results and design results are given in detail. Oscillator amplitude control is performed in a completely new way with a simple and fast algorithm for finding the maximum (minimum) and amplitude correction in case the amplitude differs from the desired value. The advantage is that the oscillator can be simply implemented by a program in the microcontroller.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122595629","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}
