They can handle different voltage and power levels, provide a bidirectional and highly dynamic power flow and require relatively small dc-link capacitors. However, 3ph-MAB converters suffer from poor low-load efficiencies due to hard-switching operation. This paper introduces a new soft-switching operation strategy for 3ph-MAB converters, the so-called parallel-phase operation (PPO), to overcome this disadvantage. Furthermore, a novel multiport duty-cycle (MDC) operation is introduced for 1ph-MAB converters which enables soft switching of all ports. The advantages of PPO and MDC are exemplarily demonstrated for a three-phase triple-active bridge (3ph-TAB) converter, i.e., a 3ph-MAB converter with three ports. The 150 kW converter prototype interconnects a 5 kV medium-voltage dc-demonstrator grid using 10 kV SiC MOSFETs with two low-voltage dc grids with nominal voltages of 760 V and 380 V. Simulations show efficiency gains of more than 25% for low-load operation. The impact of PPO and MDC on the design of the semiconductors, the dc-link capacitors and the transformer is analyzed. Based on this analysis, design challenges of the converter as well as further improvements of MDC operation are discussed.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116726689","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, these motors call for more advanced control techniques, due to the rotor anisotropy and the nonlinearity of the magnetic circuit. Reliability and cost also push towards sensorless solutions. Often, the fundamental-frequency based techniques are preferred to the high frequency injection, for the noise and vibrations that the latter implies. Unfortunately, the former cannot work down to zero speed. The aim of this paper is the study and development of a simple and effective start-up technique for sensorless synchronous motor drives. Merged with fundamental-frequency based sensorless control, it yields a full-range ac drive that fits for many applications that do not require steady state operation at low/null speed. In particular, the paper paves the way for integrating the motor model in the start-up design, highlighting pitfalls of the standard methods and showing how to improve the transition to the closed-loop control.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121687159","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}
