In order to investigate their influence on the system's behavior in time domain, model which is accurate and simple enough to be integrated into circuit simulation environment, is desired.

With the introduction of wide-bandgap semiconductor drives, these issues will become more pronounced. This paper introduces a new type of dv/dt filter where the inductor, capacitor, and damping resistor are integrated into the output bus bar or cable of the inverter. This integrated filter may be smaller, lighter, and cheaper to construct than filters built from discrete components. An analytical model of the integrated dv/dt filter is developed, and this model is used to design output filters for a 460 V AC, 3-phase silicon carbide motor drive that meet the NEMA MG 1 Part 31 requirements for inverter-rated motors. Prototype filters are constructed and tested with a silicon carbide inverter connected to a 460 Vrms induction motor, and experimental results demonstrate output waveforms that match the analytical model and meet the NEMA requirements.","PeriodicalId":113756,"journal":{"name":"2018 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124570542","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 first proposed technique uses the redundant states of the CHB converter to generate different AC voltages to balance the SOCs of the CHB cells. For the first proposed technique, the active power injected to the CHB converter is calculated and the optimal switching state that can regulate the SOCs of batteries is designed before switching transitions. In the second proposed technique, the information of AC input current is employed to design the switching states at each quarter of the period. As shown in this paper, the two proposed techniques can regulate the SOCs of the multilevel converter much faster than two conventional techniques in literature without increasing cost or complexity of the converter. This can increase the battery charging speed on the grid-tied converter. The experiments are conducted on a 7-level CHB converter to validate the two proposed techniques.","PeriodicalId":113756,"journal":{"name":"2018 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124046572","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}

During normal operation (three-phase operation) the boost switch is disabled and during one phase loss is enabled. The analysis of one phase loss with combination of buck and boost (buck+boost) operation shows that the converter is able to deliver two-third of rated power and regulate the output voltage with maximum output voltage drop less than 4 % of nominal output voltage with significantly smaller output capacitor comparing with conventional buck matrix-type rectifier. The performance of the converter in buck and buck+boost operation is evaluated and verified by simulations and experiments on a 5 kW prototype.","PeriodicalId":113756,"journal":{"name":"2018 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129451698","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 such architectures, a tightly regulated point-of-load (PoL) converter resembles a constant power load (CPL) which introduces a negative-impedance effect to the source converter. This effect may introduce limit cycle oscillation (LCO) and may eventually destabilize the overall DPA. In this paper, a source buck converter is considered under digital current-mode control (DCMC) with a proportional-integral (PI) voltage controller, which is driving a CPL buck converter. During a power step-transient in the CPL, stable controller gain ranges under DCMC are computed for the source converter for individual operating conditions. Thereafter, a phase-plane based geometric framework is proposed to compute the optimal proportional gain for the source converter to achieve near time optimal recovery. A hardware prototype is made with 50 W nominal power ratings for individual converters. Analytical predictions and improved performance are validated experimentally.","PeriodicalId":113756,"journal":{"name":"2018 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127151356","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}

Each of the wireless battery modules includes its own power electronics for DC-AC power conversion for Wireless Power Transfer (WPT), regulation of voltage and State-Of-Charge (SOC), and wireless communication link with an on-board unit. The on-board unit combines the power received wirelessly from all of the battery modules (AC-DC or AC-AC conversion) and its master controller uses the voltage, current, and other information received wirelessly from the battery modules to wirelessly send back control commands in order to regulate the discharge (or charge) rate of each battery module. For example, in the Electric Vehicles (EVs) application this wirelessly controlled and distributed battery system or pack can potentially allow for exchanging or swapping the wireless battery modules in a safer, easier, and faster manner. This can potentially contribute to significantly reduced “Range Anxiety” phenomenon that is associated with EVs.","PeriodicalId":113756,"journal":{"name":"2018 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130563925","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}

By adding an air-core transformer before the rectifier for inductive isolation, the maximum output voltage can be twice the breakdown voltage of the insulation between the transformer's primary and secondary windings, thus allowing the implementation of a small, lightweight, and fast transient high-voltage dc-dc converter.

The high-frequency injection method which is commonly used in sensorless control and parameter identification algorithms yields significant torque ripple on the main generator (MG). Since the main exciter (ME) and the MG are mounted on the same shaft, in this paper, the torque of the ME is controlled to compensate the torque ripple of the MG, so that the ripple on the output torque can be reduced. A method which integrates the open-loop control of the field current of the MG into the closed-loop control of the torque of the ME is proposed. The effectiveness of this method is verified by experimental results.","PeriodicalId":113756,"journal":{"name":"2018 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129228792","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}
