However, this approach often leads to large execution times and uncertain results associated with convergence problems. Alternatives are switched-circuit simulators, where the switches are idealized by assuming zero on-resistance, infinite off-resistance and instantaneous switching. Though these simulators overcome the long execution times and convergence problems, both Spice-based and switched-circuit simulators have execution times proportional to the number of power switches. Furthermore, modern control techniques are difficult to implement. A practical and efficient solution that allows use of the discrete state approach is available today in the form of powerful and user friendly high level language compilers, such as C and BASIC. This paper illustrates the clear advantages of combining this approach with BASIC to simulate power converter systems. Moreover, the use of discrete states, instead of ideal switches, to model static power converters reduces execution time and introduces high flexibility in implementing complex PWM pattern generation algorithms, such as space vector or predictive control techniques, regardless of the power and control circuit structure and/or complexity.<<ETX>>","PeriodicalId":123138,"journal":{"name":"Proceedings of 1994 IEEE Workshop on Computers in Power Electronics","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117161807","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}

Its principle is to control, simultaneously, the levels of energy storage elements L and C in a simple way: a linear combination of the two state variables of the resonant circuit. This process notably favours HF DC-DC conversion, giving also fast dynamics close to those of optimal trajectory control. In addition, this method is very easy to apply analogically as well as numerically and in both cases the cost is minimal. Numerical simulation results confirm the performance of the linear control for the transient regime. This strategy can be easily applied to other types of resonance (parallel or series-parallel) operating at frequencies below and above the resonant frequency.<<ETX>>","PeriodicalId":123138,"journal":{"name":"Proceedings of 1994 IEEE Workshop on Computers in Power Electronics","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127089601","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 modulating template waveform is shown to be based on segments of a tangent waveform and is generated using the line voltage, the rectifier output voltage and the load current. The paper provides the analysis and the design of the controller and presents simulation and preliminary implementation results to demonstrate its effectiveness.<<ETX>>","PeriodicalId":123138,"journal":{"name":"Proceedings of 1994 IEEE Workshop on Computers in Power Electronics","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132244414","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}
