This is achieved by using three phase cycloconverter based variable voltage variable frequency (VWF) drive. To realize this, a demand torque characteristic of a specific process machine is studied. The cycle duration of demand torque characteristics is divided into suitable number of time intervals. The subdivisions of time intervals in form of frequencies are tabulated to simplify design procedure. Change in frequency on particular subdivision results in demand torque of the induction motor. To meet this new frequency and voltage, three phase cycloconverter is designed with required frequency output. Finally to support theoretical analysis, simulation results are presented.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116760893","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}

Therefore, the proposed method has the advantage of simplifying the control circuit compared with the conventional perturbation and observation method where both current and voltage should be detected. A prototype based on the digital signal processor (DSP) controller is developed and tested to verify the performance of the proposed MPPT method. The experimental results show the proposed method has the expected performance.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127461995","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}

Firstly, a simulation model for flyback ac-dc converter is obtained by adding the rectifier and filter circuit to a flyback dc-dc converter model developed by the authors. The simulation results show that the processes of capacitor charging and discharging are independent, their boundary is near the maximal value of input voltage, and the part of flyback dc- dc converter can be seen as an approximately constant power load. Secondly, an analytic model for deciding the input power of flyback dc-dc converter with rated load and different input dc voltages is presented. Furthermore, the effect caused by the parasitical parameters in the electronic parts is studied, and the corresponding analytical method for deciding the input filter capacitance is given. The effect on the capacitance caused by the control delay is analyzed qualitatively.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127006567","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}

This paper presents an analytical dynamic model for TCSC to demonstrate how it consistently behaves in the large power system networks and efficiently stabilizes its oscillations in the case of a disturbance. The model for possible undesirable interactions between the PSS-type damping controllers and the TCSC damping controller is implemented by using the multi-machine model in the design stage. The proposed technique ensures that the designed controllers fulfill various practical requirements of the oscillation damping problem in power systems.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126542297","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}

This basic solution is simple to implement, but posing practical issues when it is applied to a four-wire three-phase system. The generalized theory of instantaneous powers has been proposed as an alternative to the optimal solution for a general three-phase system. Various simulations performed using this method, showing similar issues like those of the optimal solution for the four- wire systems when the power system is unbalanced or distorted. This paper mathematically shows that the optimal solution can be presented like the generalized theory, concluding no difference between the two methods but their appearances. Further, complementary analytical discussions are suggested to overcome the stated problem. Finally, the improved solution is simulated for an unbalanced distorted four-wire system. Comparing the complementary solutions with those of previously emerged generalized definitions confirms that the proposed solution provides almost a complete cancellation of source zero sequence current under unbalanced three-phase load voltages.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"26 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124309252","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}

This paper analyses the bifurcations in current controlled Luo topology operating in the continuous conduction mode by means of a continuous time model. The stability of the system is analyzed by studying the locus of the complex eigen values and the characteristic multipliers locate the onset of Hopf bifurcation. The 1-periodic orbit loses its stability via Hopf bifurcation and the resulting attractor is a quasi-periodic orbit. This later bifurcates to chaos via border collision bifurcation. A computer simulation using MATLAB SIMULINK confirms the predicted bifurcations. It has also been inferred from the experimental results that the margin of system stability decreases as the load decreases.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124312517","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}

And a new switching method for the current control of the amplifier is proposed. The proposed switching strategy is an improved version of the dead time minimization method, which can reduce current intermittence that commonly occurs with the conventional dead time minimization method whenever the current changes polarity. Dead time is not always adapted in the proposed method, which makes it different from the conventional practice of applying dead time in every current polarity changing point. In this paper, the specific strategy for the stereo operation is discussed. With the experimental results, usefulness of the control strategy is confirmed.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123795078","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}
