The half-bridge LLC converter is used as a DC battery charger in a solar powered charging station for electric bicycles. The LLC resonant converter was selected for this application due to its inherent soft switching, high efficiency, ability to operate at high switching frequencies, and has a relatively wide voltage range. The predictive control algorithm provides regulation of the output voltage to the set point. The switches of the converter are controlled directly, i.e. without using a modulator which implies a variable switching frequency.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123787996","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}

By decrease of the input voltage the converter exhibits quasiperiodicity caused by Hopf bifurcation and border collision bifurcation. In the area of these bifurcations mode locking, quasiperiodic steady-states and chaotic steady-states alternate. Characteristic waveforms, trajectories and harmonic contents of the input currrent in the area of Hopf bifurcation and border collision bifurcation are presented. The quasiperiodicity caused by both bifurcations has so far not been recorded in the boost converter. Additional harmonics in the input current of the converter are introduced by the quasiperiodicity. These harmonics are spread to the area of frequencies lower than the switching frequency as well as between the multiple integers of the switching frequency. Low frequency AC components in quasiperiodicity caused by border collision bifurcation are higher than low frequency AC components caused by Hopf bifurcation. These low frequency harmonics can be harmful to the source of the input voltage.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125986676","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}

For example, if we wanted to use these types of transistors in an inverter system in which the DC link reaches a voltage of 800V, we would need a transistor with a minimum blocking capacity of 1000V (including a margin of 20%). Therefore, it is possible to use SiC transistors or GaN transistors connected in so called stacked configuration, thus doubling their blocking ability. If 650V transistors are being used, their blocking capability in stacked configuration would be 1300V. There are several advantages to use this configuration, but it also exhibits negatives related to issues described within proposed paper. The paper deals with the design of a high voltage stacked configuration GaN module, while it describes simulation analyses, practical PCB design and initial experimental tests.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132393701","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 similarity of these applications and multilevel nature of the batteries logically encourages building of the interface converters based on a multilevel scheme. This paper is devoted to the choice of the configuration of this scheme and its operation mode. Tentative quality evaluation is made based on the root-mean declination of output voltage from its reference (THD). MATLAB-Simulink simulation is chosen as a reasonable data collection method. The results of the simulation show that a trade-off configuration may include 3-4 levels with minor inter-level pulse width modulation. In the same time further investigation must be done in order to study the influence of other technical (losses) and economical parameters.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"310 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115915359","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 novel machine concept is easy to fabricate and can be scaled by the number of U-core laminations to meet different requirements for output torque and power. It shows a high torque-to-weight ratio and has an excellent utilization rate of the magnet material. In this paper, the adaption of the AxMDM concept for a propeller drive is discussed. One of the main challenges for the aviation application of electric motors is a dust robust air-cooling approach. Therefore, an encapsulated air-cooling system for the AxMDM concept was developed. The impact of the minimization of the phase elements of the motor will be introduced, followed by an investigation of the temperature behavior of the motor at variable motor speed and current injection. In the last section, the temperature behavior of the motor at nominal and maximum operating conditions will be presented.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124832899","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 a second step the turn-on and -off losses of a single GaN HEMT are measured for different current, voltage and temperature values, using a double pulse test fixture. These evaluated losses are used to create a loss model of a single switch and finally a model of the 3L-ANPC.

The transformer is used to deliver energy to an electronic equipment mounted on the head of drill machine. In order to increase energy efficiency and power density the capacitance compensation system for leakage inductances is applied. Since the secondary is movable, an analysis of generation of the energy resulting from spatial changes of magnetic field is carried out. The analysis presented in the paper is based on ANSYS software and is carried out mostly as harmonic one for linear models.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129938939","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}
