This always requires dozens of PV modules, however some of them maybe suffer from partial shadow caused by trees, clouds or other things. In this case, power generated from each PV module becomes unbalanced so that total output powers greatly decrease. Furthermore, hot-spot effect caused by partial shadow is likely to damage the PV cells and affect the security of PV system. In order to solve these problems, a novel topology of PV system composed of many series-connected PV modules with corresponding energy feedback circuits is proposed in this paper, a feedback circuit is independently utilized to feed the output energy of PV system to the corresponding circuit including shadowed PV module. The simulation and experimental results verify that the proposed topology can make each PV module operate on the maximum power point individually regardless of partial shadow. The energy feedback circuits do not operate without partial shadow, they have no power loss under this condition, therefore the circuit efficiency is improved.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132381193","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}

Dual-loop control for PWM inverter can achieve fast dynamic response and inhibit nonlinear load disturbances while observer can solve the problem of duty-cycle regulation caused by sampling and computing delay, and repetitive compensation to state observer could reduce the predictive error induced by model deviation. First in this paper the mathematical model of PWM inverter is established based on the state-space theory, using state-average method. Then a digital dual-loop control (inner loop is inductor current and outer loop is output voltage) with output current feed-forward is adopted. In order to get predictive value of feedback variables, observer is introduced and designed. Meanwhile, repetitive compensation is accordingly added to state observer to increase prediction accuracy. Finally the control method mentioned above is validated by experiment on a 50Hz single-phase PWM inverter. Results show that this method could obtain nice dynamic and static characteristics under various loads.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125432136","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 machine model is based on the stationary reference frame with vectorized dynamic model and control unit is based on the line-voltage oriented reference frame. The machine side converter provides good decoupling between the active and reactive power and the network side converter controls the power flow between the DC bus and the AC side and allows the system to be operated in sub-synchronous and super synchronous speed. The induction machine runs at a specific speed with the stator disconnected from the grid (Is=0), the rotor is suddenly excited with slip-frequency voltages derived from voltage regulators so as to produce commended open-circuit stator terminal voltage. Behavior under varying input power typically observed in wind turbines is also reported. A MATLAB computer simulation study was undertaken and results on 1.5 kW wind turbine are presented indicating grid abnormalities and varying input power.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123258308","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 induction heating is often used for the heat-treatment of a metal work-piece. In hardening of a gear, since the bottom or tips are heated at lower frequency fL or higher frequency fH respectively, the heating at two different frequencies for uniform heat-treatment is required. Therefore, two inverters are necessary to output different resonant frequency each other. To solve this problem, a single adjustable frequency quasi-resonant inverter circuits which have the short-circuit switch across a capacitor have been reported [1]. This inverter circuit includes the first resonant capacitor and that of the second with a one-way short-circuit switch. Synthetic series capacitance is varied by manipulating the on-time of the switch and then the resonant frequency can be adjusted. Insulated Gate Bipolar Transistor (IGBT) is used as the switching device of the circuit in [1]. The proposed circuit cannot realize with the IGBT to output the high frequency of 100kHz or more. The circuit uses the Power MOSFET instead of the IGBT. Otherwise, the device has the disadvantages of withstand voltage and current. However, this problem can be solved by the methods of connecting switching devices to series and using step down transformer. As an example, we could obtain the dual frequencies of 400kHz and 160kHz with the proposed single inverter composed of the Power MOSFETs.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121285421","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}
