The basic principle of pulsating voltage injection is analyzed in detail, and the rotor position and speed estimation system is designed to make improvements. On this basis, a novel sensorless control method based on pulsating current signal injection is proposed in this paper. The two methods are compared by theoretical analysis and simulation. The simulation results indicate that the rotor position and speed can be obtained exactly at low and zero speed by both of the methods, and the method of pulsating current injection is more simple and stable.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773570","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}

In this paper, an indirect self-tuner is proposed for position control of the LSRM by combining the recursive least squares (RLS) estimator with the minimum-degree pole placement method (MDPP) for controller design. Control system construction and operation based on one single Digital Signal Processor (DSP) are also established. Experimental results demonstrate the control scheme with on-line least-square parameter identification has a better performance than PID controller on modifying steady-error variances between each operation side in square-wave tracking. Experimental results prove that the control algorithm considering disturbances has smaller steady-state error compared with PID control algorithm.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127541316","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 developed approach can reduce the circulating energy through the bridge switches using an appropriate choice of the resonant frequency between the transformer leakage inductance and the clamp capacitance in relation to the switching frequency. Thus, current and the voltage stresses can be reduced and the converter efficiency improved. It has also been demonstrated that the use of a voltage-doubling output rectifier enhances the performance further. The optimized active-clamp circuit has been implemented on a 1.2 kW isolated current-fed full-bridge DC-DC converter and test results have confirmed the claimed improvements.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129306180","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}

There are disadvantages of the traditional algorithm, such as the pulse width limit and phase delaying. The improved algorithm, which combines the prediction algorithm and the deadbeat control, can calculate the switching duty cycle of photovoltaic grid-connected inverter in advance and output timely. In this paper, this new method is introduced in detail, and the advantages compared to the traditional algorithm are presented. Simulation experiments are done based on both algorithms. The results verify that the phase of output current tracks the grid voltage better. The power factor is so closed to 1 and the current quality is largely improved.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128468616","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}

Many power engineering students however find it difficult to understand the conducting states of the active switches (transistors, IGBTs) and the passive switches (the anti-parallel diodes connected across the active switches). It seems a mystery to them that power can flow from a lower voltage ac system to a higher voltage dc system to charge the energy storage system. This paper proposes a simple chart that intuitively explains how to determine the states (either conducting or non-conducting) of the active and passive switches of an inverter. The flowchart helps students to understand the cyclic changes in the topology of the circuit in a switching cycle. The flowchart by nature is general and can be used for any type of control methods such as sinusoidal PWM and hysteresis control. The application of the use of this chart is also discussed for a battery energy storage system.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126177138","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 Dual-mode digital controller addresses transient and steady-state modes. To accommodate fast dynamic response, the SMC law is adopted in transient mode. In steady-state mode, the PID control law which is clocked at a frequency lower than the converter switching frequency for consideration of energy consumption is applied to minimize power consumption.
