It is efficient in protecting the power switch during the turn-on and short-circuit transients and features an inherent feedforward of the input voltage. The implementation of the proposed algorithm can be realized by a very simple analog processor comprising only summing networks and comparators and could be done by means of a single dedicated integrated circuit. Beside being protected during the transients, the cells where this algorithm is implemented are insensitive to input filters; thus, simple and robust filters can be used at the input to ameliorate the waveshape of the absorbed current and the power factor of the installation. The theoretical background is confirmed by computer simulation and both are shown to agree with the measurements performed on a 380 V input 6 kW battery charger.<<ETX>>","PeriodicalId":169486,"journal":{"name":"10th International Telecommunications Energy Conference","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122088677","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}

In this approach, the step function is used comprehensively to represent switching information, demonstrating that the steady-state analysis of resonant converters can be correctly and precisely performed by existing methods in linear-network analysis. The proposed approach not only explicitly considers the influence of the parasitic resistor, but elucidates the physical implications of using a nonideal resonant tank. With the proposed approach, unified closed-form expressions for the voltage and the current of the resonant components can be easily found. The parallel-resonant converter operating at constant frequency is chosen as an example to show how to apply the theory to practical analysis. Analysis, simulation, and experiment are shown to agree very well.<<ETX>>","PeriodicalId":169486,"journal":{"name":"10th International Telecommunications Energy Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126436064","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}

These problems include compromises between the conflicting requirements to optimize the thermal transfer mechanisms with the need for insulation, safety, and condensation and corrosion control.
