These parameters will be analyzed how to affect the capacitor life and thus the life of EV PCU. Firstly, the LCR meter tester was used to test the film capacitors, but it fails to measure ESR and ESL accurately because they are too small. So, a testing method is developed to detect these parameters of the film capacitors. The test method is mainly based a function generator, a power amplifier, current sensing resistor and a 16-bit, 2MS/s/ch A/D card. The acquired data are processed through Fourier Transformation (FT) to get the accurate amplitudes and phases of both the current and voltage of the tested capacitor. The experimental results show that the developed method provides a reliable procedure to measure the characteristics of film capacitors, which can be also used to monitor the health of the film capacitor online.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130052685","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}

IT2 T-S fuzzy system is proposed to control speed and current of a PMSM. The IT2 T-S fuzzy model of a PMSM is first derived from its nonlinear dynamic model. Next, the IT2 T-S fuzzy controller is designed via parallel distributed compensation (PDC). The stability conditions of the proposed controller are obtained by Linear Matrix Inequality (LMI). The encoder signals are implemented to calculate rotor speed and rotor position. The three-phase winding currents are properly sensed into the microcontroller. The corresponding duty ratios of power switches are determined using IT2 T-S fuzzy controller. Finally, the driving performance is validated via experimental results. Moreover, the interval type-1 T-S fuzzy control is compared to verify the improvement in driving performance.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130060543","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 adoption of medium-voltage Silicon Carbide (SiC) devices in motor drives can improve motor system’s efficiency, power density, and dynamic response. But the high switching dv/dt (short rise time) produced by SiC devices increases the stress on the motor winding insulation and leads to partial discharges. This paper studies the partial discharge in the medium-voltage motor winding subjected to two-level PWM waveforms produced by medium-voltage SiC devices. Partial discharge inception voltages (PDIVs) and repetitive partial discharge inception voltages (RPDIVs) of the motor winding at various rise time, switching frequencies and modulation index are tested.

The characteristics of the cell in the battery pack are different in resistance and capacity due to the manufacturing process and temperature unbalance.

In the proposed method, the sensor fusion method is used to update the characteristics of cell in battery pack and overcome the inaccurate measurement values of sensor. Since the battery management system (BMS) usually measures the voltage of the cell in battery pack, the proposed algorithm is constructed by using measurement fusion which fuses the sensing value (voltage).","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132723155","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}
