To measure the component stress, a one phase test circuit, in which the semiconductor devices are stressed in a way similar to that in real resonant inverter systems, is described. A detailed investigation of semiconductor losses and passive component losses depending on parameters of the resonant tank is given. For the measurements fast switching and low saturation IGBTs were used. A comparison of semiconductor losses in an active clamped resonant DC link inverter and in a hard switched PWM inverter is given.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131000409","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 improved sampled-data model is recommended for use in conjunction with other techniques in determining exact small-signal input-to-output frequency responses.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115752896","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}

A new multirate low-frequency sampling PWM scheme is introduced that not only provides the possibility for new types of operation, but also unifies the switching logic corresponding to established PWM schemes. An exact nonlinear discrete-time model is used to develop multirate nonlinear controllers and observers based on map-inversion concepts. This nonlinear design methodology is widely applicable, requiring only that the continuous-time small-signal average model be controllable and observable.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123964338","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 bridged chopper has two switches which alternately conduct. The duty cycles of the conduction of the switches are complementary with one another and are varied to control the output voltage. Three resonant circuit configurations which are suitable for this type of control are presented. Frequency domain analysis of the converter is given and performance characteristics are presented.
