For this reason, it first reviews the known methods and proposes a new classification, based on the number of independently set parameters for the process. Based on the classification it is noted, that a power converter that has the ability to charge or discharge a battery, along with accompanying software to enable the user to implement a custom charging algorithm is able to implement most of the types of mentioned charging/formation techniques. The design of such a converter, capable of delivering up to 600W is presented, after a short review of the possible power topologies that can be used to implement it.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133196239","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 proposed soft-switching inverter is formed from the traditional pulse-width modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is achieved through applying PWM switching control signals with suitable delays for the switches. The designed soft-switching inverter is used for powering an induction motor drive which is connected to drive the constant nominal load. The converter is designed to achieve the maximum voltage gradient and simultaneously to have low peak current and voltage stresses on the devices and thereby to reduce the losses.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125096278","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}

It is a method of locating objects using sound receivers — TDOA (Time Difference of Arrival), a part of multilateration (MLAT) method used to locate mobile phones, civil aviation aircraft, locating military objects, and more. Also is presented a lightweight algorithm for calculating coordinates of the localized object based on measured times by sound sensors. An overview of the problems to be overcome is made. Suggestions for decisions were made allowing the implementation of the system into a real embedded project. A scheme for implementing the system has been proposed. The limitations of the measurement method in terms of practical implementation are defined and some ideas are outlined to minimize these limitations. The application of such systems is a training and training purpose, sports shooting equipment, applicable to other games using targets and requiring electronic reporting of the result.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"476 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128306583","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}
