It is shown that during avalanche, up-to-date technology MOSFET transistors exhibit a resistance far in excess of their on-state resistance (R/sub DSon/). A novel test setup is proposed to measure \"avalanche\" resistance. A simple model of breakdown voltage is then proposed. It becomes possible to perform fast simulations using this model to study current balance between paralleled transistors under avalanche operation. It is shown that considering avalanche resistance reduces the influence of breakdown voltage mismatches and allows for better current sharing.","PeriodicalId":100635,"journal":{"name":"IEEE Power Electronics Letters","volume":"2 3","pages":"104-107"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/LPEL.2004.839638","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50225502","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 dimming function is achieved by increasing the switching frequency of the inverter from the natural frequency of the resonant tank, so that less energy is coupled to the lamp. Control of the switching frequency is based on deriving an adjustable dc current source from the inductor in the resonant tank to control the operating point of the saturable chokes for driving the switches in the inverter. The overall circuit does not require any integrated circuit. A 17-W prototype has been built and tested. Theoretical predictions have been verified with experimental results. The lamp can be dimmed to 10% of the full brightness.","PeriodicalId":100635,"journal":{"name":"IEEE Power Electronics Letters","volume":"2 3","pages":"87-91"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/LPEL.2004.838777","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50225496","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}

Continuous grid monitoring should be considered so as to provide safe connections and disconnections from the grid. This letter gives an overview of the methods used for online grid measurement with PV inverters. Emphasis is placed on a method based on the injection of a noncharacteristic harmonic in the grid. Since this injection is regarded as a disturbance for the grid, different issues, i.e., the influence on total harmonic distortion (THD), the accuracy of line impedance measurement and the ENS (German abbreviation of Main Monitoring units with allocated Switching Devices) detection are studied. Laboratory results conducted on an existing PV inverter are presented to demonstrate the behavior of the PV inverter under different grid conditions. Some of the injection parameters are tuned in order to get an accurate measurement of line impedance.","PeriodicalId":100635,"journal":{"name":"IEEE Power Electronics Letters","volume":"2 3","pages":"77-82"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/LPEL.2004.834921","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50225495","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 general equation of the current ripple is obtained. By means of this equation, it is shown that the two strategies commonly used for the bridge control (unipolar and bipolar) are two limit cases of a general method. The control condition with minimum ripple is found. Finally, experimental results of a typical example are shown (applied to a DC drive) in different conditions, thus confirming the theoretical results.","PeriodicalId":100635,"journal":{"name":"IEEE Power Electronics Letters","volume":"2 3","pages":"83-86"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/LPEL.2004.837748","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50425690","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}
