In the conventional electrolytic capacitor-less single inverter, harmonics caused by the DC-link voltage ripple frequency are superimposed on the motor phase current under a distorted input voltage. As a result, the reliability of the motor drive system is reduced, and the torque ripple causes mechanical vibration and noise. Using the proposed control method, the compensating inverter outputs the harmonic voltage superimposed on the estimated motor winding voltages. The experimental results show that compared to the conventional electrolytic capacitor-less single inverter, the proposed system reduces the maximum peak-to-peak of motor current by 8 %, and the shaft torque ripple caused by a distorted input voltage by 75 %. For motor drive systems without energy buffer that are driven under a distorted grid voltage, the proposed control method improves reliability and reduces mechanical vibration and noise.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"9 37 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":"115907251","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 the meantime, the modified STDA (MSTDA) is proposed based on MFHA and STDA, which is also more accurate as the working frequency is close to the series resonant frequency.

These components are usually filtered as the VSI is intended to transfer power only at the grid frequency. The proposed converter exploits the possibility of power transfer at both the grid and switching frequency. As usual, power is transferred to grid at the fundamental grid frequency by suitable inductive filters. On the other hand, power is transferred to the DC side at switching frequency, thus achieving high frequency galvanic isolation; this is made by means of three resonant tanks (connected to each VSI phase) and a single, phase-shifted, active bridge at the DC side. This configuration allows the bidirectional power transfer with the simplicity of the VSI for the grid side, and the features of the Dual Active Bridge Series Resonant Converter at the DC side (ZVS, power control by means of shift angle). The operation of the converter is detailed, and the steady state power transfer is analyzed, simulation results for a 2.4 kW prototype are presented as validation.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"135 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":"131507096","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 new branch is installed in parallel with the arm inductors, and it includes a partially rated dc-ac converter which enables power exchange between the ES and the arms of the MMC in the form of a higher harmonic current. The topology adds new functionalities to the MMC substation without affecting the existing configuration; the ES branches are connected to the MMC in the existing busbars. The solution enables an addition up to 0.4 pu power from the ES for a typical rated high voltage MMC.

Thus, in this paper, a fast detection method for short-duration grid voltage RMS variation is proposed to accelerate the response of the DVR based on 4 approaches, achieving low time delay less than 1ms in most cases even for the grid voltage with distortions.
