This newly proposed design method is based on the calculation of its sensitivity function and design of the system so as to minimize its sensitivity function. In addition, investigation was finally carried out to prove that designing a modified repetitive control system with corrected dead time according to this newly proposed method provides for great improvement in its control performance. The overall results of the investigations thus conducted by the authors revealed that a modified repetitive control system with corrected dead time, if so designed using the newly proposed method as to minimize its sensitivity function, can achieve further improvement in its control performance.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114814007","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}

Single or parallel use of these modules can provide coverage of the whole motor range of GTO inverter systems for traction applications. The IGBT modules consist of newly developed IGBT chips with improved terminations for high blocking voltage and soft and fast recovery mode chips with high reverse recovery di/dt capability. The new IGBTs have a lower switching loss as compared with a conventional IGBT. A baseplate with low thermal expansion extends their fatigue lifetime to more than 5 times that of a conventional module. Low thermal impedance is achieved by a simple mode structure with optimal arrangement of IGBT and diode chips for both thermal and electric characteristics. Solder and wire-bonding reliabilities of the modules are kept high throughout the fatigue lifetime despite their large size.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132445017","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}

Combi-IC TDA 16888 includes the pulse width modulated (PWM) control for a SMPS and the control for the preconverter to improve the power factor and to reduce the harmonics of the AC input current. Both sections are internally synchronized on the same operating frequency. The preferred topology of the PFC-preconverter is boost, but flyback is also possible. The PWM section can be designed as a forward or as a flyback converter. Maximum duty cycle of the PFC is about 95%, in order to achieve minimal line current gaps. Maximum duty cycle of the PWM is limited to 50% to prevent transformer saturation. In normal operation the PFC section operates with dual loop control. A first control loop controls the shape of the line current by average current control enabling either continuous or discontinuous operation mode. The second loop controls the DC bus voltage. There is a third control loop available that enables the PFC section as an auxiliary power supply even during disabling the PWM section. In this paper the PFC preconverter, PWM converter, PFC and PWM gate drive, and oscillator and synchronisation are described.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123448512","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}

For example, the transmission power of the AC power line depends on the interconnecting line impedance between the two places. A new compensating method of inductance using variable active-passive reactance (VAPAR) has been proposed to control the existing reactance of a power circuit. In this paper, first, the authors propose an improved control method of the VAPAR to suppress resonances of the output voltage and current caused by the output filter using a state feedback method. The produced virtual impedance becomes the desired virtual inductance up to the limited frequency. Then, the frequency characteristics of the virtual inductance generated by the VAPAR is analyzed to clarify the relationship between the frequency characteristics of the virtual inductance and transient response through simulations. From these considerations, the design method of the required characteristics are discussed.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124207220","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}
