The DC-link voltage contains a ripple component with a twice power line frequency because of the configuration of the single-phase converter. Fed by such a fluctuating DC-link voltage, a severe beat phenomenon of the motor current occurs, which causes torque ripple and a howling noise of the motor, especially when the electric frequency of the motor is in the neighborhood of the DC- link ripple frequency. The origin of DC-link voltage fluctuation and beat phenomena effect are analyzed in detail. For reducing the beat effect of DC-link voltage fluctuation without using an additional resonant filter at DC-link in the traction drive system, a beat-less control scheme based on the frequency modulation and vector control is discussed in detail. Simulation and hardware-in-the-loop (HIL) experimental results confirm the effectiveness and validity of the adopted scheme.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125952176","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}

But energy dissipation of MAO treatment is so large that it has become the most important obstacle of utilizing MAO in many applications. The foremost cause is that the current efficiency of the pulse power supply, which is a key equipment of MAO treatment, is low, and the processing time is long. Because the micro-arc discharge is very complex, the load of power supply has very complex characteristic. Therefore the energy of each pulse couldn't be effectively adjusted by using square voltage or current pulse power supply, which is the most practical approach. This paper proposes a flyback switching current pulse unit which is capable of outputting the spike current pulse. The coupled inductor is used to store and transfer energy, the single pulse energy could be regulated by setting the peak current of primary windings of the inductor. This unit can be used to constitute power supplies with different forms by parallel connection, interleaving parallel connection, anti-parallel connection. Experimental results show that the power consumption of the flyback switching current pulse power supply decreases remarkably comparing with the square current pulse power supply and the processing time of former is shorter than latter. Experimental result of parallel connection units are given to verify the effectiveness.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124600332","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}

But a single IGBT still cannot meet the needs of the high-voltage converters at present. IGBT series and parallel connection can greatly extend the application of IGBT because it can effectively improve the system voltage and current capacity. Generally, the volume of high voltage IGBTs series connection converter is large because of the insulation and thermal performance requirements. It means that the bus bar structure is complex, and the stray parameters of the commutating loops, especially the stray inductance, will significantly influence the switching processes. It becomes one of the key points for the safe operation of the converter. In this paper, the design principles for complex physical bus bar are presented. Based on the finite element analyses, the bus bar structure of a high voltage IGBTs series connection experimental platform is designed and improved. The performance of the improved bus bar structure is verified by simulations and experiments.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128491254","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 mathematical model of STATCOM is firstly deduced in order to design an effective controller. Then, a self-tuning PI controller is designed as a PCC voltage regulator. A PSO algorithm considering the best particle gains, the best global gains, and previous change of gains is applied to achieve the desired PI controller gains when the load is varying.

First, the active power filter is modeled in the stationary abc frame and then the model is transformed to the rotating dq frame with the aim of reducing the control complexity. Then we form an energy-like Lyapunov function and determine the control law that makes the time derivative of the function always negative for all values of the states. At last we give the results of the simulation using the proposed control law.
