Accordingly, more attention has been paid to measuring parasitic inductance extensively. However, the existing methods also have corresponding limitations, such as inadequate accuracy, complex measurement, and poor repeatability. Thus, a parasitic inductance extraction method for the arbitrary power flow path based on the parallel resonance principle is proposed in this paper. Compared with the methods proposed previously, the parasitic inductance can be extracted by only measuring the voltage of the parallel capacitor, which is a low-voltage and low-frequency damped oscillation attenuation signal. Finally, experimental results validate the effectiveness of the proposed method in measuring the parasitic inductance of the terminals of the silicon carbide power module.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132068633","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 paper, the LCC resonant converter is modeled based on fundamental harmonic approximation (FHA), and the output voltage ripple of a single module transformer is derived. On this basis, the output ripple of the multi-module LCC cascade converter is calculated and analyzed. Aiming at the problem that the ripple cancellation effect deteriorates due to the inconsistent parameters between modules, a phase locked loop (PLL) phase-shifting closed-loop control strategy is proposed.

Moreover, a lot of efforts are put by the industry to reuse retired EVs batteries in energy storage systems (ESS). To achieve optimal performance of the repurposed xEVs batteries in ESS, they should be similar in characteristic such as capacity, State of Health (SOH) and Remaining Useful Life (RUL). This makes the battery grading techniques to play a crucial role in it. Ohmic resistance measurement is a convenient way to evaluate the battery aging. However, conventional Electrochemical Impedance Spectroscopy (EIS) methods to measure ohmic resistance require complex curve fitting procedures while some others conventional methods are not much accurate. This research proposes a high-speed technique to measure ohmic resistance directly without using these curve fitting procedures. A Combined Phased Multi-Sine (CPMS) excitation is used to perturb the battery in specific frequency band. The require perturbation time is just 1 sec and ohmic resistance is measured using two impedance values. This makes the proposed technique several times faster than conventional EIS methods. The accuracy is verified by performing experiments on three types of Li-ion batteries. The obtain results shows less than 0.15% difference with reference conventional EIS method. This technique is suitable for grading mass xEVs batteries by evaluating their aging.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131355301","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}
