But this circuit has the problem of high voltage stress at light load operations especially during the preheat and startup operations of the lamps. Based on the analysis of the operation principle, the following solution was proposed. With the introduction of a second resonance stage, the voltage stress in this ballast was reduced by half. The experimental results are provided for verification.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"26 1","pages":"887-893 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78204607","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}

This converter can be operated with PWM control because ZVS operation is achieved with an auxiliary resonant circuit that has few switching losses and handles much less power than the main power circuit as it is activated for only a small fraction of the switching cycle. Moreover, peak switch stresses are lower than those found in other proposed converters because some of the energy circulating in the auxiliary circuit is fed to the load. In the paper, the modes of converter operation are explained and analyzed, design guidelines are given, and experimental results are presented.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"104 1","pages":"76-82 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80470873","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}

As a relatively new power semiconductor device, little effort has been made thus far in creating an accurate model used for simulation. The only MCT model available to date is that based on the two bipolar transistor-behavioral subcircuit model. This model works well for static operation, but it has limitations in predicting the dynamic behavior of the device due to the omission of the internal device physics. The use of the lumped-charge modeling technique facilitates the inclusion of internal physical processes and the structural geometry of the device into the model. As a result, this technique provides a more realistic and accurate model than any other presently available. This model is verified through Saber(R) simulation and experimental results.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"9 1","pages":"23-28 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79910287","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 sliding surface of the sliding mode controller is designed such that the behavior of the controlled PWM inverter system is optimal, subject to the defined cost function.
