First, the advantages and disadvantages of applying typical filter structures as a filter for grid connection of a three-phase inverter were analyzed. Next, filter design methodologies for grid connection of a three-phase inverter were analyzed, and an effective filter design methodology was determined to satisfy the harmonic requirements in grid connection. In order to verify the effectiveness of the design methodology, EMTP models such as a three-phase inverter, a three-phase LCL filter, and a performance evaluation system to evaluate the performance of the designed filter were developed using EMTP-RV. Next, an LCL filter was designed for an application example of a three-phase inverter, and the waveforms of the output voltage and outage current of the three-phase inverter were checked through EMTP-RV simulation work. In particular, the validity of the design methodology was verified by confirming that the magnitude of the current ripple was reduced to a limited magnitude through waveform analysis of the output current.","PeriodicalId":22843,"journal":{"name":"The Journal of the Korea institute of electronic communication sciences","volume":"5 1","pages":"261-270"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81182886","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 cause of high frequency noise, which occurs in some cases in the previous circuits under high gain conditions, was analyzed through simulations. Two mute switches were added to adjust each boosting gain for right and left ears more accurately by muting the sound of the other ear when adjusting the gain of one ear in the stereo hearing aid module.","PeriodicalId":22843,"journal":{"name":"The Journal of the Korea institute of electronic communication sciences","volume":"165 1","pages":"779-784"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75641096","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}
