Making its right choice will ascertain the range anxiety, maximum speed and battery ratings required for the electric vehicle. The radical increase in the cost of rare earth magnet materials has pressurized all the countries to come up with rare earth magnet free motor as the traction choice. Interior permanent magnet synchronous motor (IPMSM) is the most widely used one although it suffers from the risk of demagnetization at higher temperatures. Due to the aforesaid reasons its popularity is diminishing. This scenario clearly indicates the requirement of feasibility check for Synchronous reluctance motor (SynRM) as the traction choice. This paper provides an in-depth discussion about the performance analysis of SynRM under the following heads: Peak torque capability, continuous thermal envelope, inverter rating and drive cycle analysis. Here the efficiency maps across the entire speed and torque range is studied with Worldwide Harmonized Light Vehicles Test Procedure (WLTP) Class 2 drive cycle. Thereafter these performance indies are compared with an IPMSM of comparable power rating. Another important aspect highlighted here is the tradeoff study between cost, weight and efficiency of the designed motor that will bring in a holistic picture.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":"70 6-7 1","pages":"100-106"},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88843625","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}

To enable the use of these inverters with motors without specially reinforced insulation the voltage slopes need to be slowed down. This article presents a new low-loss countermeasure, which involves the parallel connection of two half-bridges via an interphase transformer. For this one half-bridge is delayed relative to the other one by a delay tuned to a resonant circuit. Undesired DC components in the cross-current of the interphase transformer occur due to non-idealities in the voltage symmetry. The subsequent DC magnetization ultimately can cause the core to saturate. The paper describes the effects due to inaccurate timings and the aspects to keep in mind when dimensioning the magnetic core. Also, this article describes an approach to deal with the undesired current components using a closed-loop control. For that, a special differential-mode shunt is used which enables a dedicated measurement of the cross-current mean value and mitigates the influence of the switching frequency. Finally, the controller concept is presented. The controller is implemented and verified on a 500 kVA SiC inverter test bench.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":"65 1","pages":"205-211"},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74007213","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}

In this experimental investigation, a thermoelectric generator, as highly reliable solid-state device, and a box containing phase change material are integrated to a concentrated triple junction solar cell in order to enhance the utilization of the solar energy. The triple junction solar cell and the thermoelectric generator are characterized by measuring the I-V-P under different solar concentrations. In order to evaluate the impact of using PCM, the obtained performance of the hybrid system and the short circuit current, open circuit voltage and maximum power for its two components are compared in steady state and transient regimes with the hybrid system without the PCM. The results indicate that enhancement of the concentration ratio has opposite impact on the efficiency of the thermoelectric generator and the triple junction solar cell. Furthermore, the phase change material box has a more considerable impact on the power generated by the thermoelectric generator than the triple junction solar cell for both regimes.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":"28 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78311680","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}
