The insulation state of cable is related to the safety and reliability of power supply. In this paper, a cable insulation monitoring method based on signal injection is proposed. The low frequency signal is injected and the dielectric loss parameters of the cable are obtained. The insulation state of the cable is reflected by the dielectric loss parameter of the injected signal. Considering the accuracy of the injected signal in cable insulation monitoring, double terminal sampling is adopted. The variational mode decomposition and signal entropy are used to process the sampled signal and extract the injection signal to reduce the noise interference in the sampling signal. The feasibility and effectiveness of this method is verified by simulation.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123532877","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}

However, this technique fails to work on Surface Permanent Magnet Synchronous Motors (SPMSMs) under all load conditions due to lack of magnetic saliency. To overcome this drawback, this paper proposes an extended pulsating HF technique in which an artificial saliency is created by changing flux in the d axis, based on the knowledge of the load applied on the motor shaft. The consequent variation of the d and q axis inductances introduces sufficient magnetic saliency to detect the rotor position at all load conditions. Experimental results are presented to prove the validity of the proposed technique.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"182 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123573488","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}

Based on this method, this article has improved the Dual-Active-Bridge (DAB) converter optimization control strategy. Compared with the conventional analytical method, it avoids the process of solving the equations of the external shift compared to D2 and the internal shift compared to D1 and the voltage regulation ratio, and it also avoids the more complicated closed-loop system design. By discarding the condition that the partial derivative of the Lagrangian multiplier by the function is zero, the intersection point of several planes, that is, the continuous optimal trajectory, is obtained, thereby obtaining the optimal phase shift angle. An experimental prototype is built to compare the inductor current stress under the optimal solution combination with the stress of the non-optimal combination. The experimental results are consistent with the theoretical analysis, which proves the effectiveness and feasibility of the proposed method.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124487751","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}

This MIC is analysed for two inputs in this paper. As compared to existing MICs in literature, the proposed converter utilizes less number of inductors and requires only one switch to integrate any extra energy storage.

In general, the high CMV generates the large common-mode current, which causes electromagnetic emissions and motor damage. Also, the large DCC aggravates the lifespan and increases the size of the DC-link capacitors. Therefore, decreasing the CMV and DCC is necessary in the VSI systems. For this purpose, various PWM strategies, such as active zero-state PWM, near-state PWM, extended double-carrier PWM, and multi-carrier generalized discontinuous PWM, are reviewed. Furthermore, based on these PWM strategies, the PWM selection method is proposed to effectively reduce the CMV and DCC. The effectiveness of the PWM selection method is verified by simulation and experimental results with a permanent magnet synchronous motor drive system.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129400379","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 external casing convection has been experimentally identified. The contact resistance between components were computed using effective airgap.

Besides, the quantitative influence of the constraints remains to be analyzed. In this paper, a parameter optimization strategy based on the minimization of resonant current with multiple constraints is proposed, which effectively reduces the difficulty of the IBRDC parameter design and therefore has high engineering application value.
