A voltage sensor is employed to measure the terminal voltage of the inverter. The phasor of the measured terminal voltage (phase-A) of the inverter has the same angular frequency as that of the back electro-motive force (emf) of the PMSM. Therefore, the angular frequency of the measured terminal voltage is used for computing the rotational speed of the PMSM. A simplified dynamic angle compensation term is derived that calculates the phase/angle shift between the terminal voltage phasor and the back emf phasor. The calculated phase/angle shift (angle compensation) in terms of time is then used to time-shift the terminal voltage phasor to obtain the exact rotor position of the PMSM. This proposed method does not require any complex estimation/observer based algorithm. The estimated rotor position and mechanical speed are employed for the vector control of the PMSM. A 1 kW laboratory prototype is developed and tested to assess the effectiveness of the proposed method. The proposed rotor position estimation approach is capable of estimating the rotor position with less than 1% error and consequently, tracks the reference speed with less than 0.1% steady-state error.","PeriodicalId":201289,"journal":{"name":"2017 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122720022","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}

It presents a theoretical analysis, a design consideration, and experimental results. In the conventional adapter applications, 2-stage configuration shows higher power transfer efficiency and higher power density than those of the single stage flyback converter. In the 2-stage AC-DC converter, the boost converter is widely used as a front-end converter. It provides continuous input current and power factor correction. However, an efficiency variation between high AC line and low AC line is large. On the other hand, the proposed conduction band control method for a buck front-end converter has an advantage of small efficiency variation. In the proposed control method, switching operation is determined by a band control voltage which represents output load condition, and an AC line voltage. In half of line cycle, if the instantaneous line voltage is lower than the band control voltage, the buck converter operates and transfers power to the downstream converter. On the contrary, if the instantaneous line voltage is higher than the band control voltage, the buck converter stops switching operation. Thus, the proposed control method reduces switching loss under high AC line and light load condition. A 60W prototype which is configured the buck and LLC converter with the proposed control method is experimented on to verify the validity of the proposed system. The prototype shows 92.16% of AC-DC overall efficiency and 20.19 W/in3 of power density.","PeriodicalId":201289,"journal":{"name":"2017 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114741670","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}
