The basic operation of the new inverter is compared with the conventional series inverter. The paper also shows that, in the output clamped inverter, the load variation has a negligible effect on the ringing period. Finally, the logic requirements and implementation of an output clamped series inverter system for a portable line operated power supply are discussed.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117002366","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, there appears some steady-state error on the crossregulated output voltages even though all windings of the reactor are ideally coupled. In this paper, the precise analysis for the cross-regulation phenomenon is performed by means of state-space averaging method. From this analysis, we clarify that the cross-regulation error arises due to the internal resistances of the circuit. Furthermore the dynamic characteristics such as the frequency responses and the stability are analyzed in detail.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117144952","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 the results of comparative analysis, it is revealed that this new converter is superior to the conventional one in the steady state and the dynamic performances. Further, it is demonstrated experimentally that the cross regulation performance of this new multiple-output converter is less affected by the leakage flux in the energy-storage reactor, and also that this converter is very useful as a preregulator for the continuous series regulator in cases requiring a high degree of regulation of the multiple-output voltages.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121530491","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 generation of energy transfer regulators has been developed based on the principle of charge controlled conversion. This principle is described and illustrated on a particular application: the MC2 (charge controlled modulator) in a boost configuration. It is shown that such a principle allows to combine brilliant dynamic performances, stress condition protections and high power regulation. A linear continuous mathematical model of the MC2 is detailed to support the bread board performances. These are performed bt using an automatic computer facility (APSEF) allowing fast and accurate measurments. It is finally shown that such a principle is a unique way to reach high power level (1 KW per module) in a reliable modular configuration.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126154604","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}

Each channel accepts input in the +10V range and outputs +1500V. into a capacitive load of 0.05 μf. The design employs a system of predictive incremental resonant charging (PIRC) of the load, controlled by a system clock. Central to the concept of PIRC is a means of calculating switching time for hot-switching transistors. Internal losses are minimized to hold size and weight to a minimum. The amplifiers as designed are flat in frequency response from dc to 4 kHz, and to 400 Hz without slew rate limitation. The system is intended to drive piezoelectric actuators of an adaptive optics mirror system, but the concept is applicable to any capacitive load. An overall design of the system was completed, and a two-channel breadboard was constructed, debugged, and tested. The tests showed that the system design requirements were met with only minor deficiencies.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127494365","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}

Similarly, series snubbers (di/dt limiting inductors) are used to reduce the turn-on switching loss or prevent forward- biased second breakdown. In both cases, energy is stored in the reactive element of the snubber and dissipated during its discharge. If the circuit includes a transformer, a voltage clamp across the transistor may be needed to absorb the energy trapped in the leakage inductance. The action of these typical snubber and clamp arrangements is analyzed and applied to optimize the design of a flyback converter used as a battery charger.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129396321","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}
