First, a class D resonant backlight inverter is employed to act as the main circuit. Next, the phase angle variations caused by the parasitic capacitances is considered as a reference parameter in the proposed control strategy. By using the primary-side control and incorporating the DPLL technique to form a feedback mechanism to track the optimal operating frequency. And then the influence of parasitic capacitance can be reduced so as to eliminate the leakage current effect, hence, the system efficiency and stability will be improved.

Total input power factor of the DPC-based PWMCSR becomes worse as the load gets lower due to the low-order harmonics in the line currents, especially the fifth and the seventh. Since the dominant low-order harmonic currents cause an oscillation in the active power at frequency of sixth, suppression of the sixth-order harmonic active power is essential to improve the total power factor particularly in the low-load range. The paper describes a theoretical aspect and a suppression technique of the harmonic active power, followed by basic configuration and operation of the DPC-based PWMCSR. Effectiveness of the proposed technique is confirmed through computer simulations and experimental tests, using a 2-kW prototype. As a result, the total harmonic distortion of the line currents is effectively reduced by 10 %, which results in approximately 20-% improvement of the total input power factor at a 350-W load condition.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"1 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":"126618859","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, it cannot be dispatched like conventional generators because the power generated by the wind changes rapidly because of the continuous fluctuation of wind speed and direction. So it is very important to predict the wind power generation. This paper discusses why the wind power generation can be predicted in short-term, and how to setup the construction of an ANN (artificial neural network) prediction model of wind power based on chaotic time series. The analysis of modeling with low dimensions nonlinear dynamics indicates that time series of wind power generation have chaotic characteristics, and wind power can be predicted in short-term. Phase space reconstruction method can be used for ANN model design. The data from the wind farm located in the Saihanba China are used for this study.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"18 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":"127635237","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 triangular voltage obtained from a simple RC network connected between comparator output and converter output is superimposed to the output voltage and as a feedback signal to a hysteretic comparator. Since the hysteretic PWM controller essentially has derivative characteristics and has no error amplifier, the presented method provides no steady-state error voltage on the output and excellent dynamic performances for the load current transient by choosing proper values of time constants in the RC network.

Especially when applied to induction machines spatial saturation leads to a heavy dependence of the control signals on the flux/load level. This dependence has to be identified on a special test stand during a commissioning procedure. To avoid the usage of a speed sensor as well as load dynamometer coupled during the commissioning an adaptive flux model is proposed that delivers an accurate reference flux angle.
