These EI and EE core configurations eliminate many of the problems associated with the earlier single air-gap structures such as: high sensitivity of ripple currents to air-gap and/or turns ratio changes, complex winding arrangements and consequent high costs and inferior thermal characteristics. To facilitate the design, critical leakage parameter I is evaluated for a whole line of EI and EE cores.","PeriodicalId":164857,"journal":{"name":"1986 17th Annual IEEE Power Electronics Specialists Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129586247","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, MOS-GTOs generally require two control electrodes for turn-on, which might be regarded as a disadvantage. This paper shows that in MOS-GTOs with a p-channel cathode structure it is possible to turn the thyristor on and off by controlling only just one MOS gate electrode. As a triggering current for turn-on the MOS capacitance displacement current is used. MOS-GTOs with current gain βnpn = 30 and gate delay times of tgd = 8 µs were realized. Turn-on occurs homogeneously over the entire device. One-dimensional simulations indicate that thyristors with tgd = 1 µs can be realized, provided that βnpn 100.","PeriodicalId":164857,"journal":{"name":"1986 17th Annual IEEE Power Electronics Specialists Conference","volume":"26 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132149101","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}

Here the backward noise is defined as the switching noise which flows back to input terminals. Its generation process consists of several states and there are two modes depending on the characteristics of the switching elements used in the converter. The analysis is performed by deriving the high-frequency equivalent circuit corresponding to each state. The equivalent circuits include the parameters associated with the switching speed of a transistor and the recovery characteristics of a diode as well as inductive and capacitive parasitic parameters. As the result, the effects of these parameters on the backward noise are made clear quantitatively.","PeriodicalId":164857,"journal":{"name":"1986 17th Annual IEEE Power Electronics Specialists Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114632812","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}
