Although permanent magnet (PM) traction motors have been favored for their potential of higher power densities, the price and supply volatilities of PM materials are the major drawbacks. Instead of a single load point, the performance of a traction motor needs to be optimized over various combinations of torque and speed to represent real-world vehicular driving scenarios, which tends to be a time-consuming task with direct optimizations. In this paper, as a PM-free solution, a wound field synchronous motor (WFSM) is designed and optimized using a metamodel-based approach to maximize its efficiency over a custom set of load points, while utilizing a fully per-unitized geometry template. The workflow has proven to be timesaving and the selected design is prototyped.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"57 1/2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114105796","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 these motors, electronic pole changing is accomplished by changing the currents in certain windings by using an inverter. Although pole-changing transition on the fly has been explored in literature, the specifics as to when a pole change is required is yet to be established. This paper discusses the control of a 4-pole/2-pole induction motor where the controller initiates a pole change from one pole configuration to another to minimize the power loss of the motor when the operating region overlaps for the two pole configurations. Results from Simulink based on parameters extracted from Motor-CAD are provided to validate the control method. The pole changing control results demonstrate a smooth torque transition while minimizing the motor loss. The open loop experimental results are also given.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114340146","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 Phase-Locked Loop (PLL) has been the standard scheme for the synchronization and P/Q decoupling in grid-following inverters. Nonetheless, during transients, the PLL response is not ideal and causes oscillations or overshoots. Moreover, in adverse grid conditions, the PLL performance degrades significantly and loss of synchronism might occur. This paper introduces a structurally new scheme based on deep neural networks for synchronization, called DeepSynch. The method is capable of extracting the voltage phase fast and in a stable manner, even in a harmonic-polluted environment. The simulation results verify the performance of the proposed scheme.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114622728","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}

Doubly-fed Solid State Auto-Transformer (SSAT) concept for Multi-pulse Rectifiers 用于多脉冲整流器的双馈固态自耦变压器(SSAT)概念

Total harmonic distortion (THD) can be reduced by phase shifting the input voltage of MPR. But low frequency transformers used for phase-shifting are bulky. While autotransformers are used in several systems when isolation is not required, they themselves can be large in high power applications. Converting the input voltage into medium frequency (MF) or high frequency (HF) and using MF/HF transformers can significantly increase the power density. However, such a MF/HF ‘solid state auto-transformer’ (SSAT) has been difficult to realize. This paper presents a new doubly-fed SSAT concept for MPRs, where half of the power passes through a diode bridge directly and the other half flows through an SST to create the phase-shift (e.g. 30° for 12-pulse rectifier) with the original voltage before passing through the diode bridge. Simulation and preliminary experimental results based on a 12-pulse rectifier topology are provided in this paper as proof of the concept. Moreover, the proposed approach is compared with relevant MPR concepts from the literature with respect to size, efficiency, and cost.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116242453","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}

Nontheless, HF operation of the SiC devices emphasizes the effect of parasitics generating reflected waves phoenomena across the interconnection cables and transient overvoltage on motor terminals, reducing the life time and the reliability of electric drives. In this paper, the two solutions for the overvoltage mitigation of SiC-MOSFET based 2L inverter have been compared: the solution with an active gate driver based on digital control and the solution with an output dv/dt filter. The filter has been designed in order to meet the NEMA standard on voltage stress. The complete parasitic model of SiC-MOSFET based inverter has been developed in the LTspice simulation tool, as resulting from the experimental prototype pcb board and tested with the high frequency models of the motor in order to determine the overvoltages on the motor terminals. The two solutions have been compared in terms of efficiency, cost and volume, in order to have the clearest picture possible when comes to the judicious choice that practitioners in the motor drive industry have to make. These comparisons were carried out by realistic dynamic models of power devices obtained from the manufacturer’s experimental tests and verified both in the LTspice and PLECS simulation tools.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116243497","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 active power filter used in the frequency droop is correlated with inertia emulation, which affects the dc-link voltage. Furthermore, the coupling between active and reactive power in the low-voltage grid suggests a possible interaction between dc-link and reactive power control. The strong coupling between all the control loops and the dc-link in power synchronization-based converters represents a challenge both for the stability and for the controller tuning. This paper addresses the tuning of power synchronization-based converter with consideration of all the control loops interactions.
